CDC: Nigeria has most of world's polio

ATLANTA (UPI) -- Nigeria had the world's highest burden of wild poliovirus in 2008, with 798 -- 48 percent -- of the 1,651 cases reported globally, U.S. health officials say.

The Centers for Disease Control and Prevention's Mortality and Morbidity Weekly Report said Thursday during 2008-09, Nigeria was the source of transmission of poliovirus to 13 nearby countries.

Despite increasing commitment by the government of Nigeria to eliminating wild poliovirus transmission and some indicators of progress, all three types of poliovirus are still being transmitted and resulting in paralytic disease among children.

However, with increased activities to interrupt wild poliovirus transmission during 2008, the number of type 1 wild poliovirus dropped substantially in the first seven months of 2009, as did the proportion of children who were reported to have never received oral polio vaccine.

But type 3 wild poliovirus cases rose and vaccine-derived poliovirus cases also increased, the report said.
