[Editor’s extract and bolded text]
:: The Global Polio Eradication Initiative has conducted a three month assessment of the responses to the Somalia and Kenya polio outbreaks, which concluded that the response was rapid and aggressive, with strong national leadership and international coordination.
:: In both countries, there is a significant risk that the outbreak will extend beyond six months. However, there are indications that the response activities to date are having an impact: fewer cases are being reported in the area considered the ‘engine’ of the outbreak – the Banadir region of Somalia, which includes Mogadishu. Concrete recommendations were made to ensure that the outbreak is stopped rapidly.

Nigeria
:: Two new WPV cases were reported in the past week, bringing the total of WPV1 cases for 2013 to 45. The most recent WPV1 case in the country had onset of paralysis on 14 August (from Borno)…

Pakistan
:: Two new cases of WPV were reported in the past week, both WPV1 from North Waziristan in the Federally Administered Tribal Areas (FATA), with the most recent case having onset of paralysis on 11 August. This brings the total number of WPV1 cases for 2013 to 27.
:: North Waziristan is one of the tribal agencies where a ban is in place against polio vaccination. Measures to prevent spread of the virus from this area include vaccination at transit points. FATA remains the major poliovirus reservoir in Pakistan and in Asia, both due to WPV1 and cVDPV2.

Horn of Africa
:: 32 new WPV1 cases were reported in the past week, in Somalia. The total number of WPV1 cases for 2013 in the Horn of Africa is 174 (160 from Somalia, 13 from Kenya, 1 from Ethiopia). The most recent WPV1 case in the region had onset of paralysis on 7 August (from Somalia).

Israel and West Bank and Gaza
:: WPV1 has been detected in 91 sewage samples from 27 sampling sites in Israel, collected from 3 February to 25 August 2013, indicating widespread transmission throughout the country. :: A sampling site in Tulkarem in the West Bank has reported one positive sample, collected on 30 June. No case of paralytic polio has been reported in either Israel or The West Bank and Gaza.
:: To interrupt WPV1 transmission, a supplementary immunization activity (SIA) with bivalent oral polio vaccine (OPV) targeting children up to the age of nine years is taking place. The activity started on 05 August in southern Israel and was expanded to cover the entire country beginning on 18 August. The objective of the SIA with OPV is to boost intestinal immunity in children vaccinated with Inactivated Polio Vaccine (IPV) only in order to rapidly interrupt WPV transmission.
:: Following the positive sample from Tulkarem, West Bank subsequent samples in the West Bank have all tested negative. Discussions continue on a vaccination response to the positive sample in the West Bank, which uses both OPV and IPV in its routine immunization schedule.
