Pakistan’s National Polio Laboratory has confirmed the detection of Wild Poliovirus Type-1 in the sewage samples collected this month from Pishin, Balochistan and Peshawar, Khyber Pakhtunkhwa.
According to the laboratory, the Peshawar sample is connected to the virus detected in Nangarhar and that of Pishin to the virus in Kandahar, Afghanistan.
This is the 11th positive sample detected from district Peshawar this year, said an official.
Similarly, the other sewage sample was collected on September 04 from the neighbourhood of Turwa, Pishin district of Balochistan. It is the first positive sample from Balochistan province this year, said the official.
Meanwhile, the nationwide polio eradication campaign will kick-off from September 25 after polio virus was detected in environmental sites in different cities.
