Health authorities in Burundi today declared an outbreak of circulating poliovirus type 2 (CVDPV 2) after confirming eight polioviruses, the first such detection in more than three decades. The cases were confirmed in a four-year-old child in Isale district in western Burundi who had not received any polio vaccination, as well as in two other children who were contacts of the four-year-old boy. Additionally, five samples from environmental surveillance of wastewater confirmed the presence of the circulating poliovirus type 2. “The detection of the circulating poliovirus type 2 shows the effectiveness of the country’s disease surveillance. Polio is highly infectious and timely action is critical in protecting children through effective vaccination,” said Dr Matshidiso Moeti, World Health Organization (WHO) Regional Director for Africa. “We are supporting the national efforts to ramp up polio vaccination to ensure that no child is missed and faces no risk of polio’s debilitating impact.”
