According to the release, the total number of ADD cases reported in Chennai in the same period last year was 1920. The number of ADD cases reported by the 596 hospitals is 346 in August and 93 this month.

At least 2.1 tonnes of unwholesome food sold in the roadsides have been destroyed every week in all the zones by a rapid action team in coordination with Food Safety and Drug Administration Department. The Chennai Corporation has been closely monitoring all infectious diseases through a surveillance unit for the past four years.

Residents are advised to drink filtered, boiled water and avoid eating unwholesome food at the roadside, the release said.
