In October 2023, the following countries reported meningitis outbreaks:
Epidemic:
Warning:
Seasonal meningitis epidemics occur in sub-Saharan Africa mainly during the dry season, usually from December to June. They decline rapidly with the onset of the rains. In general, the meningococcal serogroups A, C, W and X are responsible for these outbreaks. The disease spreads from person to person by droplets. If symptoms (high fever, severe headache and vomiting) occur, a doctor should be consulted immediately and antibiotic therapy started, as the disease can lead to life-threatening conditions within hours. Vaccination against the most important meningitis strains is available as prophylaxis for adults and children over 1 year of age.
Prevention: Good personal hygiene. Avoid close contact with sick people, including those with skin lesions or genital lesions. Avoid contact with sick animals. Avoid contact with contaminated materials used by sick people. Safer sex is recommended to prevent other sexually transmitted diseases. Do not eat bush meat.
Vaccination against Mpox is available and recommended for people at increased risk. Talk to your doctor about whether such a vaccination is recommended for you. Swiss recommendations: see LINK.
In case of symptoms: If you are diagnosed with Mpox, you should not have sex while you have symptoms and lesions. Use condoms for 12 weeks after infection. This is a precautionary measure to reduce the risk of transmitting the virus to a partner. Wash your hands frequently with soap and water or an alcohol-based hand sanitizer containing at least 60% alcohol.
On the World AIDS Day on December 1, here is a look back at the extent of the pandemic:
In 2022:
Since the beginning of the epidemic:

In Denmark, whooping cough (pertussis) cases have increased significantly during the spring and summer, with the authorities now reporting a figure more than ten times higher than normal. In the 37th week alone (up to September 16), 200 cases of whooping cough were detected (normally an average of around 20 cases per week).
Whooping cough is a respiratory infection that is characterized by a course lasting up to three months with severe coughing fits, often accompanied by howling breathing and vomiting immediately after the attacks.
An 8-year-old girl died of rabies in Agra, Uttar Pradesh, on October 25, 2023, after being bitten by a stray dog two weeks earlier. The child did not inform anyone in her family except her mother about the incident, and she was only given some home remedies instead of the necessary rabies vaccine. The family only contacted the Community Health Center when the girl developed symptoms after 15 days.
According to officials, as many as 5000 cases of dog bites are reported every month in both rural and urban Agra.
Ethiopia has faced malaria outbreaks in numerous regions since early 2023. The regions most affected include Gambela, Southwest Ethiopia (SWEPR), Afar, and Ahmara.
In addition to malaria, Ethiopia faces other health crises, including cholera, measles, dengue fever, and COVID-19, as well as a variety of natural disasters such as droughts, recurrent floods, food insecurity, and locust infestations, as well as man-made challenges such as conflict, internal displacement, and the effects of the Sudan conflict. These factors combined have significantly increased the country's need for health and humanitarian assistance.

Although the Tanzania Ministry of Health document is of poor quality and was issued in 2016, travelers with this document have had no problems entering mainland Tanzania. To emphasize the timeliness of this document, the Swiss EKRM recommends that it be stamped by your travel clinic and dated and signed by you.
This tragic case demonstrates the importance of being informed about rabies and acting quickly in the event of a bite or scratch by a mammal in a rabies-endemic country.
Prevention: Avoid contact with animals! Do not feed animals either! Pre-exposure vaccination (2 injections and a booster after 1 year) is recommended especially for travelers with increased individual risk (traveling with two-wheelers, to remote areas, long-term stays, small children, cave explorers, contact with bats, etc.).
Behavior after exposure: After an animal bite/scratch: Immediately wash the wound with running water and soap for 15 minutes, then disinfect and in any case visit a good medical facility as soon as possible for follow-up vaccination!
For more information: see flyer rabies.
In the Indian state of Assam (north-eastern part of the country), 432 cases of Japanese encephalitis (JE) were reported by the end of August, 24 of which were fatal. Cases have increased almost tenfold since the beginning of August 2023.
Ranchi district in Jharkhand state in northern India has also reported an increase in JE cases, although the numbers are still modest, with 12 cases in recent weeks.
The risk for travellers is low. Optimal protection against mosquito bites, especially at dusk and at night.
The indication for vaccination against Japanese encephalitis should be discussed individually and is recommended for:
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.
According to media reports, a case of canine rabies has been reported in the city of São Paulo in Brazil. The infection was confirmed by the Pasteur Institute. This is the first case of canine rabies since 1983.
The case is still under investigation and has already led to surveillance measures in the region and 367 animals have been vaccinated with rabies vaccine.
Information about rabies and what to do in case of exposure is important for all travelers!
