ISLAMABAD (AP) — A Pakistani health official says a special anti-polio drive has been launched in Islamabad after traces of the virus were found in the city's sewage system.
The virus was detected weeks ago but so far no cases have been reported in Islamabad.
Dr. Rana Safdar, who coordinated Pakistan's polio eradication center, says the three-day vaccination campaign started on Monday. Safdar says police have taken steps to protect the polio workers.
The Taliban and other militants have in the past attacked vaccination centers and health workers because they perceive the vaccination drives as part of a Western conspiracy to sterilize Pakistani children or collect intelligence.
Pakistan is among a few countries in the world where polio is endemic. Islamabad registered its last polio case 10 years ago.
