  • New on www.polioeradication.org: We join Dr Urs Herzog, polio eradicator, National PolioPlus Advocacy Advisor for Rotary Switzerland and polio survivor himself, as he explains the financial costs of the programme and why it is critical that we eradicate every last trace of the virus.
  • Summary of newly-reported viruses this week: Afghanistan: Three new wild poliovirus type 1 (WPV1) positive environmental samples have been reported, one collected from Kandahar, one from Hilmand, and one from Nangarhar provinces. Pakistan: Four new WPV1 positive environmental samples have been reported, three collected from Sindh province, and one from Khyber Pakhtunkhwa province. Democratic Republic of the Congo: Advance notifications have been received of five cases of circulating vaccine-derived poliovirus type 2 (cVDPV2). These will be confirmed in next week’s data reporting.

  • Nigeria continues to implement an emergency response to the detected WPV1 strain and circulating vaccine-derived poliovirus type 2 (cVDPV2) strains affecting the country (last detected in 2016).
  • The next round of sub-national immunization days are planned for late January.
  • Detection of polio cases in Nigeria underscores the risk posed by low-level undetected transmission. As part of the emergency response, subnational surveillance continues to be strengthened.

Lake Chad Basin

  • The detection of wild poliovirus type 1 (WPV1) (Borno state, Nigeria in 2016) and circulating vaccine-derived poliovirus type 2 (cVDPV2) (Borno and Sokoto states in 2016) continue to pose a risk to the neighbouring countries of the Lake Chad basin.
  • Emergency outbreak response efforts continue across the Lake Chad basin, together with activities to fill subnational surveillance gaps across the region.
  • These activities include efforts to vaccinate children at markets, in internally displaced persons camps, and at international borders.
  • Phase 3 of outbreak response is being launched in January 2018, taking into account the recommendations made during the November Outbreak Response Assessments for the countries and the Technical Advisory Group meeting in December. The objective is to maintain and improve the multi-national, regional outbreak response across the Lake Chad basin region, in particular improving operations, reach and surveillance among hard-to-reach areas and populations.
