Polio this week as of 10 April 2018
 
Headlines:  New on www.polioeradication.org: Bill Gates and Aliko Dangote support polio eradication efforts in Nigeria. We talk with Professor Rose Leke, Chair of the African Regional Certification Commission, and with Dr Ondrej Mach, who explains why we are developing new polio vaccines for the post-eradication era.
   The report following the February meeting of the Global Commission for Certification of Poliomyelitis Eradication (GCC) is now published and available here. The GCC came together to review the criteria that will need to be met to achieve global certification of eradication.
   In Kenya, advance notification of a circulating vaccine-derived poliovirus type 2 (cVPDV2) detected from an environmental sample is being investigated (to be officially reflected in next week’s global data). A cVDPV2 was isolated from an environmental sample collected on 21 March 2018 from Nairobi, linked to the cVDPV2 confirmed from Mogadishu, Somalia. No cases of paralysis associated with this virus have been detected, however a risk assessment is ongoing as is planning for a potential regional response.
