Polio eradication this week:

  • In response to the recent outbreak of circulating vaccine-derived poliovirus (cVDPV) in Madagascar, supplementary immunization activities are scheduled in December in high risk areas and across the entire country in January to stop transmission of the virus.


  • This week, the Centers for Disease Control and Prevention (CDC), USA, released a report marking 2 years during which type 3 wild poliovirus has not been detected anywhere in the world. While the CDC report concludes that WPV3 transmission has possibly been interrupted, continued sensitive surveillance is needed before a final conclusion on WPV3 eradication can be made.
