Latest News
In 2024 and as of 2 October 2024, 18 countries in Europe have reported 1’202 locally acquired human cases of West Nile Virus (WNV) infection with known place of infection. The earliest and latest date of onset were respectively on 1 March 2024 and 26 September 2024.
Locally acquired cases were reported by Italy (422), Greece (202), Spain (114), Albania (102), Hungary (101), Romania (71), Serbia (53), Austria (34), Türkiye (30), France (27), Croatia (20), Germany (8), Slovenia (5), Kosovo (4), Slovakia (4), Bulgaria (2), North Macedonia (2) and Czechia (1).
In Europe, 88 deaths were reported by Greece (31), Italy (16), Albania (13), Romania (10), Spain (10), Bulgaria (2), Serbia (2), Türkiye (2), France (1) and North Macedonia (1).
Case numbers reported this year are above the mean monthly case count for the past 10 years. During the same period in 2023, 681 cases had been reported. However, numbers are lower than in 2018, when 1 728 cases had been reported by this time of year.
Distribution of locally acquired human West Nile virus infections in 2024 till 2 October 2024:
Of note, further regions of infection were reported in 2023.
The following precautions are recommended:
- Protect yourself against mosquito bites during the day and at night (see factsheet mosquito and tick bite protection).
- Do not touch sick or dead birds, as they may also be infected.
- If you have visited a West Nile fever transmission area, do not donate blood for at least 28 days after returning.
In 2024, as of 01 September 2024, 15 countries have reported 3’891 confirmed cases, including 32 deaths. The three countries with the majority of the cases in 2024 are The Democratic Republic of the Congo, (n = 3’361), Burundi, (n = 328), and Nigeria (n = 48).
Note: a significant number of suspected cases, that are clinically compatible with mpox are not tested due to limited diagnostic capacity and never get confirmed. WHO efforts on integrating these data is currently ongoing and will be included in future updates. Not all countries have robust surveillance systems for mpox, so case counts are likely to be underestimates.
According to WHO, in 2024 as of 1 Sept 2024, mpox due to monkeypox virus clade I were reported in (for updates, details, epidemic curves, see WHO LINK):
Clade Ia and b:
- D.R. Congo: According to WHO: 3’361 cases. Increasing trend in number of cases.

This is a 137% increase in the number of new cases reported compared to the last update. Cumulatively, 4’799 confirmed, 17’801 suspected and 610 deaths (CFR: 3.4%) of mpox have been reported from all 26 provinces in DRC. Children <15 years accounted for 66% of cases and 82% of deaths. Of the confirmed cases, 73% were males. Clade Ia and Ib was isolated from the confirmed cases.
Clade Ib

WHO conducted the latest global mpox risk assessment in August 2024. Based on the available information, the risk was assessed as:
- In eastern Democratic Republic of the Congo and neighbouring countries, the overall risk is assessed as high.
- In areas of the Democratic Republic of the Congo where mpox is endemic, mpox risk is assessed as high.
- In Nigeria and other countries of West, Central and East Africa where mpox is endemic, mpox risk is assessed as moderate.
WHO risk assesment, see LINK.
Follow local media and local health authority advice. The following prevention measures should be followed during a stay in countries where mpox is endemic/epidemic (see also Factsheet mpox).
General precautions
- Worldwide:
- Avoid close, skin-to-skin contact with people who have or may have mpox or people who have a rash (e.g., pimples, blisters, scabs).
- Wash your hands often with soap + water or an alcohol-based hand sanitizer containing at least 60% alcohol.
- Avoid touching potentially contaminated personal items such as bedding/clothing, towels or sharing eating utensils/cups, food or drink with a person who has, or may have mpox.
- Avoid sex with sick persons; use of condoms for up to 12 weeks if you sexual partner have had mpox.
- Follow advice of local authorities.
- When travelling to endemic / epidemic areas in Africa, in addition to above mentioned general precautions:
- Avoid contact with and animals in areas where mpox regularly occurs.
- Avoid eating or preparing meat from wild animals (bushmeat) or using products (creams, lotions, powders) derived from wild animals.
- Avoid contact with and animals in areas where mpox regularly occurs.
Vaccination
A vaccination against mpox is available (Jynneos®, manufactured by Bavarian Nordic). The Swiss Expert for Travel Medicine recommends vaccination against mpox in following situations, status 30 August 2024 (the recommendation will be updated regularly depending on the development of the outbreak):
1. People staying or travelling to Eastern D.R. Congo and Burundi in case of:
- Clinical, research or laboratory work
- Working with animals
(of note: broader indication is under discussion)
2. People staying outside of Eastern D.R. Congo and Burundi (worldwide) in case of
- Increase risk (e.g. laboratory workers handling mpox virus, men who have sex with men or trans-persons with multiple sexual partners), see Swiss recommendations: see Link.
At the present time, it is assumed that the available vaccine against mpox (e.g. Jynneos®) is also effective against the new clade I. This vaccine is considered safe and highly effective in preventing severe mpox disease.
In case of symptoms
- Seek medical attention immediately
If you are diagnosed with mpox:
- Please stay at home (isolate yourself) until your mpox rash has healed and a new layer of skin has formed. Staying away from other people and not sharing things you have touched with others will help prevent the spread of mpox. People with mpox should regularly clean and disinfect the spaces they use to limit household contamination.
