The weekly polio statistics from WHO (please dont post this publicly but please do know the statistics)... --- Dear colleagues, Please find attached this weeks global update slides as well as the weekly summary. Poliovirus Weekly Update 12-November-2014, World Health Organization Please scroll to the end for a summary of officially reported wild polio cases. New wild polio cases reported in the past week: 1 Total number of wild cases in 2013: 416 Total number of wild cases in 2014: 279 Headlines · In Madagascar, a circulating vaccine-derived poliovirus type 1 (cVDPV1) has been confirmed. The virus was isolated from one case of acute flaccid paralysis (AFP) with onset of paralysis on 29 September, and from three healthy contacts. An estimated more than 25% of children remain under-immunized against polio in the country. Madagascar was previously affected by a cVDPV2 outbreak in 2001/2002 (resulting in five cases) and in 2005 (resulting in three cases). Emergency outbreak response is being finalized, with campaigns to be held in December and January. · It has been two years since the last case due to wild poliovirus type 3 (WPV3) was reported. WPV3 was last detected globally on 10 November 2012, in Yobe, Nigeria. In Asia, the last WPV3 was detected in April 2012, in Khyber Agency, Federally Administered Tribal Areas (FATA), Pakistan. All cases due to wild poliovirus in the past two years have been caused by wild poliovirus type 1 (WPV1). Wild poliovirus type 2 (WPV2) has not been detected since 1999. Afghanistan § No new wild poliovirus type 1 (WPV1) cases were reported in the past week in Afghanistan. The total number of WPV1 cases for 2014 remains 18. The most recent WPV1 case had onset of paralysis on 4 October, from Kandahar province. § No new cases of type 2 circulating vaccine-derived poliovirus (cVDPV2) were reported in the past week. No cases of cVDPV2 have been reported in 2014. § Given the growing outbreak in neighbouring Pakistan, Afghanistan is taking protective steps to limit any spread of the virus. Subnational Immunization Days (SNIDs) are scheduled across the south and east of Afghanistan in mid- to late-November using a combination of bivalent oral polio vaccine (OPV) and inactivated polio vaccine (IPV). Nigeria § No new wild poliovirus type 1 (WPV1) cases were reported in the past week. Nigeria’s total case count for 2014 remains six. The most recent case had onset of paralysis on 24 July in Sumaila Local Government Area (LGA), southern Kano state. § No new type 2 circulating vaccine-derived poliovirus (cVDPV2) cases were reported in the past week. The total number of cVDPV2 cases for 2014 remains 21. The most recent cVDPV2 case had onset of paralysis on 12 September, from Katsina state. § Subnational Immunization Days (SNIDs) have been held 1-4 November in most areas of northern Nigeria using trivalent oral polio vaccine (OPV). In some areas of Kano and Yobe states, supplementary immunization activities using inactivated polio vaccine (IPV) and OPV are also taking place in November, with large-scale SNIDs planned for mid-December across northern Nigeria. Pakistan § One new wild poliovirus type 1 (WPV1) case was reported in the past week, from Khyber, Federally Administered Tribal Areas (FATA). The total number of WPV1 cases in 2014 is now 236, compared to 59 at this time last year. The most recent WPV1 case had onset of paralysis on 20 October, from South Waziristan, FATA. § No cases of type 2 circulating vaccine-derived poliovirus (cVDPV2) were reported in the past week. This most recent cVDPV2 case had onset of paralysis in Khyber Agency, FATA, on 16 September. The country has reported 20 cases of cVDPV2 in 2014. § Immunization activities are continuing with particular focus on known high-risk areas, in particular the newly opened areas of FATA. At exit and entry points of areas that are inaccessible during polio campaigns, 163 permanent vaccination points are being used to reach internally displaced families as they move in and out of the inaccessible area. Over 700,000 people have been vaccinated in the past few months at transit points and in host communities, including half a million children. Central Africa § No new wild poliovirus type 1 (WPV1) cases were reported this week. In 2014, 10 cases have been reported in central Africa: 5 in Cameroon and 5 in Equatorial Guinea. § Throughout November, supplementary immunization activities (SIAs) are being implemented across central Africa, with campaigns taking place in Equatorial Guinea, Central African Republic, Gabon, Chad, Republic of Congo, Angola and Democratic Republic of Congo (DR Congo). § In Cameroon, activities are planned for early December. During the most recent campaigns (31 October to 3 November), key improvements were noted. High levels of political engagement were evident, and preparations had focused on strengthening microplans and ensuring special vaccination teams at check points and border crossings. However, more improvements need to be made on ensuring missed areas are effectively re-visited, and ensure adequate number of vaccination teams for all areas are in place. Horn of Africa · No new wild poliovirus type 1 (WPV1) cases have been reported in the past week in the Horn of Africa. The most recent case, which had onset of paralysis on 11 August, was from Hobyo district of Mudug province, central Somalia. The total number of cases that have been reported in the Horn of Africa in 2014 is six: 1 WPV1 in Ethiopia (date of onset of paralysis on 5 January) and 5 WPV1s in Somalia. · Following confirmation of two cases of circulating vaccine derived poliovirus type 2 (cVDPV2) in South Sudan last week, outbreak response is being finalized in the country. National Immunization Days (NIDs) were already implemented on 4 November, with further campaigns planned for December and January. The objective is to rapidly stop the cVDPV2 in the infected area, while further boosting immunity to type 1 polio and minimize the risk of re-infection from other parts of the Horn of Africa. · Supplementary Immunization Activities (SIAs) in Djibouti, Ethiopia, Kenya, Somalia and Sudan, and Child Health Days (CHDs) with polio vaccines in Yemen are being held in November. Israel and West Bank and Gaza § Wild poliovirus type 1 (WPV1) has not been detected in environmental samples in Israel or the West Bank and Gaza Strip in recent months. The most recent positive sample was collected in southern Israel on 30 March. Environmental samples collected since April have been negative. Middle East § No new wild poliovirus type 1 (WPV1) cases were reported in the past week. Three cases of WPV1 have been reported in the Middle East in 2014 - two in Iraq and one in Syria. § It has been seven months since the last reported cases of WPV1 in the Middle East. The most recent case reported from Syria had onset of paralysis on 21 January, while the most recent case in Iraq occurred in Madain district, Baghdad-Resafa province, with onset of paralysis on 7 April. § Phase 2 of the Middle East Outbreak response continues to be implemented across the region, with focus on further improving the quality of supplementary immunization activities and to increase the reach of campaigns. West Africa § No wild poliovirus type 1 (WPV1) cases have been reported in West Africa in 2014. The most recent WPV1 case in the region occurred in Tahoua province, Niger, with onset of paralysis on 15 November 2012. § No new cases of type 2 circulating vaccine-derived poliovirus (cVDPV2) were reported this week. The last case of cVDPV2 was reported in Niger on 11 July 2013. § Even as polio programme staff across West Africa support efforts to control the Ebola outbreak affecting the region, efforts are being made in those countries not affected by Ebola to vaccinate children against polio. § National Immunization Days (NIDs) have taken place in Benin, Burkina Faso, Cape Verde, Côte d’Ivoire, Gambia, Ghana, Guinea Bissau, Mauritania, Senegal and Togo and Subnational Immunization Days (SNIDs) in Niger at the beginning of November.
