A health information system used mainly in countries where professionally trained health workers are in short supply. Using standard case definitions for surveillance, the emphasis is on identifying gross manifestations of threats to health by asking lay reporters (community leaders, school teachers, etc.) to record and transmit information about such conditions as high fever with shivers and sweats, bloody diarrhea, fever with skin rash, watery diarrhea, and malnutrition. Usually only death reports are submitted, but epidemics are also reported, especially those of an unusual nature. See also verbal autopsy.
Subjects: Public Health and Epidemiology.
