The National Institute of Health (NIH) said on Wednesday that four new environmental samples had tested positive for wild poliovirus type 1 (WPV1), bringing the total number of positive samples this year to 112.
The four new samples were collected from Karachi and Pishin district in Balochistan province and were genetically linked to the imported YB3A cluster of WPV1.
This cluster had been responsible for all positive samples and two human cases reported in Pakistan this year, private news channels reported.
