The interest of medication sales data in Syndromic Surveillance is well recognized. In France, where a real-time computerized surveillance system of frequent communicable diseases based on Sentinel general practitioners (SGPs) provides since 1984 a gold standard to evaluate other indicators, it has been shown that medication sales provided early alerts for influenza. Gastroenteritis surveillance relies in France on the surveillance of acute diarrhea by the SGPs in the general population, since 1991. The main objective of this study is to validate, at a national level, new indicators based on medication sales data to facilitate the detection of gastroenteritis epidemics.
Objective
This study examines how medication sales data can detect gastroenteritis epidemics in France.
