KARACHI: Wild Poliovirus Type-1 has been detected in the environmental samples from Peshawar and Sibi.

“The Regional Reference Laboratory for Polio Eradication at the National Institute of Health Islamabad has confirmed the detection of Type-1 Wild Poliovirus (WPV1) in two environmental (sewage) samples from districts Sibi and Peshawar,” an official in the PEI said.