- Wash your hands often with soap /water or an alcohol-based hand sanitizer containing at least 60% alcohol.
- You should not have sex while symptomatic and while you have lesions or symptoms. Use condoms for 12 weeks after infection. This is a precaution to reduce the risk of spreading the virus to a partner.
- For more information on what do if you are sick, see CDC LINK.
For clinicians:
- Consider mpox as a possible diagnosis in patients with epidemiologic characteristics and lesions or other clinical signs and symptoms consistent with mpox. This includes persons who have been in DRC or, due to the demonstrated risks of regional spread, any of its neighboring countries in the previous 21 days.
- Further information on evaluation and diagnosis: see CDC LINK.
- Following the report of an imported Monkeypox virus (MPXV) clade Ib case in Sweden on 15 August 2024 in a returning traveler from Burundi, Thailand reported a confirmed imported case due to MPXV clade Ib on 22 August 2024. The case is a European man, with travel history to the Democratic Republic of Congo.
- On August 22, 2024, Gabon reported a suspected case of mpox clade Ib in a person with a travel history to Uganda (LINK).
Epidemiological situation: Mpox outbreaks are caused by different clades, clades 1 and 2, see EpiNews as of 16 August 2024. Historically, clade 1 has been associated with a higher percentage of people with mpox developing severe illness or dying, compared to clade 2 (responsible for the global spread in 2022). D.R. Congo (DRC) has been the most affected country, with a large increase of mpox cases due to MPXV clade I being reported since November 2023. In April 2024, sequencing of mpox cases from Kamituga in South Kivu province in eastern DRC, within the context of an observational study, identified a subtype of clade I, clade Ib. Both MPXV clade Ia and clade Ib have been circulating in DRC, while clade Ia has been detected in Congo and Central African Republic.
Geographical spread of the new MPXV clade Ib variant occurs via transport routes through sexual contact (e.g. sex workers), and then local transmission is observed in households and other settings (which are becoming increasingly important).
In recent weeks, confirmed mpox cases due to MPXV clade Ib have been reported by countries neighbouring DRC, such as:
- Burundi (highest number of cases outside DRC): As of 17 August 2024, there had been 545 alerts of mpox cases since the outbreak declaration, of which 474 suspected cases (86.9%) had been investigated and validated. Of 358 suspected cases tested, 142 (39.7%) tested positive for MPXV. Genomic sequencing analysis has confirmed clade Ib MPXV. About 37.5 cases % are among children <10 years old.
- Kenya. 1 case confirmed, for details see LINK. As of 13 August, a total of 14 suspected cases had been identified, one case had tested positive for MPXV Clade Ib, 12 suspected cases had tested negative, and the test result for one case was pending.
- Rwanda: 2 confirmed cases in July and 2 confirmed cases in August.
- Uganda: 2 confirmed cases
On 14 August 2024, WHO declared the current clade I monkeypox virus outbreak a public health emergency of international concern (PHEIC).
The type of exposure reported by cases in DRC includes sexual contact, non-sexual direct contact, household contact and healthcare facility contacts. The cases reported in Rwanda had travel history to DRC and Burundi, investigation showed that the cases reported by Uganda took place outside the country, while the case reported in Kenya was detected at a point of entry. For clade Ib (reported in Eastern DRC, Burundi, Rwanda, Uganda and Kenya), close physical contact (sexual contact) has been documented as the predominant mode of transmission, while for clade Ia (in endemic areas of DRC, Congo and CAR) multiple modes of transmission have been documented including zoonotic transmission.
For details of the cases, epidemiology, public health response and WHO advice, see WHO LINK.
Follow local media and local health authority advice. The following prevention measures should be followed during a stay in countries where mpox is endemic/epidemic:
General precautions:
- Refrain from sexual or other close contact with people who are sick with signs and symptoms of mpox, including those with skin lesions or genital lesions.
- Avoid contact with wild animals (alive or dead) in areas where mpox regularly occurs.
- Avoid contact with contaminated materials used by people who are sick (such as clothing, bedding, or materials used in healthcare settings) or that came into contact with wild animals.
- Avoid eating or preparing meat from wild animals (bushmeat) or using products (creams, lotions, powders) derived from wild animals.
- Avoid sex with sick persons and use of condoms for up to 12 weeks after the convalescence of the sexual partner.
A vaccination against mpox is available (Jynneos®, manufacture Bavarian Nordic). There is an increased demand worldwide with risk of vaccine shortage. The Swiss Expert for Travel Medicine recommends vaccination against mpox in following situations, status 30 August 2024 (the recommendation will be updated regularly depending on the development of the outbreak):

WHO Director-General Dr Tedros has determined that the upsurge of mpox (formerly monkeypox) in the Democratic Republic of the Congo (DRC) and a growing number of countries in Africa constitutes a public health emergency of international concern (PHEIC) under the International Health Regulations (2005) (IHR). The PHEIC will help to take further coordinated international action to support countries in combating disease outbreaks.
