Karachi- Another polio case surfaced in Karachi today, bringing the total number of cases in the country to 84 so far this year. One-year-old child, identified as Murad, is reportedly the latest victim of the crippling virus. The child is a resident of Landhi. Up till now 65 cases have been reported from the Federally Administered Tribal Areas (Fata), 12 from Khyber-Paktunkhwa (K-P) and now seven from Sindh. Pakistan is one of only three countries in the world where polio is still endemic but efforts to stamp out the crippling disease have been hit by repeated attacks on health teams.
