A crucial polio campaign to immunize more than 8.8 million children under the age of five against the paralyzing poliovirus has begun in 26 districts from Monday.
This polio outbreak response campaign is being held in 11 districts of Balochistan, seven districts of Sindh and five districts of Punjab after the detection of polio cases in Dera Bugti and Chaman and the detection of wild poliovirus type 1 (WPV1) in sewage samples of several districts of these provinces.
