Via ABC News, an Associated Press report: Pakistan Says New Sampling Shows Progress Against Polio. Excerpt:
For the first time in Pakistan's history all the previous month's environmental samples for polio have tested negative — a sign of progress in the campaign to eradicate the virus, an official said Monday.
A total of 40 samples were collected from 14 cities in mid-April under the supervision of the World Health Organization and analyzed at the National Health Institute, said Dr. Rana Safdar, the head of the National Emergency Operation Center. WHO officials could not immediately be reached for comment.
Last year 22 percent of environmental samples tested positive, and 9 percent tested positive in the first quarter of 2016. Safdar said the negative samples represent a "significant achievement" but that complete eradication would require more "consistent efforts." He said new immunization campaigns have been planned in vulnerable areas starting in July, after the end of the Islamic fasting month of Ramadan.
