Pakistan has struggled to cope with the spread of polio, a debilitating viral disease. Human infections are frequently reported despite government and international agencies’ efforts to eliminate the disease. According to a World Health Organization (WHO) estimate, at least 72 polio cases were recorded in Pakistan in 2013, compared to 58 cases in 2012. In 2014, the number of infected children had already reached 115 through August. The most affected provinces of Pakistan are Punjab, Sindh, and Khyber-Pakhtunkhwa (KP).