Prevention: Avoid contact with animals! Do not feed animals either! Pre-exposure vaccination (2 injections and a booster after 1 year) is recommended especially for travelers with increased individual risk (traveling with two-wheelers, to remote areas, long-term stays, small children, cave explorers, contact with bats, etc.).
Post-exposure behavior: After an animal bite/scratch: Immediately wash the wound with soap and water for 15 minutes, then disinfect and in any case visit a quality medical center for post-exposure vaccination as soon as possible! For more information: see factsheet rabies.
Since the first week of August and as of 11 September 2023, 19 locally acquired dengue fever cases have been detected in the Lombardy (14) and Lazio (5) regions in Italy. The cases are grouped in three clusters:
All cases were laboratory confirmed by PCR and all cases have recovered or are improving.
A DENV-1 serotype virus was identified in the cases in Lombardy and in the metropolitan city of Rome, Lazio region. Epidemiological investigations have not identified any link between the cases in Lombardy and the cases identified in the Lazio region.
A DENV-3 serotype was detected in the cluster of cases in the province of Latina, Lazio region, indicating that this outbreak is independent from the other two in Italy.
Response and control measures are being implemented by Italian public health authorities. These include case finding, vector control activities, information to healthcare providers and the general public, and preventive measures for donors of substances of human origin (e.g. blood and organs).
So far, 146 imported dengue cases have been registered in Italy in 2023, most of them in the Lombardy region (50 imported cases) and Lazio region (28 imported cases).
For more details of the outbreak in Italy, see Rapid Communication of Eurosurveilance.
An outbreak of 4 autochthonous (locally transmitted) cases of dengue fever was detected in Gardanne in the department of Bouches-du-Rhône. Symptoms of the cases occurred between the second half of July and early August 2023.
At least 47 autochthonous cases were recorded in France in 2022. The affected regions were Occitania (9 cases) and Provence-Alpes-Cote d'Azur (36 cases).
Officials observe that the downward trend in terms of chikungunya continues, with a weekly average of about 40 cases per week in the last 3 weeks, dengue cases still remaining at an average of 100 weekly cases. The high dispersion of the cases is also maintained, covering practically the entire national territory.
The head of Health Surveillance, Guillermo Sequera, stated that it is striking that at the end of July we still have cases of dengue and chikungunya (usually there are no cases at this time). He expressed his concern about this scenario, considering that the rainy season is approaching -in October-, to this is added the phenomenon of El Niño, which could portend a complicated epidemiological scenario for the next season.
A man has been hospitalized in Ulan Bator with bubonic plague after eating marmot meat. This was reported by the National Center for the Study of Zoonotic Infections of Mongolia. According to Xinhua News Agency, the hospitalized man and 5 other people who were in close contact with him have been isolated.
While hunting marmots is illegal in Mongolia, many Mongolians regard the rodent as a delicacy and ignore the law. Of all the 21 Mongolian provinces, 17 are still at risk of the bubonic plague, urging the public not to hunt marmots or eat marmot meat.
According to the media, 8.64% of respiratory specimens handled by public laboratories tested positive for flu, higher than 8.57% recorded the week before, but below the baseline threshold level of 9.2%. The latest fatal case involved a 2-year-old boy who tested positive for influenza A and died on 28 July 2023.
Hong Kong has 2 flu seasons, one beginning in April and the second starting in August.
The ministries of health and agricultural development of the province have declared an epidemiological alert after the detection of cases of suspected trichinosis in the interior of Buenos Aires. So far, 29 people have been reported to have been exposed, 15 of whom developed symptoms; from the municipalities of Adolfo Alsina and Sallikelo, and the products included bacon and dried chorizo.
Samples of both products analyzed by the Applicant's laboratory tested positive for Trichinella spiralis. The sausages came from the plant "AGROINDUSTRIA LOS ANDRES SRL", with the trademark "Don Andrés" RPE No. 122-5 PAMS Exp No. 22500-39417/17 found in salami.
According to preliminary information, these products were distributed in the municipalities of Dayro, Hipólito Yrigoyen, Coronel Suárez, Saavedra, Tres Lomas, Trenque Lauquen, Puan, Rivadavia and Adolfo Alsina. Faced with this, medical teams were called in to strengthen the epidemiological surveillance of cases of trichinosis in the said municipalities, and the secretariats of health and food science departments of these areas were urged to continue the investigation.
Trichinellosis is a food-borne helminth infection caused by Trichinella spiralis. Homemade jerky and sausage are often the cause of many cases of trichinellosis. Salting, drying, freezing, smoking or microwaving meat alone does not consistently kill infective worms.
Therefore: Consume only well-cooked meat!
