Surveillance in leprosy forms an integral part of leprosy control activities. Usually contact and school surveys are done annually and general population surveys are done once every 3-5 years. Data is presented which suggest that frequently done surveys may not be cost effective as a means of case detection. Carefully done general surveys once every 3 years, covering contacts as well as school children may be adequate and more cost effective in endemic areas, whereas contact surveys, surveys of high risk groups and contact tracing, may be more relevent in low endemic areas.
