Pakistan is moving closer to eradicating polio, officials said Tuesday, with no fresh traces of the crippling childhood disease found in sewage samples taken from 40 high-risk sites across the country over April.
“This is in line with our objective of eliminating polio by the end of the year,” said Rana Safdar, national coordinator of the Emergency Operation Center tasked with eliminating the disease which is endemic to Pakistan and neighboring Afghanistan.
He said 11 new polio cases have been recorded in humans since the start of the year compared to 25 in the same period in 2015, a year which itself saw an overall decline in incidents of the disease.
April was the first month since testing of sewage began that zero samples taken from 40 high-risk urban sites tested positive.
“It does not mean that we have cleaned the country of polio, but we have a lot of confidence that the intensity of the virus transmission has decreased to an all-time low,” said Safdar, adding the result was particularly important because it comes at the onset of summer when the virus is most contagious.
Attempts to eradicate polio in Pakistan have been hit by militant attacks on immunization teams that have claimed more than 100 lives since December 2012.
But Safdar said an improving security situation and efforts to educate communities who have traditionally been suspicious of vaccines has reduced the percentage of unvaccinated infants to “negligible,” against 5 percent in 2015 and 20 percent in 2014.
In addition to their normal campaigns, polio vaccination teams are concentrating their efforts in higher-risk zones, for example the militancy-wracked Pakistan-Afghanistan border region and Afghan refugee camps.