This PHEIC determination is the second in two years relating to mpox. Mpox was first detected in humans in 1970, in the DRC. The viral disease is caused by the Monkeypox virus (MPXV), which is present in the wildlife (in certain small mammals) and the disease is considered endemic in countries in central and west Africa. In July 2022, the multi-country outbreak of mpox was declared a PHEIC after an outbreak occurred in Europe and spread rapidly via sexual contact across a range of countries where the virus had not been seen before. That PHEIC was declared over in May 2023 after there had been a sustained decline in global cases.
Since November 2023, the Democratic Republic of the Congo (DRC) has seen a significant increase in mpox cases and the emergence of a new mpox clade I. The country has reported over 16’000 new cases and more than 500 deaths in 2024. Mpox outbreaks are caused by different clades, clades 1 and 2. Historically, clade 1 has been associated with a higher percentage of people with mpox developing severe illness or dying, compared to clade 2. The clades are now subdivided into clade 1a, 1b and clade 2a, 2b.
- Clade 1a is the clade endemic in DRC and other central and East African countries (e.g. the Central African Republic and the Republic of Congo) for decades, it affects mostly children and is spreading through multiple mode of transmission (including animal-to human transmission, close nonsexual contact, sexual contact).
- Clade 1b, identified since September 2023, is currently causing the outbreak in eastern DRC and neighboring countries (Burundi, Rwanda, Kenya, and Uganda; and more recently in a returning traveler from Burundi to Sweden), it affects mostly adults of both sex and is spreading predominantly through intimal contact (sexual networks). Nonsexual transmission is also happening to a lesser extent. At present, there is no evidence that it is more transmissible or more severe than the clade 1a.
- Clade 2a is endemic in various countries of West Africa for decades with low incidence and is spreading through multiple modes of transmission like clade 1a.
- Clade 2b is the clade at the origin of the 2022/2023 global outbreak (116 countries), it affects mostly men (>96%) and is spreading primarily through sexual contact (particularly men having sex with men). It is still ongoing and could affect people with risk factors in all countries around the world, including African countries.

The European Center for Disease Control (ECDC) has issued a risk assessment on 16 August 2024 with specific advice, for details see LINK.
Protect yourself against ticks during outdoor activities (see Factsheet Mosquito Protection). Vaccination is recommended when staying in endemic areas. Complete basic immunisation requires three vaccination doses. Protection for a limited period of time already exists after two vaccination doses. These first two vaccinations are usually given one month apart. The third vaccination is given 5-12 months after the second dose, depending on the vaccine. A booster vaccination is indicated after 10 years.
After recreational activities: Always check your body for ticks or tick bites. If redness occurs after a tick bite: Consult a doctor to rule out Lyme disease, which would require antibiotic treatment.
In the beginning of May 2022, one case of monkeypox was detected in England, which had occurred after travel to Nigeria. In the course of this, 6 further cases of monkeypox were diagnosed in England in people with no previous travel and no contact with known travel-associated cases. These are two cases in one family and four cases in men who have sex with men (MSM). The latter apparently got infected in London. Apart from the family and two of the MSM cases, there are no known links between the cases. Further 2 cases have been reported in the meantime. Investigations into the sources of infection and other suspected cases are in progress.
Additional cases are reported by GeoSentinel and various media reports from the following countries:
- France: 1 suspected case (Île-de-France region).
- Italy: 3 cases, one confirmed, 1 case with travel history Canary Islands (link)
- Canary Islands: 1 suspected case
- Portugal: 14 confirmed cases, another 6 suspected cases (link), Lisbon Region and Tagus Valley Region
- Spain: 7 confirmed, 23 suspected cases, (link)
- Sweden: 1 confirmed case, 1 suspected case
- Canada: 17 suspected cases (link)
- USA: 1 confirmed case with travel history to Canada (link)
Description: Monkeypox is a zoonosis caused by an orthopoxvirus, a DNA virus genetically related to the variola and vaccinia viruses. Monkeypox is endemic in West and Central Africa. Increased cases have been recorded in Nigeria since September 2017, and imports by returning travellers to England and the USA have also been recorded more frequently in recent years. There are two types of monkeypox virus: the West African type and the Central African type (Congo Basin).
Transmission: Monkeypox is transmitted from infected animals by a bite or by direct contact with blood, body fluids or lesions of the infected animal. It can be transmitted via abrasions in the mouth to people who eat infected animals. It can also be transmitted from person to person via the respiratory tract, through direct contact with body fluids of an infected person or with virus-contaminated objects. The incubation period is 5-21 days, usually about 7 to 17 days.
Symptoms: Symptoms of monkeypox include fever, headache, muscle aches, swollen lymph nodes and chills. 1- 3 days after the onset of symptoms, a rash develops that may look like chickenpox or syphilis and spreads from the face to other parts of the body, including the genitals. The disease is usually mild. In immunocompromised individuals, the disease can be severe. The mortality rate is about 1% for the West African type and up to 10% for the Central African type.
For further details, see WHO factsheet, ECDC and CDC.
Further cases must be expected. Persons showing symptoms as described above should contact a doctor, ideally in advance by telephone. Persons who have several sexual partners or practice casual sex should be particularly vigilant!
