While Pakistan has reported a sixth case of polio during the current year, 20 more environmental samples have tested positive for the virus of crippling disease.
A nine-month-old female child has been paralysed by poliovirus, bringing the number of cases reported this year to six.
The Regional Reference Laboratory for Polio Eradication at the National Institute of Health (NIH) has notified that the virus was detected in a nine-month-old child from Orakzai district.
“I am deeply saddened that this virus has robbed yet another child of the opportunity to live a healthy life and to live up to its potential,” said Federal Minister for Health Dr Nadeem Jan.
