Status: affected by circulating vaccine-derived poliovirus

Circulation of vaccine-derived poliovirus type 1 (cVDPV1) has been confirmed in Indonesia. 

The detection of cVDPV1 underscores the importance of maintaining high routine vaccination coverage everywhere to minimize the risk and consequences of any poliovirus circulation as well as the need to ensure quality surveillance for early detection of any polioviruses. These events also underscore the risk posed by any low-level transmission of the virus. A robust outbreak response is needed to rapidly stop circulation and ensure sufficient vaccination coverage in the affected areas to prevent similar outbreaks in the future. WHO will continue to evaluate the epidemiological situation and outbreak response measures being implemented.
