Yaounde - For the first time ever, a circulating variant poliovirus type 3 (cVDPV3) was fully sequenced in Cameroon, marking a major milestone in Africa’s efforts to detect and respond faster to polio outbreaks.
Poliovirus has three types: 1, 2, and 3. Although wild polio type 3 was declared eradicated in 2019, variant type 3 can still appear where immunity is low, making quick detection and response essential to contain outbreaks.
