Pakistan reported its latest polio case on Wednesday in Balochistan’s Chagai district, raising the national count for the year to 43, according to the Pakistan Polio Eradication Programme. Pakistan and Afghanistan are the only countries where polio remains endemic, and vaccination teams are frequently targeted by militants waging a campaign against security forces. On Monday, Pakistan launched a week-long vaccination campaign with the aim of immunising more than 45 million children under the age of five. “The Regional Reference Laboratory for Polio Eradication at the National Institute in of Health has confirmed the detection of the 43rd Wild Poliovirus Type-1 (WPV1) case in Pakistan,” the statement said.
