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:
- Comoros requires travelers from Madagascar to present a medical certificate issued within five days prior to departure.
- Mauritius has classified Madagascar as a country at risk and has introduced enhanced passenger screening.
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.
- Avoid close, skin-to-skin contact with individuals who have, or may have, mpox, including anyone with a rash (pimples, blisters, scabs).
- Wash hands frequently with soap and water or use an alcohol-based hand sanitiser at least 60% alcohol).
- Avoid touching potentially contaminated personal items such as bedding, clothing, towels, cups, or eating utensils used by someone with suspected or confirmed mpox.
- Avoid sexual contact with sick people; use condoms for up to 12 weeks if your sexual partner has had mpox.
- Follow recommendations issued by local health authorities.
- For people belonging to an at-risk group, vaccination may be indicated. See Mpox factsheet.
- Avoid contact with 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.
