Islamabad, Sha'ban 17, 1436, Jun 4, 2015, SPA -- Pakistan has seen a large decrease in polio cases in the first half of the year after suffering the highest number of infections last year in more than a decade, dpa cited a health official as saying Thursday. So far this year only 25 new cases have been registered, an official of National Institute of Health told dpa on condition of anonymity. The country had recorded 306 cases in 2014, according to the official figures. The army last year launched offensives in the North Waziristan and Khyber tribal districts and has cleared large areas of militants who opposed polio vaccinations, making it possible for the government to vaccinate children which were left out for years. --SPA 13:17 LOCAL TIME 10:17 GMT www.spa.gov.sa/w
