Polio eradication this week:
- In June, the wild poliovirus outbreaks in Equatorial Guinea, Ethiopia and Kenya were assessed to be over by independent teams, having successfully interrupted transmission of the virus. It is essential for these gains to be maintained and built upon in order to protect children within these countries from the return of the virus. Read more on Equatorial Guinea, Ethiopia and Kenya.
- Five cases of circulating vaccine derived poliovirus type 1 (cVDPV1) have been reported in Madagascar, with dates of onset of paralysis in April and May 2015. These cases are genetically linked to that from September 2014, indicating prolonged and widespread circulation of the virus. The emergency outbreak response is now being intensified to build immunity against the virus in the country. Learn more about vaccine-derived polioviruses here.