Prevention: Good personal hygiene, avoid contact with infected persons and animals at all costs. During stays in West and Central Africa: No consumption of bushmeat. The individual risk of contact with a patient with monkeypox depends on the type and duration of contact. In the case of very close contact with a case (e.g. family members, aeroplane neighbours, medical personnel), the risk of infection has so far been classified as moderate; in the case of sexual / intimate contact, it is probably high.

Protect yourself against ticks during outdoor activities (see factsheet mosquito and tick bite protection). Vaccination against TBE is recommended for (planned) stays in endemic areas (CH: throughout Switzerland except cantons of Geneva and Ticino).
After recreational activities: Always examine your body for ticks or tick bites. If redness appears at least 3 days (7-10 days on average) after tick bite: consult a physician to rule out erythema migrans (Lyme disease), which would require antibiotic treatment.
Over 120 cases of salmonella have been reported since 2019 in Germany (68 cases), Sweden (37 cases), Norway (5 cases), Denmark (9 cases), and the Netherlands (2 cases). Cases have also been reported in the United States and Canada. The salmonella outbreak is linked to sesame products (tahini and halva) imported from Syria. Fourteen batches have tested positive for one or more of the Salmonella-outbreak strains. Tahini is a paste made from raw sesame seeds. Halva is a confectionery product that contains a high percentage of sesame seeds.
The recurrent occurrence of cases and the repeated discovery of positive samples since 2019 indicate that contaminated sesame-based products have been circulating in the EU market for more than two years.
Consequences for travelers
Considering the limited information on the production and distribution of the sesame products from Syria, there is still a risk of new salmonella infections in the EU/European Economic Area. Caution should be shown when consuming these products (tahini, halva).

- Covid-19 is a disease that affects the whole body, but mainly shows with respiratory symptoms such as cough and difficulty in breathing. It is caused by the SARS-CoV-2 virus.
- The infection is mainly spread through respiratory droplets and possibly aerosols when infected persons cough, sneeze, speak or sing without wearing a mask.
- The infection can be prevented very effectively by vaccination and an increasing number of vaccines are now approved and available for protection.
- Vaccination is recommended according to the Swiss recommendations of the Federal Office of Public Health (FOPH), see LINK.
- Furthermore, prevention relies heavily on people wearing face masks, on hand hygiene and on physical distancing (min. 1.5 m) if masks are not worn and people are not vaccinated.
- Influenza is common all over the world including sub-tropical and tropical countries.
- Vaccination offers the best protection.
- Vaccination against flu is recommended for all travellers who belong to an “at risk” group such as pregnant travellers, travellers with comorbidities, elderly people (>65 years), or who plan a a high-risk trip (e.g. cruise-ship, pilgrimage).
- The influenza vaccine does not offer protection against avian flu.

- Sexually transmitted infections (STIs) are a group of viral, bacterial and parasitic infections; while many are treatable, some can lead to complications, serious illness or chronic infection.
- STIs are increasing worldwide.
- Read the following fact sheet for more information.
- Geschlechtskrankheiten sind ein weltweit verbreitetes Gesundheitsproblem und können durch Prävention, regelmässiges Testen und Behandlung in den Griff bekommen werden.
- Das Wissen um Risiken sowie Safer-Sex-Praktiken inklusive Kondomgebrauch sind wichtig. Falls Sie mehr dazu erfahren wollen, wie Sie sich während der Reise optimal schützen können, besprechen Sie dies mit einer Fachperson.
- Hatten Sie eine Risikosituation, ist es wichtig mit einer Fachperson so rasch wie möglich Rücksprache zu halten, um zu erörtern, ob eine HIV-Post-Expositions-Prophylaxe (PEP) durchgeführt werden soll, um eine Ansteckung mit HIV zu verhindern.
- Im Nachgang einer Risikosituation ist es wichtig sich auf Geschlechtskrankheiten testen zu lassen. Auch dann, wenn Sie keine Symptome haben.
- Brennen oder Juckreiz im Genitalbereich
- Schmerzhaftes oder häufiges Wasserlösen oder auch Schmerzen im Unterleib
- Ungewöhnlicher Ausfluss aus dem Penis oder der Vagina
- Wunden, Rötungen, Bläschen im Mund/Lippen oder Genitalbereich sowie Warzen im Intimbereich
- Manchmal auch Fieber (eher selten)
Wichtig: Eine STI kann auch ohne oder mit nur leichten Symptomen auftreten. Auch wenn Sie sich dessen nicht bewusst sind, können Sie andere anstecken. Deshalb ist es wichtig sich testen zu lassen.
- Beachten Sie die Safer Sex Regeln von Love Live. Dazu gehört auch bei jedem Anal- oder Vaginalverkehr Kondome zu verwenden.
- Denken Sie daran, dass es bei Oralverkehr auch zu Übertragungen von STIs kommen kann.
- Lassen Sie sich impfen! Es gibt Impfstoffe zum Schutz vor HPV, Hepatitis A und Hepatitis B.
- Hatten Sie eine Risikosituation, ist es wichtig mit einer Fachperson so rasch wie möglich Rücksprache zu halten, um zu erörtern, ob eine HIV-Post-Expositions-Prophylaxe (PEP) durchgeführt werden soll, um eine HIV-Infektion zu verhindern. Am wirksamsten ist eine HIV-PEP innerhalb weniger Stunden danach.
