Status: endemic

In Pakistan, persistent wild poliovirus transmission is restricted to three groups of districts: (1) Karachi city, (2) a group of districts in Balochistan Province, and (3) districts in the Federally Administered Tribal Areas (FATA) and the Khyber Pakhtunkhwa. In addition, Pakistan and neighboring Afghanistan repeatedly re-infect one other, due to the substantial population movements within and between the countries.

Polio this week in Pakistan

  • Four new WPV1 cases were reported this week including two from South Waziristan, Federally Administered Tribal Areas – FATA, one from Bannu district, Khyber Pakhtunkhwa (KP), and one from Karachi (Khiorangi), Sindh, bringing the total number of cases for 2014 to 47. The most recent reported case had onset of paralysis on 30 March from Khiorangi, previously a polio-free district.
  • No new cVDPV2 cases were reported in the past week. The most recent cVDPV case had an onset of paralysis 8 March, from North Waziristan, FATA. The total number of cVDPV2 cases is 45 for 2013, and seven for 2014.
  • North Waziristan is the district with the largest number of children being paralyzed by poliovirus in the world (both wild and cVDPV2). Immunization activities have been suspended by local leaders since June 2012. It is critical that children in all areas are vaccinated and protected from poliovirus. Immunizations in neighboring high-risk areas are being intensified, to further boost population immunity levels in those areas and prevent further spread of this outbreak.
  • The densely populated Peshawar valley is considered to be the main 'engine' of poliovirus transmission, alongside North Waziristan, due to large-scale population movements through Peshawar from across this region, and into other areas of Pakistan. The quality of operations must be urgently improved in Peshawar, and immunization activities urgently resumed in North Waziristan.
