According to a new global report on polio, Nigeria has made considerable progress toward polio eradication in the last 18 months. In the report published in the latest Morbidity and Mortality Weekly Report, MMWR, since late November 2013, no Wild PolioVirus 3 cases had been reported for more than a year.
The report also showed that the geographic extent of WPV transmission no longer includes the western states, and the number of WPV cases reported through September 2013 (49) was half of what was reported during the same period in 2012 when about 101 cases were reported.
It further explained that improvements in the quality of Supplemental Immunization Activities, backed by effective outbreak response still remain the key to interrupting wild polio virus transmission in Nigeria this year. However, the report maintained that despite these successes, continued WPV1 transmission in Nigeria was still a threat to global polio eradication and must be addressed urgently, particularly as the country enters the relatively low WPV transmission season (November-April).
