The French Health Ministry recently reported that twelve cases of locally acquired malaria were recorded throughout the Mayotte Department in 2025. These are the first local cases since July 2020.
Additionally, 54 cases of imported malaria were recorded across the main island of Mayotte.
As of August 14, 2025, there have been a total of 66 cases of malaria reported in Mayotte this year.
Several imported cases, mainly from neighbouring countries in Africa, have been reported in previous years.
While available in Africa, malaria vaccines are not offered in Mayotte.
In addition to the this mosquito-borne disease, Mayotte has been significantly impacted by the Chikungunya virus in 2025. Both travel-related and locally acquired cases have been confirmed in all areas.
Unlike malaria, Chikungunya vaccines are approved and available in 2025.
These vaccines are needed in various Indian Ocean countries, such as Mauritius, Mayotte, Réunion, and Sri Lanka.
The U.S. CDC stated recently in a Level 2 Travel Health Advisory that, if eligible, Chikungunya vaccination is recommended before visiting outbreak areas in August 2025.
