Update: Polio this week – As of 24 July 2013
Global Polio Eradication Initiative
[Editor’s extract and bolded text]
:: In Nigeria, the Presidential Task Force has reviewed the latest epidemiology of poliovirus transmission and strategies to overcome remaining challenges. A new risk-classification system of low-performing areas aims to focus resources where they are most needed. See ‘Nigeria’ section for more.
:: In Pakistan, the outbreak in Federally Administered Tribal Areas (FATA) is continuing, with a new case reported from Khyber Agency. The current outbreak is threatening progress achieved elsewhere in the country, as well as efforts in neighbouring Afghanistan. See ‘Pakistan’ section
:: Five new WPV cases were reported in the past week (four WPV1s from Kano state and one WPV1 from Yobe state), bringing the total number of WPV1 cases for 2013 to 40. The most recent WPV1 case had onset of paralysis on 9 July (WPV1 from Kano)…
:: The latest epidemiology and strategies were discussed at last week’s Presidential Task Force meeting on 23 July in Abuja. The meeting underscored that more than half of this year’s cases are from two states: Borno and Yobe.
:: Performance during Immunization Plus Days (IPDs) continues to improve in all high-risk states. However, vaccination coverage gaps persist in low-performing Local Government Areas (LGAs), particularly in Kano, Borno and Yobe.
:: Although Borno and Yobe are affected by insecurity, polio eradication activities are continuing in most LGAs of Borno and all LGAs of Yobe. Special strategies are being evaluated for these areas, including conducting ‘wall fencing’ immunizations around insecure areas, use of permanent health teams and increased use of Short Interval Additional Dose (SIADs) campaigns, as and when opportunities arise. Social mobilization activities are being targeted, to increase community demand for polio vaccination.
:: Efforts must continue to improve micro planning, reaching ‘absent’ children, and further engaging communities and traditional leaders to address non-compliance.
:: At the same time, more needs to be done to foster subnational political engagement – the involvement of LGA Chairpersons remains inconsistent across high-risk states. Engagement at state-level is also inconsistent, as measured by the Abuja Commitments.
:: A new risk classification system will improve the delivery of resources to areas where they are most needed. Across the high-risk states, 129 LGAs have now been classified as ‘very very high risk’, ‘very high risk’, or ‘special situation’ (security-affected LGAs in Borno and Yobe).
:: The next subnational IPD in northern states is planned for early September using bivalent OPV. Measles vaccine will also be offered during this round.
:: One new WPV1 case was reported in the past week (WPV1 from Khyber Agency, Federally Administered Tribal Area – FATA), bringing the total number of WPV1 cases for 2013 to 22. It is the most recent WPV1 case in the country and had onset of paralysis on 3 July…
:: Federally Administered Tribal Areas (FATA) is the major WPV1 reservoir in Pakistan at the moment, accounting for 13 of this year’s 22 cases in the country. Khyber Agency is particularly affected, with nine cases, and in particular Bara tehsil of Khyber. This outbreak is threatening progress achieved elsewhere in the country and in neighbouring Afghanistan. In 2011 and 2012, Bara was the epicentre of a major outbreak which also spread to other areas.
Horn of Africa
:: 24 new WPV1 cases were reported in the past week (23 from Somalia and one from Kenya), bringing the total number of WPV1 cases in the region to 105 (95 from Somalia and ten from Kenya). The most recent case in the region had onset of paralysis on 10 July (from Somalia).
:: Eleven of the newly-reported cases are from Banadir, which remains the epicentre of the outbreak, accounting for more than half of all cases associated with this outbreak.
:: Four of the newly-reported cases are from Lower Shabelle, areas of which are inaccessible due to insecurity. Special strategies continue to be implemented for these areas, including increased local-level access negotiations, immunizing older age groups and setting up vaccination posts at entry/exit points of inaccessible areas.
:: In Somalia, nationwide campaigns were conducted last week, targeting children under the age of five years. In Kenya, SIAs are currently ongoing (27-30 July), aiming to reach host communities around the Dadaab camps…
