WHO has said that the two cases of the infection were reported from Federally Administered Tribal Areas (FATA) whereas a polio case was reported each from Khyber Pakhtunkhwa (KP) and Balochistan.
The total number of polio cases reported this year has risen to 266.
It should be noted that Pakistan is one of the only three countries in the world with polio infections. WHO and concerned anti-polio officials are active in eradicating the virus from the country whereas special immunization drives are also held on regular basis.
The country has also been slapped with travel restrictions due to the virus and the citizens have to travel with polio-free certificates to other countries.
However, attacks on polio teams and reluctance of parents to immunize their children are one of the major hurdles in eradicating the disease.