- Es gibt auch weitere Präventionsmassnahmen für spezielle Situationen (Präexpositionsprophylaxe HIV-PrEP). Sprechen Sie mit einer damit erfahrenen Fachperson vor Abreise darüber.
- Denken Sie daran, dass Alkohol oder Drogen zu erhöhtem Risikoverhalten führen.
- Denken Sie daran, dass Sie eine weitere Person/bekannter Partner*in bei ungeschütztem Sex anstecken können, sofern bei Ihnen eine unbehandelte STI vorliegt.
- Menschen mit einer neu diagnostizierten STI sind angehalten ihre früheren Sexualpartner*innen zu informieren, damit auch sie behandelt werden können.

Alle diese Krankheiten können geheilt werden. Wichtig ist dabei, frühzeitig zu testen und umgehend zu therapieren, um Komplikationen und v.a. weitere Übertragungen zu vermeiden.
- Syphilis
Auch bekannt als Lues. Sie wird durch das Bakterium Treponema pallidum verursacht. Das erste Anzeichen ist eine schmerzlose Wunde an den Genitalien, im Mund, auf der Haut oder im Rektum, die hochgradig ansteckend ist und nach 3 bis 6 Wochen spontan abklingt. Da diese schmerzlos ist, nehmen nicht alle Patienten*innen diese Läsion wahr. Oft heilt diese Infektion jedoch nicht von selbst aus. In der zweiten Phase können Hautausschlag, Halsschmerzen und Muskelschmerzen auftreten. Unbehandelt kann die Krankheit im Verborgenen (latent) bleiben, ohne dass Symptome auftreten. Etwa ein Drittel der Infizierten mit unbehandelter Syphilis entwickelt im Verlauf Komplikationen. Diese Spätform wird als sogenannt tertiäre Syphilis bezeichnet . In diesem Stadium kann die Krankheit alle Organe befallen: am häufigsten das Gehirn, die Nerven und die Augen. Die Infektion kann während der Schwangerschaft auf den Fötus und bei der Geburt auf das Kind übertragen werden. - Chlamydia trachomatis
Chlamydien können ungewöhnlichen Ausfluss aus dem Penis oder der Vagina, Unbehagen beim Wasserlösen und Unterleibsschmerzen verursachen. Oft treten keine Symptome auf. Unbehandelt können sie zu Unfruchtbarkeit führen und die Krankheit kann auf Sexualpartner*innen übertragen werden. Die Bakterien können auch während der Schwangerschaft auf den Fötus, oder während der Geburt auf das Kind übertragen werden und Augeninfektionen oder Lungenentzündungen verursachen. - Gonorrhoe
Auch bekannt als Tripper. Zu den häufigsten Symptomen gehören Ausfluss aus der Vagina oder dem Penis und schmerzhaftes Wasserlassen. Symptome müssen aber nicht immer auftreten. Sowohl bei Männern als auch bei Frauen kann Gonorrhoe auch den Mund, den Rachen, die Augen und den Anus infizieren und sich auf das Blut und die Gelenke ausbreiten, wo sie in eine schwere Krankheit übergehen kann. Bleibt sie unbehandelt, kann sie eine Beckenentzündung verursachen, die zu chronischen Beckenschmerzen und Unfruchtbarkeit führen kann. Die Krankheit kann während der Schwangerschaft auf den Fötus übertragen werden. - Weitere bakterielle STIs: Mykoplasmen und Ureaplasmen. Diese können ebenfalls behandelt werden.
- Trichomoniasis
Sie wird durch einen Parasiten verursacht, der mit einer einzigen Dosis eines Antibiotikums behandelt werden kann. Trichomoniasis kann bei Frauen einen übel riechenden Scheidenausfluss, Juckreiz im Genitalbereich und schmerzhaftes Wasserlassen verursachen. Bei Männern treten in der Regel weniger oder keine Symptome auf. Zu den Komplikationen gehört das Risiko einer vorzeitigen Entbindung bei schwangeren Frauen. Um eine Reinfektion zu verhindern, sollten beide Sexualpartner behandelt werden.
