[Malaria in the Comoros Archipelago in 2015: status after 15 years of fight]

The four volcanic islands of the Comoros archipelago are an area of intense, stable and permanent malaria transmission, almost exclusively with Plasmodium falciparum. Our purpose is to describe the current situation on malaria in Mayotte and Comoros in 2015, after the implementation of various strategies of control during the past 15 years. In 2015, Mayotte is in the phase of elimination of malaria. In the three islands forming the Union of Comoros, the transmission is much lower in the islands of Anjouan (incidence of 0.02‰) and Moheli (incidence of 0.14‰), ranking the two islands in pre-elimination phase. Grande Comore (incidence of 3.68‰) remains in the control phase with not enough time to assess what the mass treatment campaign long-term effects might be. These strategies could be applied in other islands with endemic malaria and with limited population.
