[Isolation of two African arboviruses from endemic mosquitoes in Madagascar]

The authors report the isolation of two african arboviruses, ArD 28542 and MMP 158, from Malagasy endemic Culicidae, Anopheles mascarensis and Aedes ambreensis. These isolations prove therefore, that viruses unknown to Madagascar to this day can reach these island and fit with the local natural environment, which is remarkable for its high degree of endemicity. The eventuality of introducing pathogenic viruses by the same way is discussed.