Durch Viren hervorgerufen
- HIV/AIDS - siehe Informationsblatt HIV-AIDS
- Herpes simplex Virus
Im Lippen-Mundbereich, auch bekannt als Fieberbläschen, ist nicht heilbar. Herpes kann aber mit Medikamenten bei akuten Beschwerden kontrolliert werden. Die Symptome sind in der Regel schmerzhafte, wässrige Hautbläschen und finden sich an oder um die Genitalien, den Anus oder den Mund. Nach der Erstinfektion ruht das Virus im Körper und die Symptome können über Jahre hinweg wieder auftreten. Schwangere Frauen können die Infektion an ihre Neugeborenen weitergeben, was zu einer bedrohlichen Infektion führen kann. - Virale Hepatitis (siehe auch Hepatitis Schweiz)
- Hepatitis A (HAV)
Hepatitis A ist eine durch Impfung vermeidbare Leberinfektion, die durch das Hepatitis-A-Virus verursacht wird. Das Hepatitis-A-Virus findet sich im Stuhl und im Blut infizierter Personen. Hepatitis A kann durch verunreinigtes Wasser und Lebensmittel sowie bei anal-oralen sexuellen Aktivitäten übertragen werden. Die Patienten*innen leiden an einer akuten und oft schweren Erkrankung, erholen sich aber allermeist spontan. - Hepatitis B (HBV)
Das Hepatitis-B-Virus wird durch sexuelle Kontakte sowie durch den Kontakt mit anderen Körperflüssigkeiten, wie z.B. Blut, übertragen. Zur Übertragung kann es z.B. auch bei medizinischen Eingriffen oder Brennen eines Tatoos unter nicht optimalen hygienischen Bedingungen kommen. Hepatitis B kann eine schwere Leberinfektion verursachen, die sowohl zu einer sofortigen Erkrankung, als auch zu einer lebenslang andauernden Infektion führen kann mit möglicher Folge einer dauerhaften Lebervernarbung (Zirrhose) und Krebs. Schwangere Frauen mit Hepatitis B können das Virus während der Geburt auf ihr Kind übertragen. Zu Beginn der Infektion haben Sie möglicherweise keine Symptome. Das Virus kann auf Sexualpartner*innen übertragen werden. Hepatitis B kann mit antiviralen Medikamenten behandelt werden, ist aber nur selten heilbar. Eine Impfung kann eine Hepatitis-B-Infektion verhindern. - Hepatitis C (HCV)
In den meisten Fällen wird Hepatitis C durch den Kontakt mit infiziertem Blut übertragen. Seltener kann es durch analen Sexualkontakt oder von der Mutter auf das Kind während der Schwangerschaft und Geburt übertragen werden. Die meisten Infizierten sind sich ihrer Infektion nicht bewusst, weil sie keine Symptome entwickeln, aber diese chronische Infektion kann zu Leberzirrhose und Krebs führen. Hepatitis C kann behandelt werden, eine Impfung gibt es nicht.
- Hepatitis A (HAV)
- Humanes Papillomavirus (HPV)
HPV ist die häufigste Geschlechtskrankheit. Es gibt eine Vielzahl verschiedener HPV-Typen, und einige von ihnen können Genital-, Anal- und Mundwarzen sowie Gebärmutterhals-, Penis- oder Rachenkrebs verursachen. Die Symptome können auch noch Jahre nach dem Sex mit einer infizierten Person auftreten. Zwei verfügbare Impfstoffe schützen gegen die wichtigsten HPV-Typen, die Gebärmutterhals-, Penis- oder Analkrebs verursachen. - Zika - siehe Informationsblatt Zika
In den meisten Fällen wird es vor allem durch Stechmücken übertragen. Es kann aber auch sexuell übertragen werden. Eine Ansteckung mit Zika während der Schwangerschaft kann bei dem sich entwickelnden Fötus Geburtsfehler wie Mikrozephalie (kleiner Kopf mit neurologischen Ausfällen) verursachen. Die einzige Möglichkeit, eine sexuelle Übertragung des Virus während der Schwangerschaft zu verhindern, besteht darin, Vorsichtsmassnahmen (Kondome) zu treffen oder Sex (mindestens 2 Monate nach der Rückkehr) mit jemandem zu vermeiden, der kürzlich in ein Risikogebiet gereist ist, auch wenn der Reisende keine Symptome hat.

- Altitude sickness can be life-threatening and may be experienced by any traveler.
- The danger begins at around 2500m and rises with increasing altitude.
- People differ in their susceptibility to altitude sickness; this is not related to their physical fitness.
- Severe altitude sickness with fluid accumulation in the brain or lungs can rapidly result in death.
- If you are planning a stay in high altitudes, we strongly recommend you to consult your doctor for detailed recommendations and instructions.
- Eine Höhenkrankheit kann lebensgefährlich sein und bei jedem Reisenden auftreten.
- Die Gefahr beginnt bei ca. 2500m und nimmt mit zunehmender Höhe zu.
- Wenn Sie einen Höhenaufenthalt planen, lesen sie bitte dieses Merkblatt aufmerksam durch!
- Je nach Reiseart und / oder Vorerkrankungen wird die Beratung durch eine Fachperson dringend angeraten.
- Langsamer Aufstieg. Aufstiegsregeln: oberhalb von 2500m sollte die Schlafhöhe um nicht mehr als 300-500m pro Tag gesteigert werden und pro 1000m Schlafhöhengewinn sollte ein zusätzlicher Ruhetag eingelegt werden.
- Treten Beschwerden auf, die auf eine Bergkrankheit hinweisen (siehe oben), muss der Anstieg pausiert werden und er darf erst wieder bei Beschwerdefreiheit fortgesetzt werden. Bei Zunahme der Beschwerden muss abgestiegen werden bzw. Patient:innen in tiefere Lagen abtransportiert werden. Bei Ignorieren zunehmender Beschwerden können sich die lebensbedrohlichen Formen der Höhenkrankheit, das Höhenhirnödem und/oder das Höhenlungenödem entwickeln.
- Ist das Einhalten der oben genannten Aufstiegsregeln situativ oder geländebedingt nicht möglich, kann die Einnahme von Acetazolamid (DIAMOX®) das Risiko eine akute Höhenkrankheit zu entwickeln, vermindern. Die Verschreibung des Medikaments bedingt eine ärztliche Indikationsstellung sowie eine Aufklärung über allfällige Nebenwirkungen!
