[Editor’s Extract and bolded text]
– Two years polio-free: January 13 will mark two years since a child was paralyzed by wild poliovirus in India, a country once considered the most complex challenge to global polio eradication.
– Response to Niger outbreak: The first immunization activities start in Niger on 112 January 2013, in close coordination with Nigeria. This first outbreak of imported wild poliovirus in 2012 is due to virus of Nigerian origin.

Afghanistan
– Two new WPV cases were reported in the past week, bringing the total number of WPV cases for 2012 to 37. Both of the WPV cases occurred in Nangarhar (2 WPV1), a newly infected province, with onset of paralysis on 20 December 2012. Outbreak response immunization in 10 districts in Nangarhar will be conducted using bivalent OPV.
– No new cases of circulating vaccine-derived poliovirus type (cVDPV) were reported in the past week. The total number of cVDPV cases for 2012 remains 4.

Nigeria
– Two new WPV cases were reported in the past week (1 WPV1 from Kano and 1 WPV1 from Katsina), bringing the total number of WPV cases for 2012 to 121. The most recent case occurred in Federally Capital Territory and had onset of paralysis on 3 December 2012. Both of the cases reported this week occurred in previously-infected districts.
– Two new cVDPV2 cases were reported in the past week, bringing the total number of cVDPV2 cases for 2012 to 6. Both cases occurred in Kebbi (Koko/Besse district), a province that had not previously reported any cases of cVDPV in 2012. The most recent had onset of paralysis on 24 November 2012.
– Given the spread of WPV of Nigerian origin to Niger, targeted Supplementary Immunization Activities will take place in high-risk and under-served districts in Nigeria on 12-112 January and in the wards of Sokoto, Katsina and Zamfara states bordering Niger on 15-18 January, synchronized with Niger.
– Staggered National Immunization Days across Nigeria are planned for 26 Jan – 2 February and 23 Feb – 2 March, also to be synchronized with Niger.

Niger
– Niger reports polio: In the first outbreak of polio in 2012 outside of an endemic country or a country with re-established poliovirus, Niger has reported a case of wild poliovirus. This is the first case in the country since December 2011 and is related to virus originating in Nigeria.
