One confirmed mpox case was detected in Mayotte on 08 Jan 2026 in a traveler arriving from Madagascar, where an mpox outbreak is ongoing.
In response, neighboring countries have implemented control measures:
Since 16 December 2025, Madagascar has reported approximately 100 suspected mpox cases and around 10 confirmed cases, with the Mahajanga coastal region in northwestern Madagascar remaining the outbreak epicenter.
Risk very low for general populations but moderate for at risk groups.
According to local media citing regional health director Dr. Seynabou Ndiaye, the Rift Valley fever (RVF) outbreak in Senegal’s Saint-Louis Region was declared over on 10 January 2026, with no patients remaining under surveillance.
The outbreak, declared on 21 September 2025, resulted in 360 confirmed cases from 5,196 tested samples, including 21 deaths (case fatality rate: ~5.8%). Nationwide, more than 500 confirmed human cases were reported by December 2025.
As of 8 January 2026, 18 villages in Pamekasan Regency, located on theMadura Island, East Java, Indonesia, were declared experiencing "Extraordinary Events" (KLB), with the highest suspected case counts in Proppo (193), Pamekasan (167), and Padmawaru (131).
In 2025, the regency reported 1’248 measles cases and 12 deaths, predominantly among children under five. Of 209 laboratory-confirmed cases, 78% were unvaccinated, while 22% had received only one dose. Also other regions in East Java reported outbreaks in 2025.
Measles spread quickly and can be dangerous - protection is simple: get vaccinated!
Swiss recommendations: All persons born after 1963 who have no documented protection against the infection (antibodies or 2 documented vaccinations) should be vaccinated twice with MMR vaccine at one month interval. In the event of an epidemic in the region or contact with a measles case, vaccination is recommended from the age of 6 months.
In 2025, Taiwan reported 477 confirmed acute hepatitis A cases, the highest annual total since 2017, including 447 local and 30 imported infections. Most cases were men (82.8%), primarily aged 30–39 (36.2%) and 20–29 (28.5%).
Case numbers rose sharply after March, with 50–65 new cases monthly from July to November, and nearly 40% of domestic cases were linked to intimate contact with infected individuals.
Vaccination against hepatitis A is recommended for all travelers to Taiwan.
Individuals at risk for hepatitis A, including men who have sex with men, should be vaccinated regardless of travel.
According to media, as of 6 January 2026, 76 suspected and six confirmed mpox cases have been reported across six regions: Boeny, Analamanga, Atsimo-Andrefana, Diana, Vakinankaratra, and Itasy. Reports do not indicate which clade has been detected.
This is the first mpox outbreak in Madagascar which was not listed among affected countries during the 2022–2023 global mpox outbreak, nor during the ongoing clade I activity reported in parts of Africa between 2023 and 2025.
Risk very low for general populations but moderate for at risk groups.
