Polio eradication in the African Region: progress report
Abstract1. Polio eradication efforts in countries of the African Region suffered a major setback in 2003– 2005. During this period, wild poliovirus spread from the remaining endemic reservoir and reinfected 16 previously polio-free African countries. In 2004, the WHO Regional Committee for Africa adopted a resolution that called for the intensification of polio eradication activities in order to interrupt wild poliovirus transmission in the Region. 2. By the end of 2005, the number of endemic countries in the African Region had decreased from two (Niger and Nigeria) to one (Nigeria), while 12 countries that had suffered wild poliovirus importations in 2003–2005 had re-established their polio-free status. 3. Despite the progress made, there are still several challenges. There is high-intensity wild poliovirus transmission in northern Nigeria. The number of confirmed polio cases in Nigeria in the period January to June 2006 has more than doubled as compared to the same period in 2005. The country now accounts for over 80% of the 2006 global polio burden.
