Karachi recorded another case of polio in an 18-month-old boy resident of the city’s most volatile Gadap town neighborhood, officials confirmed today. He said that the child, identified as Ayaz Rasool, settled in Gadap town’s highly sensitive union council-4. Official said the boy had been inoculated only once in a special polio campaign carried out by the government, adding that his immunity and a lack of backup boosters led to the severe attack of the crippling disease on his frail body. “The report suggests the virus attack had affected all his four limbs,” said the official.

The NIT sources said that FATA where anti-polio immunization campaign was banned by militants have highest polio cases of 38 since Jan 01, 2014 while seven polio cases were reported in Khyber Pakhtunkhwa (KP) and five in Karachi.
