Shrinking the Malaria Map

UCSF Global Health Group’s Malaria Elimination Initiative (MEI)

Mayotte

Mayotte reported only 1 local malaria case in 2014 and is making remarkable progress towards elimination. 

Mayotte is part of the Comoros archipelago, located in the Indian Ocean between the island of Madagascar and Mozambique on the east coast of mainland Africa. Mayotte has been governed by France since 1841, and after gaining independence in 1975 along with the other Comoros islands, opted to remain an overseas department of France. The territory is made up of two islands, Mahoré and Pamanzi, and several small islets; the majority of the population lives along the coastline of Mahoré. While Mayotte’s malaria burden has always been relatively low, the territory has achieved a remarkable 99% decline in malaria cases since 2003, reporting just 1 local case in 2014. 

Mayotte has a humid, tropical climate with a rainy season from October to March. Malaria transmission occurs year-round and peaks during the rainy months. As a result of the increased pace of development in recent years, as well as the expansion of malaria control interventions, there are no longer any active transmission foci on Mayotte. In the past few years, cases have been concentrated in the northern part of Mahoré in the same areas where mosquito vectors re-emerged, near the capital of Mamoudzou where many Comoran migrants arrive. Mayotte’s malaria elimination strategies include free distribution of insecticide-treated nets (ITNs), indoor residual spraying (IRS) of dwellings, larval control, prompt treatment with free artemisinin-based combination therapies (ACTs), active case detection and case investigation, and mandatory reporting from the private sector. As a French territory, Mayotte has access to a high level of funding and sophisticated health services that are not available in other countries in the region, putting the island in an excellent position to achieve and sustain malaria elimination.
