– No WPV3 has been reported from Pakistan in more than 12 months. The most recent WPV3 dates to 18 April 2012, from Khyber Agency in Federally Administered Tribal Areas (FATA). However, subnational surveillance gaps remain in FATA, and undetected circulation cannot be ruled out. As part of the national emergency action plan, efforts are ongoing to strengthen surveillance sensitivity, particularly in FATA which has seen a decline in reporting of acute flaccid paralysis (AFP) cases over the past 12 months.

Afghanistan
– One new WPV case was reported in the past week, bringing the total number of WPV cases for 2013 to two. It is the most recent WPV case, and had onset of paralysis on 28 March (WPV1 from Kunar).

Nigeria
– Two new WPV cases were reported in the past week (WPV1s from Borno and Niger), bringing the total number of WPV cases for 2013 to 14. The new case from Borno is the most recent WPV case in the country, with onset of paralysis on 28 March.

Pakistan
– The security situation continues to be monitored closely, in consultation with law enforcement agencies. Immunization activities continue to be implemented, in some areas staggered or postponed, depending on the security situation at the local level.

Horn of Africa
– Outbreak response is continuing in various parts of the Horn of Africa, in response to the ongoing cVDPV2 outbreak in south-central Somalia. Somalia conducted subnational activities on 26-29 March, and South Sudan conducted campaigns on 19-22 March. Further activities are planned in the second half of April.
