Pakistan reported four additional wild poliovirus type 1 (WPV1) cases in the past week. The cases were reported from Bannu district in Khyber Pakhtunkhwa province (2); one from North Waziristan district in KPTD; and one from Larkana District in Sindh province, according to the Global Polio Eradication Initiative.
This brings the total WPV1 cases to 15 in Pakistan year-to-date and 22 total globally (Afghanistan has reported 7).
In addition, WHO received notification through the Global Polio Laboratory Network (GPLN) of the detection of wild poliovirus type 1 (WPV1) from an environmental sample from Sistan and Baluchestan Province in southeastern Iran.
The affected province borders both Baluchistan, Pakistan, and part of Southern Region, Afghanistan and genetic sequencing has confirmed that the isolated virus is linked to WPV1 circulating in Karachi, Pakistan.
The virus was detected in an environmental sample only – no associated cases of paralysis have been detected.
