PESHAWAR: Pakistan faces the single day worst shock over the Anti Polio Front.
Khyber Pakhtunkhwa on Saturday reported 13 new cases of polio, the highest number for the province in a single day, taking the nationwide toll to 25 in the current year.
According to the health department officials and Emergency Operation Centre (EOC) in Peshawar, the cases were mostly called circulating vaccine-derived poliovirus (cVDP2) or Type 2 polio.
Seven of the cases were reported from Khyber tribal district, while one case each was reported from Lakki Marwat, Bannu, Mardan, Nowshera, Bajaur and Lower Dir.
"Pakistan has this year reported 25 cVDP2 cases, in which Khyber Pakhtunkhwa alone had a share of 24," the report said.
“The reason of cVDPV2 outbreak is the result of a cohort of children without mucosal immunity to type 2 poliovirus.
The cVDPVs occurs when supplementary immunisation activities (SIAs)/polio rounds are poorly conducted and the population is left susceptible to poliovirus whether from vaccine-derived or wild poliovirus,” a senior public health specialist told *The News.*
