[Editor’s Extract]
– This week, immunization campaigns are being implemented in all three remaining endemic countries, Nigeria, Pakistan and Afghanistan. Focus continues to be on urgently boosting immunity levels in known high-risk areas.

Afghanistan
– Three new WPV cases were reported in the past week (one WPV1 from Kandahar and two WPV1s from Hilmand), bringing the total number of WPV cases for 2012 to 30. The WPV1 from Kandahar is the most recent case in the country and had onset of paralysis on 28 October.
– Supplementary immunization activities (SIAs) are taking place this week (19-21 November), with the next activity planned for 01-06 December.
– The current campaign is being conducted in border areas with Pakistan, and uses a combination of trivalent OPV and bivalent OPV (depending on the area, in response either to recent WPV1 cases in the area, or to detection of a circulating vaccine-derived poliovirus type 2 outbreak – cVDPV2 – across the border in Pakistan).
– The Technical Advisory Group (TAG) is meeting next week in Kabul, to review the impact of the national polio emergency action plan and discuss additional tactics to address on-going immunity gaps in known high-risk districts.

Nigeria
– Four new WPV cases were reported in the past week (one WPV1 each from Jigawa, Kaduna, Kano and Katsina), bringing the total number of WPV cases for 2012 to 104. The WPV1 from Kaduna is the most recent case in the country and had onset of paralysis on 30 October.

Horn of Africa
– Efforts are continuing to stop an ongoing cVDPV2 outbreak in Kenya and parts of Somalia (in a Somali refugee camp in Dadaab, Kenya, and Kismayo, south-central Somalia).
– Immunizations of older age groups have taken place in Dadaab. In Somalia, campaigns have been conducted in border areas with Kenya and Ethiopia, and in some areas of central Somalia (access allowing).
