Polio eradication this week:
- In central Africa, a new wild poliovirus type 1 (WPV1) case was reported in Equatorial Guinea. In total, 3 cases have now been reported from the country; genetic sequencing indicates the cases are linked to an ongoing WPV1 outbreak in Cameroon. Outbreak response in the country is currently being planned.
- On 17 March, WHO had elevated the risk assessment of international spread of polio from Cameroon to ‘very high’. The risk assessment was elevated due to: confirmation of additional WPV1 cases from three new regions of Cameroon confirming continued WPV transmission and geographic expansion of infected areas following detection of four cases in October 2013; gaps in surveillance; and, influx of vulnerable refugee populations from Central African Republic.