- Kopfschmerzen: Paracetamol (z.B. PANADOL®, DAFALGAN®). Keine Schlafmittel verwenden!
- Höhenhirnödem: sofortiger Abstieg. Falls verfügbar: Sauerstoffgabe, medikamentöse Notfalltherapie.
- Höhenlungenödem (Atemnot auch in Ruhe, rasselndes Atemgeräusch, Reizhusten) Sofortiger Abstieg. Falls verfügbar: Sauerstoffgabe, medikamentöse Notfalltherapie.
- Dengue fever is a viral disease that is disease that bite during daytime.
- The best way to prevent these diseases is to protect yourself from mosquito bites, see LINK!
- A vaccination (Qdenga®) against dengue is available.
- However, based on the data available, the Swiss Expert Committee for Travel Medicine (ECTM) currently recommends vaccination with Qdenga® only for travellers who have evidence of previous dengue infection and who will be exposed in a region with significant dengue transmission, for details see LINK.
- In case of fever: do not use any medication containing acetylsalicylic acid (e.g. Aspirin®, Alcacyl®, Aspégic®), as this can worsen bleeding in case of dengue infection.
- Read the following information for optimal travel preparation.

- Marburg virus disease is a rare but severe hemorrhagic fever.
- The disease spreads through contact with infected animals or people.
- Symptoms can be similar to other tropical diseases
- There is no licensed treatment or vaccine for Marburg disease, and
- Please have a look to the factsheet below.
- Marburg virus disease is a rare but severe hemorrhagic fever.
- The disease spreads through contact with infected animals or people.
- Symptoms can be similar to other tropical diseases
- There is no licensed treatment or vaccine for Marburg disease, and
- Prevention measures are important to follow, see below.
The incubation period (time between infection and onset of symptoms) ranges from a 2 to 21 days (usually 5 to 10 days). The onset of MVD is usually abrupt, with initially non-specific, flu-like symptoms such as a high fever, severe headache, chills and malaise. Rapid worsening occurs within 2–5 days for more than half of patients, marked by gastrointestinal symptoms such as anorexia, abdominal discomfort, severe nausea, vomiting, and diarrhoea. As the disease advances, clinical manifestations can become more severe and include liver failure, delirium, shock, bleeding (hemorrhaging), multi-organ dysfunction and death.
In case of symptoms
If think that you have had an exposure at risk and develop fever with nonspecific symptoms such as chills, headache, muscle pain, malaise or abdominal pain:
- you should separate yourself from others (isolate) immediately and
- immediately seek medical advice by contacting the in-country hotline by phone or contact a tropical institute or university hospital infectious disease unit.
- alert the healthcare providers of your recent travel to an area with a Marburg outbreak.
The risk for travellers is very low if the below precautions are followed, but it is high for family members and caregivers who have contact with sick people.
General precautions during travel to affected areas:
- Wash your hands regularly and carefully using soap and water (or alcohol gel if soap is unavailable).
- Avoid contact with sick people who have symptoms, such as fever, muscle pain, and rash.
- Avoid contact with blood and other body fluids
- Avoid visiting healthcare facilities in the MVD-affected areas for nonurgent medical care or non-medical reasons.
- Avoid contact with dead bodies or items that have been in contact with dead bodies, participating in funeral or burial rituals, or attending a funeral or burial.
- Avoid handling, cooking, or eating bush/wild meat (meat of wild/feral mammals killed for food).
- Wash and peel fruit and vegetables before consumption.
- Avoid visiting mines or bat caves and contact with all wild animals; alive or dead, particularly bats.
- If you decide to visit mines or caves inhabited by fruit bat colonies, wear gloves and other appropriate protective clothing, including masks and eye protection.
- Practice safer sex.

- Mpox is a viral disease that typically causes a rash, swollen lymph nodes and fever.
- An emerging variant is spreading rapidly in eastern D.R. Congo and neighbouring countries, leading the WHO to declare a new Public Health Emergency International (PHEIC) in August 2024.
- Close physical contact (sexual or non-sexual) is the main route of transmission.
- The disease is usually mild. Children, pregnant women and people with weakened immune systems are most at risk of complications.
- Take general precautions (see factsheet) to prevent the disease.
- There is a vaccination against Mpox, but it is currently only available for people at high risk.
- Mpox is a viral disease that typically causes a rash, swollen lymph nodes and fever.
- An emerging variant is spreading rapidly in eastern D.R. Congo and neighboring countries prompting a new WHO declaration of a public health emergency of international concern (PHEIC), as of August 14th 2024.
- Close physical contact (sexual or non-sexual) is the main mode of transmission.
- The disease generally follows a mild course. Children, pregnant women, and people with weak immune systems are the most at risk of complications.
- Vaccination against mpox is available, but limited to groups at high risk of exposure.
Mpox has been commonly found in West and Central Africa for many years where the suspected reservoir - small mammals - is endemic. There are two types of Monkeypox virus called ‘clades’ that cause the disease mpox - clade I in Central Africa and clade II in West Africa. Since the end of smallpox vaccination campaigns in the early 1980’s, cases of mpox have increased, slowly at first and significantly in the last 5-10 years, especially in the Democratic Republic of Congo (DRC).