Optimal mosquito protection 24/7 (during the day against dengue, Zika, Chikungunya and other arboviroses, in the evening and at night against malaria). If you have a fever, take acetaminophen products and make sure you drink enough fluids. Do not take medications containing acetylsalicylic acid (e.g., Aspirin®), as they may increase the risk of bleeding. During and after a stay in a malaria endemic area, malaria should also be considered in case of fever and should always be ruled out by a blood test.
Optimal mosquito protection 24/7 (at dusk and at night against malaria, during the day against dengue, chikungunya and other arboviroses). Drug prophylaxis is recommended for parts of Palawan, see detailed information on the Phiilippines country page.
In case of fever >37.5° C, malaria should always be considered and excluded by blood tests.
So far this season (2023), 6 cases of Murray Valley Encephalitis (MVE) have been recorded, two of which were fatal. The Kimberley region has been particularly affected. This has been the worst season for MVE since 2012. Other arboviruses are also transmitted in Western Australia: dengue virus, Ross River virus, Japanese encephalitis virus, Barmah Forest virus, Kunjin virus, etc.
Murray Valley encephalitis virus is transmitted by mosquitoes. The risk of contracting and becoming ill is low, but the illness caused by the virus can be severe and possibly fatal.
Initial symptoms include fever, drowsiness, headache, stiff neck, nausea and dizziness. People who experience these symptoms should seek medical attention as soon as possible.
The Blitar District Health Office in East Java, Indonesia, reported 11 suspected diphtheria cases in the past 2 months, all of which required a stay in the intensive care unit of a hospital.
Diphtheria is caused by bacteria that are common worldwide. The pathogen produces a powerful toxin that can permanently damage organs such as the heart and liver. There are two types of the disease: respiratory (breathing) and cutaneous (skin) diphtheria. The pathogen primarily affects the upper respiratory tract and produces a toxin that can lead to dangerous complications and late effects. Person-to-person transmission occurs through droplet infection (close physical contact, coughing, sneezing). It originates from a sick person or from someone who carries the bacterium without symptoms. Less commonly, infection occurs through contaminated objects or, in the case of cutaneous diphtheria, through direct contact. Effective vaccination protects against the disease.
Protect yourself against ticks during outdoor activities (see Mosquito Protection Factsheet). Vaccination is recommended when staying in endemic areas. Complete basic immunization requires three doses of vaccine. Temporary protection exists after only two doses of vaccination. 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 examine their body for ticks or tick bites. If redness occurs after tick bite: Consult a physician to rule out Lyme disease, which would require antibiotic treatment.
In recent years, the world, and the Americas region in particular, has seen an exponential increase in international travel in search of medical care. While most patients seek this in the country in which they reside, there is a growing proportion of individuals who change countries for medical, dental or surgical treatment. This practice is referred to as medical and health tourism. For example, millions of Americans travel to other countries each year for medical care, especially to Mexico, Canada, and other countries in Central America, South America, and the Caribbean.
While there are few published studies on the number of people seeking medical care outside their country of residence, it is estimated that the annual number in the United States alone has increased from 750,000 to 1.4 million over a 10-year period (2007 to 2017). This number is expected to increase by 25% each year, both in the United States and globally. The main motivations for seeking outsourced medical care include lower costs, avoiding long waiting lists, the ability to access procedures that are not available in the country of residence, and the ability to combine health care with a vacation stay. Procedures related to cosmetic and aesthetic surgery account for the largest percentage of procedure types, followed by organ transplants, cardiac surgery, dental procedures, cancer treatment, joint treatments, bariatric surgery, and assisted artificial insemination techniques.
This type of medical care can pose a risk to both public health and the life of the person receiving that type of care. Public health risks include the occurrence and spread of outbreaks caused by resistant microorganisms. As for the patient, the most common complications are surgical wound infections and bacterial sepsis.
The risk of health care in other countries is related to the following factors, among others:
People with chronic diseases who take daily medications are at higher risk for complications and death during a heat wave, as are the elderly, children, pregnant women and outdoor workers!
If you feel dizzy and weak, or have severe thirst and headache, go to a cool, shady place to rest and drink water or fruit juice. Seek medical attention if you experience unusual symptoms such as confusion or vomiting. If you develop painful muscle cramps or other symptoms such as a persistent headache, you should also seek medical attention.
Some symptoms of heat-related illness, such as high fever, headache, loss of appetite, dizziness, or shortness of breath, may resemble symptoms of other illnesses. If you or someone else is uncomfortable in hot weather with a high temperature, you should consider the possibility of motion sickness and/or heat-related illness
Health authorities in the Czech Republic report an increase in hepatitis E cases in the Moravian-Silesian region and throughout the country. In 2022, a total of 319 cases of hepatitis E were reported, and by the end of May 2023, 221 new cases had already been reported.
