Background: Despite the fact that wild poliovirus (WPV) circulation has not been detected for the past six years, cases of poliomyelitis caused by pathogenic circulating vaccine-derived polioviruses (cVDPVs) have been identified in the Democratic Republic of Congo (DRC). Most cVDPVs implicated in polio outbreaks are recombinants between mutated strains of the oral poliovaccine (OPV) and other human enteroviruses (HEV) of species C (HEV-C).The aim of this study was to determine the disease trend and the genetic makeup of cVDPVs strains isolated in DRC from 2008 to 2016.
