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:
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.

Regular hand washing after using the bathroom and before eating or preparing food. Avoidance of undercooked or raw food that is potentially contaminated with fecal material.
The most important prevention is vaccination. A very effective and well-tolerated vaccine against polio is available (inactivated (killed) polio vaccine (IPV)), which is part of the basic vaccination schedule during childhood. Combination vaccines (e.g. with diphtheria and tetanus) are also available. After basic vaccination, a booster dose is recommended every 10 years for travel to certain countries (see country page recommendations). WHO recommends a yearly vaccination for residents or long-stay visitors (minimum 4 weeks) in a country with ongoing polio infections or circulating vaccine-derived polio viruses. This recommendation not only targets individual protection, but aims to prevent the international spread of the virus.
Non esiste un trattamento specifico contro la malattia causata dal virus della rabbia.
Misure post-esposizione: Pulizia immediata della ferita con abbondante acqua e sapone per 10-15 minuti, seguita da disinfezione (ad es. Betadine, Merfen) e vaccinazione post-esposizione d'emergenza nell’ospedale più vicino entro 24 ore. È inoltre raccomandata la vaccinazione di richiamo contro il tetano se non è aggiornata. Per coloro che hanno ricevuto la vaccinazione antirabbica completa pre-esposizione prima del viaggio, sono sufficienti due dosi aggiuntive di un vaccino contro la rabbia (di qualsiasi marca) a un intervallo di 3 giorni. Se non è stata effettuata la vaccinazione completa pre-esposizione, oltre alla vaccinazione è necessaria l'immunizzazione passiva con immunoglobuline. Va notato che le immunoglobuline (e a volte i vaccini) spesso non sono disponibili in ambienti con scarse risorse, causando stress e incertezza.
È consigliato evitare di accarezzare animali domestici e di astenersi dal toccare animali selvatici, non familiari o morti.
Tutti i viaggiatori che si recano verso luoghi in cui la rabbia terrestre può manifestarsi e/o che probabilmente faranno viaggi ripetuti in zone in cui la rabbia è presente dovrebbero sottoporsi alla vaccinazione pre-esposizione. Inoltre, la vaccinazione pre-esposizione è altamente raccomandata per i viaggiatori particolarmente a rischio:
Lo schema di vaccinazione abbreviato può essere proposto alla maggior parte dei viaggiatori: 2 vaccinazioni, la prima possibilmente un mese prima della partenza (minimo 8 giorni prima della partenza). Una terza vaccinazione di richiamo per la rabbia è raccomandata prima del viaggio successivo, con un intervallo almeno di un anno.
There is a risk of arthropod-borne diseases other than malaria, dengue, chikungunya or zika in sub-/tropical regions, and some areas of Southern Europe. These include the following diseases [and their vectors]:
