While we are in the middle of the endgame strategy to end polio, wild polio virus cases are still occurring in the border area between Afghanistan and Pakistan. We pass along weekly updates from the Global Polio Eradication Initiative on this site, click Read more... below.
Polio this week as of 30 October 2018
 
 
 
Headlines
  • World Polio Day activities garnered global attention. Partners, donors, and popular public figures around the world brought attention to the cause of polio and the efforts to eradicate polio. A quick overview of some of the World Polio Day highlights
  • Summary of new viruses this week: Afghanistan – Three new cases of wild poliovirus (WPV1) and four WPV1 positive environmental samples. Pakistan – No new case of wild poliovirus (WPV1) and seven WPV1 positive environmental samples. Papua New Guinea – three new cases of circulating vaccine-derived poliovirus type 1 (cVDPV1) and three cVDPV1 positive environmental samples. Democratic Republic of Congo – one new case of circulating vaccine-derived poliovirus type 2 (cVDPV2). Nigeria- two new cases of circulating vaccine-derived poliovirus type 2 (cVDPV2). Somalia- four new cVDPV2 positive environmental samples. See country sections below for more details.
  • Featured on polioeradication.org: Coffee with Polio Experts – Dr Arlene King, Chair of the RCC for the Americas, and GCC Containment Working Group talks to WHO about the importance of safe and secure containment of polioviruses, in places where needed, and the accompanying risk and responsibility that come with retaining the pathogen.
 Afghanistan:  
  • Three new cases of wild poliovirus type 1 (WPV1) have been reported from Maywand district, Kandahar province, from Pornus district, Nuristan province, and from Nawzad district, Hilmand province with onset of paralysis on 24, 26 September and 2 October respectively. This brings the total number of WPV1 cases in 2018 in the country to 19.
  • Four WPV1-positive environmental samples were reported, one from Hilmand province, collected on 25 September and three from Kandahar province, all collected on 3 October.
  • Nominal variations (up or down) in the number of newly-reported cases at this point of the polio endgame – although tragic for the affected children and their families – are not operationally overwhelming, especially considering the population size in the 3 remaining endemic countries (upwards of 90 million children aged less than five years).  However, confirmation of even a single polio case anywhere points to remaining vaccination coverage gaps which must be filled, to achieve eradication.
  • Over and beyond case numbers, the GPEI and its partners actively and continuously evaluate a wide range of epidemiological, virological, programmatic, operational, surveillance, financial and social data, the analysis of which drives strategic planning and enables target eradication efforts.
 Pakistan:
  • No new case of wild poliovirus type 1 (WPV1) has been reported this week. The total number of WPV1 cases in 2018 in the country remains six.
  • Seven positive WPV1 environmental samples have been reported across Pakistan: two in Rawalpindi district, Punjab province; two in Lahore district, Punjab province; one in Peshawar district, Khyber Pakhtunkhwa province; one in Gadap Town, Karachi district, Sindh province, and in Islamabad, Federal Capital Territory, collected from 10 to 11 October
  • It is important to note that cases are reported this year from only 4 districts across the country, and that no WPV cases (except one from Gadap, greater Karachi) have been reported from core reservoir areas in 2018.  20 years ago, the entirely country was affected by polio, and every year, more than 35,000 children were paralysed for life by the disease.
  Nigeria:
  • Two new cases of circulating vaccine-derived poliovirus type 2 (cVDPV2) cases were reported this week: one from Daura LGA, Katsina state with onset of paralysis on 18 September and one from Monguno LGA, Borno state, with onset of paralysis on 25 September . The total number of cVDPV2 cases reported in Nigeria in 2018 is 19.
  • No new cases of wild poliovirus type 1 (WPV1) were reported. The most recently-detected WPV1 case, from Borno state, had onset of paralysis on 21 August 2016.
  • The 36th Expert Review Committee for Polio Eradication and Routine Immunization (ERC), the independent technical advisory group in the country, met in Abuja on 29-30 October to review the evolving epidemiology and programmatic implications.  The group concluded:  Nigeria must maintain momentum by focusing on the remaining inaccessible areas through high quality (above 90% coverage) Supplementary Immunization Activities (SIAs) to prevent cVDPV2 outbreaks and reach the last remaining 70,000 children in Borno. A complete updated risk assessment of Kano state-it is likely to be infected- in the next mOPV2 rounds. Properly document the use of intradermal fractional dose of IPV (fIPV) in November since it is the first experience of fIPV use in AFRO.
  • The country continues to be affected by two separate cVDPV2 outbreaks, the first centered in Jigawa state, and the second in Sokoto state.
