Pakistan saw two additional cases of wild poliovirus type 1 (WPV1) in the past week, bringing the total in the country to six. According to the Global Polio Eradication Initiative, the new cases were reported from greater Karachi, Sindh (with onset of paralysis on 22 September) and Khyber district, FATA province (with onset of paralysis on 25 September).


This puts the total WPV1 cases reported in 2018 to 22, including 16 cases reported in Afghanistan this year.

In addition, four WPV1-positive environmental samples were reported in the past week, three from Khyber Pakhtunkhwa, collected between 18 and 27 September and one from Balochistan, collected on 1 October.

In Nigeria, one case of circulating vaccine-derived poliovirus type 2 (cVDPV2) was reported this week, from Katsina, with onset of paralysis on 16 September.  The total number of cVDPV2 cases in 2018 is 17.

Polio is a crippling and a potentially fatal infectious disease. There is no cure and the polio vaccine is the only safe and effective way to protect children.
