The project name “MATE” (Monitoreo Argentino en Tele-Epidemiología) recalls a kind of herb tea which is very popular in Argentina. The MATE Project is supported by the CNES, the French Ministry of Foreign Affairs, the CONAE, and the Argentine Ministry of Health. Its goal for 2007 is to have the future human health user community (hospitals, vector control services, social welfare services) participate in the deployment of an operational network to control and predict the prevalence of dengue disease in Argentina. Beyond 2007, this project might be continued on a mutual cooperation basis with Brazil, Chile, Bolivia, and other neighboring countries pursuant to setting up an early warning network to control and predict dengue disease all over South America.
