PESHAWAR, Pakistan — Pakistan efforts to eliminate polio suffered another blow on Monday after a northern enclave reported its first case in seven years. Overall, it was the country’s 11th case since January, despite the launch of several immunization drives. The virus was detected in a child from the district of Diamer in the Gilgit-Baltistan region, according to the country’s polio eradication program. Pakistan and neighboring Afghanistan remain the only two countries where the spread of the wild polio virus has not been stopped, according to the World Health Organization. There are ongoing outbreaks of polio linked to the oral vaccine in 10 other countries, mostly in Africa. The new case was reported after Pakistan on Sunday wrapped up its third nationwide polio vaccination drive of the year, aiming to immunize 45 million children. Mohammad Iqbal, a director at the polio program in the northwest, said local health officials were still trying to determine how the poliovirus that was found in the southern port city of Karachi had infected the child in Diamer. During the summer season, thousands of tourists from Karachi and elsewhere visit tourist resorts in Gilgit-Baltistan. Pakistan’s polio eradication program has been running anti-polio campaigns for years, though health workers and the police assigned to protect them are often targeted by militants who falsely claim the vaccination campaigns are a Western conspiracy to sterilize children. Since the 1990s, attacks on polio vaccination teams have killed more than 200 workers and security personnel.
