The local Welfare and Health Authorities together with the country cou ncil of Reunion island set up a medical supervision network for influe nza and dengue fever in March 1996. Influenza of which the spreading o ver the island has never been well-researched is anticipated by a vacc ination campaign organised in an empirical way after a model from the mother country (France). Dengue fever of which one of the vectors is o mnipresent on the island raged 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 preven tion (Flu) and alert the Health Authorities in case of epidemic (Dengu e).
