According to the Global Polio Eradication Initiative (GPEI), two cases of cVDPV2 were reported in Haut Lomami province in the southern part of the country and two cases in Maniema province in the east-central region.

GPEI says outbreak response plans are currently being finalized, with supplementary immunization activities using monovalent oral polio vaccine type 2 (mOPV2) in line with internationally-agreed outbreak response protocols. Surveillance and immunization activities are being strengthened in neighboring countries.

DRC is also battling an Ebola Virus Disease (EVD) outbreak in Bas Uele Province in the north-east of the country.

In additional polio news, while the number of wild poliovirus (WPV) cases on the planet remain at 5 (3 in Afghanistan and 2 in Pakistan), eight environmental samples between the two countries tested positive for wild poliovirus type 1 (WPV1).
