Addressing the Resurgence of wild Poliovirus Transmission in the African region: Information Document
Abstract1. In 1988, when the World Health Assembly adopted a resolution to eradicate polio, all countries in the African Region were polio-endemic. By the end of 2002, only two countries in the Region were polio-endemic. Since 2003, there has been a major increase in wild poliovirus transmission in the remaining endemic countries, with spill over into nine previously polio-free countries. 2. This resurgence in wild poliovirus transmission is attributed to a failure to vaccinate at least 90% of all susceptible children in the most endemic areas in Niger and Nigeria. Persistent gaps in the quality of supplemental immunization activities (SIAs) in these areas as well as the suspension of all immunization activities in Kano State, which is the epicentre of this transmission, have contributed to the current massive increase in wild poliovirus transmission in these areas. 3. To address the observed resurgence of wild poliovirus transmission in the African Region, efforts have been made to improve the quality of vaccination campaigns in Nigeria, while advocacy to ensure that Kano State resumes vaccination is being intensified. Several rounds of very high quality mop up vaccination campaigns have been conducted in the countries that experienced importations in 2003 and 2004.