In 2022, a new emerging subclade of clade II was responsible for a global epidemic that spread mainly through sexual contact among men who have sex with men. It resulted in the first public health emergency of international concern (PHEIC) declared by the WHO until 2023. Although the clade II epidemic is now under control, this virus variant continues to circulate worldwide.
In 2024, the continued spread of mpox clade I in endemic regions of Central Africa, particularly in the DRC, and the emergence of a new subclade Ib in Eastern DRC and neighboring countries have raised global concern and prompted the WHO to declare a PHEIC for the second time in two years. The current geographical spread of the mpox clade Ib variant occurs via commercial routes through sexual contact (e.g. sex workers), followed by local transmission in households and other settings (which is becoming increasingly important).
Animal to human transmission
Mpox can spread from animal to human when they come into direct contact with an infected animal (rodents or primates).
Human to human transmission
Mpox can be spread from person to person through close physical contact (sexual and non-sexual contact) with someone who has symptoms of mpox. Skin and mucous membrane lesions, body fluids, and scabs are particularly infectious. A person can also become infected by touching or handling clothing, bedding, towels, or objects such as eating utensils/dishes that have been contaminated by contact with a person with symptoms. Household members, family caretakers, and sexual partners of a confirmed case of mpox are at higher risk for infection as are health care workers who treat a case without adequate personal protection.
The incubation period (time between infection and onset of symptoms) ranges from a few days up to 3 weeks. Mpox causes a rash / skin eruption that can be painful associated with swollen lymph nodes and fever. Fever may start already before the rash phase. Other symptoms include muscle aches, back pain, and fatigue. The rash may be localized or generalized, with few or hundreds of skin lesions. It mainly affects the face, the trunk and the palms of hand and soles of the feet. It can also be present in genital areas and on mucous membranes such as in the mouth and throat. Symptoms usually last 2 to 4 weeks and the person remains contagious until all lesions have healed (once the cabs have fallen off).
Complications include secondary bacterial infections, infections of the lung and brain and involvement of other organs, still birth and others. Children, pregnant women, and people with weak immune systems are at higher risk to develop a severe form of mpox.
The majority of person with mpox recovers spontaneously and do not need specific antiviral treatment. Care management consists of relieving pain and other symptoms and preventing complications (e.g., superinfection). Several antiviral treatments are studied in various countries and may be used in trials or in clinical situations according to the recommendations of national medical societies.
In case of symptoms:
- Seek medical attention immediately
- If you are diagnosed with mpox
- Please stay at home (isolate yourself) until your mpox rash has healed and a new layer of skin has formed. Staying away from other people and not sharing things you have touched with others will help prevent the spread of mpox. People with mpox should regularly clean and disinfect the spaces they use to limit household contamination.
- Wash your hands often with soap and water or an alcohol-based hand sanitiser containing at least 60% alcohol.
- You should not have sex while symptomatic and while you have lesions or symptoms. Use condoms for 12 weeks after infection. This is a precaution to reduce the risk of spreading the virus to a partner.
- For more information on what do if you are sick, see CDC LINK.
General precautions:
- Worldwide:
- avoid close, skin-to-skin contact with people who have or may have mpox or people who have a rash (e.g., pimples, blisters, scabs).
- Wash your hands often with soap and water or an alcohol-based hand sanitiser containing at least 60% alcohol.
- Avoid touching potentially contaminated personal items such as cups, bedding/clothing, towels or sharing eating utensils/cups, food or drink with a person who has, or may have mpox.
- Avoid sex with sick persons; use of condoms for up to 12 weeks if you sexual partner have had mpox.
- Follow advice of local authorities.
- When travelling to endemic / epidemic areas in Africa, in addition to above mentioned general precautions:
- Avoid contact with and animals in areas where mpox regularly occurs.
- Avoid eating or preparing meat from wild animals (bushmeat) or using products (creams, lotions, powders) derived from wild animals.
Vaccination:
There are several vaccines against mpox (e.g. Jynneos®, manufacture Bavarian Nordic). The Bavarian Nordic vaccine was originally developed to fight against smallpox, but offers a cross-protection against mpox. In Switzerland, the Jynneos® vaccine has been licensed by Swissmedic since 2024. Groups at risk (e.g., men who have sex with men or transgender people with multiple sex partners) are eligible for vaccination since 2022 and this recommendation remains unchanged (see FOPH recommendations). In light of the epidemiological situation in Africa in 2024, the Swiss Expert Committee for Travel Medicine recommends vaccination against mpox for professionals who are / will be in contact with suspect mpox patients or animals in endemic/epidemic regions or who work in a laboratory with the virus (for updates, see news).
The risk to the general population and travelers (tourists) is considered extremely low if the above-mentioned general precautions are followed and vaccination is not recommended.
- Seek medical attention immediately.
- Mpox is not a sexual transmitted disease in the strict sense, physical contact with a person with symptoms of mpox (rash at any stage) is sufficient to transmit the disease. Condoms do not protect you from getting mpox!
- There are other important travel related health risks such as diarrhoea, road traffic accidents, air pollution and more.
