Poliomyelitis-related case-fatality ratio in India, 2002-2006.

Background: On the basis of studies from developed countries, the case-fatality ratio (CFR) of poliomyelitis generally ranges from 2%-5% among children <5 years of age to 10%-30% among adults. However, little information is available for poliomyelitis-related CFR in developing countries. We conducted a study to determine the CFR in India, 1 of the 4 remaining countries with endemic wild poliovirus (WPV) circulation, during outbreaks of WPV infection during 2002 and 2006 and during the inter-epidemic years of 2003-2005.