Doctors assume that it could be contamination from insufficiently cooked meat, especially pork.
Although monkeypox (MPOX) cases have declined significantly in recent months, it is important to remember that the virus is still circulating at low levels. Some WHO member states continue to report new cases, and the possibility of reintroduction, either from endemic areas or newly affected countries, is likely.
Based on the findings of the current outbreak and the low number of new infections, the overall risk for MPOX remains moderate for men who have sex with men and very low for the general population. However, ECDC has warned of the possibility of an increase in cases next summer due to a series of celebrations such as Pride events and increased travel.
To kick off the summer festival season and Pride month, ECDC is releasing an updated fact sheet for health professionals. In addition, ECDC and the WHO Regional Office for Europe have provided a series of new infographics and social media maps on personal protective measures to consider for those at increased risk.
MPOX is transmitted primarily through skin contact, including during sex, with someone who has Mpox, even before symptoms appear.
An increase in leishmaniasis cases in the north of the country has been reported in Honduras. In May of this year alone, 20 cases were registered. For the full year 2022, the number of cases was 84 (2021: 112 cases).
An increase in cutaneous leishmaniasis was also observed in Nicaragua in the first months of the year, with 306 cases.

The risk is low. People who are over 60 years of age, have an underlying disease, or have a weakened immune system are at higher risk for the more severe form of West Nile virus.
The following precautions are recommended:
If you have visited a West Nile fever transmission area, do not donate blood for at least 28 days after your return.
Formally, this means Algeria falls again under the WHO temporary polio vaccination recommendations (category 2: "States infected with cVDPV2, with potential or demonstrated risk of international spread"), confirmation by the IHR committee is still pending. Meaning: Persons staying in the country for > 4 weeks are strongly recommended to have a min. 4 weeks and a a max. 12 months old polio booster vaccination (IPV) with documentation in the international vaccination certificate when leaving Algeria. This is important to prevent the spread of poliomyelitis virus from the country and can be checked upon departure. Persons staying in the country for <4 weeks are recommended to have a booster vaccination every 10 years in addition to a basic polio immunization.
Preliminary analysis of samples revealed two positive Marburg virus cases. The two patients from the southern Ashanti region - both deceased and unrelated - presented symptoms of diarrhea, fever, nausea and vomiting. Preparations for a possible outbreak response are being made rapidly as further investigations are in progress.
Marburg is transmitted to humans by bats (fruit bats) and spreads in humans through direct contact with bodily fluids of infected persons, surfaces, and materials. The disease begins abruptly with high fever, severe headache and discomfort. Many patients develop severe hemorrhagic symptoms within seven days. Mortality rates have varied from 24% to 88% in previous outbreaks, depending on the strain of virus and case management.
Most of the laboratory-confirmed cases (2933/3413; 86%) were reported from the WHO European Region. In Switzerland, there have been 81 confirmed cases since May 21 and up to June 29.
Clinical presentation: The cases so far have been mild, there have been no deaths yet. Hospitalised patients have mostly been admitted for local isolation orders. The clinical picture is characterised by lesions that are atypical of the clinical picture in endemic countries. Currently, there are mainly very few, non-grouped, painless pustular lesions on the genitals, perianally and orally. Whether transmission occurs through genital secretions or primarily only through close skin-to-skin contact is not yet clear. The draining lymph nodes are sometimes massively swollen, and fever usually occurs for a few days. The general condition is often only slightly reduced.
Transmission: The virus can 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 7-17 days. Monkeypox is transmitted from infected animals through a bite or through direct contact with blood, body fluids or lesions of the infected animal. They can be transmitted to people who eat infected animals via abrasions in the mouth, source, NCDC.
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.
If the clinical picture is suggestive, individuals should also be isolated, tested, and screened for monkeypox.
MANDATORY REPORTING: In Switzerland, every suspected case must be reported within 2 hours to the respective cantonal doctor and to the FOPH (tel. +41 58 463 87 06)! Specialist laboratories, such as the Reference Laboratory for Imported Viral Diseases (HUG) or the Spiez Laboratory or the ZBS1 at the Robert Koch Institute (RKI; consiliary laboratory for smallpox), offer molecular diagnostics for the identification of monkeypox infections (material: crust or vesicular fluid).
Geosentinel requests confirmed and suspected cases to be reported at: geosennel@geosentinel.org
The risk is higher for the disabled, pregnant, already fragile, poor, displaced, homeless, children, elderly, and outdoor workers!
