[Editor’s extract and bolded text]
:: Due to the Horn of Africa outbreak, the bulk of polio cases this year (over two-thirds) are in countries which were previously polio-free.
:: Between the endemic countries, cases are down 40% over the same period last year (78 compared to 131); this indicates progress particularly in Afghanistan and Nigeria, which are poised to enter the traditional ‘high season’ for polio transmission in a strong position. The subsequent ‘low season’ will be the most critical in the history of polio eradication.

Nigeria
::One new WPV1 case was reported in the past week (from Taraba), bringing the total number of WPV1 cases for 2013 to 46. It is the most recent WPV case in the country and had onset of paralysis on 17 August…

Pakistan
:: One new WPV1 case was reported in the past week (from Khyber Pakhtunkhwa – KP), bringing the total number of WPV1 cases for 2013 to 28. It is the most recent WPV case in the country and had onset of paralysis on 19 August.
:: FATA remains the major poliovirus reservoir in Pakistan and in Asia, both due to WPV1 and cVDPV2. Efforts are ongoing to curb transmission in this area, including through vaccination at transit points and conducting Short Interval Additional Dose (SIADs) campaigns in areas that have recently become accessible….

Horn of Africa
:: Four new WPV1 cases were reported in the past week, three from Somalia and one from Kenya. The total number of WPV1 cases for 2013 in the Horn of Africa is 179 (163 from Somalia, 14 from Kenya and one from Ethiopia). The most recent WPV1 case in the region had onset of paralysis on 7 August (from Somalia).
:: The Global Polio Eradication Initiative has conducted a three month assessment of the polio outbreaks in Somalia and Kenya. The assessment conclusions are 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, due to large numbers of under vaccinated children in Somalia and inconsistent campaign quality in Kenya. Outbreak response planning should therefore continue into 2014…
