Surveillance and Notification System in Sivaganga District Dr. N. Ragupathy,M.D., Deputy Director of Health Services, Sivagangai.
Integrated Disease Surveillance Project ( IDSP) Integrated Disease Surveillance Project (IDSP) was launched by Hon’ble Union Minister of Health & Family Welfare in November 2004. It is a decentralized, State based Surveillance Program in the country. It is intended to detect early warning signals of impending outbreaks and help initiate an effective response in a timely manner
METHODOLOGY Under IDSP, data is collected on a weekly (Monday–Sunday) basis. The information is collected on three specified reporting formats, namely “S” (suspected cases), “P” (presumptive cases) and “L” (Laboratory confirmed cases) filled by the Health Workers, Clinician and Clinical Laboratory staff. The weekly data gives the time trends. Whenever there is a rising trend of illnesses in any area, it is investigated by the Medical Officers/Rapid Response Teams (RRT) to diagnose and control the outbreak
