Niger

Status: imported poliovirus

In January 2006, Niger was taken off the endemic country list, having successfully interrupted indigenous wild poliovirus transmission for a period of 12 months. Since that time, Niger has been subject to repeated polio importations, due to its proximity to northern Nigeria. In all instances, adherence to international outbreak response has prevented imported polioviruses from re-establishing themselves. The dramatic decrease in new cases in northern Nigeria in 2010 has had secondary benefits for Niger, as exposure to imported viruses has decreased. Nevertheless, cases have been reported in 2010. Niger will continue to be at particular risk of re-infection until all indigenous wild poliovirus transmission has been interrupted in Nigeria.

  

Polio campaign monitoring

  

Polio this week in West Africa

  • No new WPV1 cases have been reported in West Africa in 2014. The most recent WPV1 case in the region had onset of paralysis in Tahoua province, Niger, on 15 November 2012.
  • No new cases of cVDPV2 were reported this week. The last case of cVDPV2 had onset of paralysis in Niger on 11 July 2013.
  • Even as polio programme staff across West Africa support efforts to control the Ebola outbreak affecting the region, a large scale synchronized vaccination campaign has been rolled out in those countries not affected by Ebola. NIDs took place on 19-22 September in Benin, Burkina Faso, Côte d’Ivoire, Gambia, Ghana, Mali, Niger and Togo, and in Mauritania 20-23 September using trivalent OPV. NIDs in Guinea-Bissau will take place 27-30 September, also using trivalent OPV. Further NIDs are planned in Burkina Faso, Cape Verde, Côte d’Ivoire, Gambia, Ghana, Guinea-Bissau, Mali, Mauritania, Niger, Senegal and Togo on 31 October-2 November.
