Through ongoing surveillance, the Global Polio Eradication Initiative has received notification of the detection of circulating vaccine-derived poliovirus type 2 (cVDPV2) in Burundi and the Democratic Republic of the Congo (DRC) linked with the novel oral polio vaccine type 2 (nOPV2). The viruses were isolated from the stool samples of seven children with acute flaccid paralysis and from five environmental samples collected in Burundi. All reported isolates stem from two separate and new emergences of cVDPV2 linked with nOPV2 that originated in Tanganyika and South Kivu provinces in DRC.
