Influenza of which the spreading over the island has never been well-researched is anticipated by a vaccination campaign organised in an empirical way after a model from the mother country (France). Dengue fever of which one of the vectors is omnipresent on the island ranged in an epidemic way in 1978. The aim of this network based on watching doctors, the laboratories of the island as well as the Pasteur Institute of Madagascar, is to adapt the prevention (Flu) and alert the Health Authorities in case of epidemic (Dengue).
