In developing countries, the risk of food shortage and epidemic outbreak is high. Yet, there are often no surveillance systems in place to detect early warning signs. Because they are dependable and easy-to-use, Argos terminals are used by many humanitarian aid programs to relay crucial information from remote areas. In Africa and the Middle East, Argos terminals are used to monitor school attendance and food distribution data. Argos terminals are also used for early detection and warning of communicable disease outbreaks (such as malaria, cholera...), by relaying information about case loads and drug availability from remote areas to health ministries. Information relayed by Argos allows local, national or international organizations to better monitor and manage aid programs and prevent humanitarian crises.
