[Editor’s extract and bolded text]
:: Following confirmation of 24 new cases in the Horn of Africa last week, five more cases are confirmed this week, all from Somalia. See ‘Horn of Africa’ section for more.
:: In Pakistan, Federally Administered Tribal Areas (FATA) remains the major poliovirus reservoir in the country. Virus transmission in FATA is threatening progress achieved elsewhere in the country and in neighbouring Afghanistan. An analysis of vaccination status of non-polio acute flaccid paralysis (AFP) cases suggests that more than half of children in FATA remain under-immunized, with as many as 40% never having received a single dose of oral polio vaccine (OPV). See ‘Pakistan’ section for more.
:: In Israel, a supplementary immunization activity (SIA) with OPV is being conducted this week, targeting 200,000 children aged two months to ten years in the southern part of the country. The move follows isolation of wild poliovirus type 1 (WPV1) from sewage samples collected from 20 sampling sites since February. No cases of paralytic polio have been reported. While Israel has high vaccination coverage with inactivated polio vaccine (IPV), the objective of the OPV SIA is to boost mucosal immunity levels to rapidly interrupt virus circulation.
:: Two new WPV1 cases were reported in the past week (from Kano state), bringing the total number of WPV1 cases for 2013 to 42. One of the newly-reported cases is the most recent WPV1 in the country, with onset of paralysis on 14 July…
:: Following a new risk-classification of Local Government Areas (LGAs), aimed at improving the delivery of resources to areas where they are most needed, tailored approaches are being implemented in LGAs where performance has stalled, LGAs where performance has decreased and LGAs where access to populations is compromised due to insecurity.
:: Across all areas, strengthened efforts are being made to track the direct engagement and oversight by LGA Chairpersons.
:: The engagement of communities, and traditional and religious leaders, is continuing to be fostered. The Volunteer Community Mobilizer Network continues to be expanded, and social data analysis is expected to provide further understanding for children being chronically missed.
:: Operational plans for insecure areas feature the introduction of Permanent Health Teams (PHTs), conducting wall fencing vaccinations around insecure areas, expanding transit vaccinations, implementing Short Interval Additional Dose (SIAD) campaigns and engaging non-traditional partners…
:: …One new cVPDV2 case was reported in the past week, bringing the total number of cVDPV2 cases for 2013 to six. It is the most recent cVDPV2 case in the country and had onset of paralysis on 30 June (from North Waziristan, FATA – the third cVDPV2 in North Waziristan).
:: Two new positive environmental samples (WPV1) were confirmed, collected in early July from Peshawar, Khyber Pakhtunkhwa (KP) and Hyderabad, Sindh. In total, 24 environmental samples have tested positive for WPV1 in 2013 from various sites across Pakistan, the bulk from Peshawar (10) and Hyderabad (6).
:: In addition to this latest cVDPV2 case, North Waziristan is also affected by WPV1. It is an area where immunization campaigns have been suspended by local leaders since last June. To minimize the risk of a major WPV1 and/or cVDPV2 outbreak in this area, it is critical that access to children is granted as quickly as possible. Immunization campaigns in neighbouring high-risk areas are being intensified, to further boost population immunity levels in those areas and minimize the risk of further spread.
:: FATA remains the major poliovirus reservoir in Pakistan, both due to WPV1 and cVDPV2. Khyber Agency is particularly affected, accounting for 13 of this year’s 22 WPV1 cases in the country. Of six cVDPV2 cases in the country this year, three are from North Waziristan.
:: According to vaccination status of non-polio AFP cases, more than half of children in FATA are under-immunized, with as many as 40% never having received a single dose….
Horn of Africa
::Five new WPV1 cases were reported in the past week (all from Somalia), bringing the total number of WPV1 cases in the region to 110 (100 from Somalia and ten from Kenya). The most recent WPV1 case in the region had onset of paralysis on 10 July (from Somalia).
:: Two 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…
Israel Extends Polio Vaccination Campaign
JERUSALEM | Fri Aug 9, 2013 1:33pm EDT
(Reuters) – Israel will administer the active polio vaccine to children nationwide beginning on August 18, the Health Ministry said on Friday, stepping up an inoculation campaign currently limited to the south of the country.
The decision was made after the virus was detected in sewage treatment plants in Lod and Ramle, towns close to Israel’s central hub city of Tel Aviv, the ministry said in a statement.
It said it would call on parents of children born after January 2004 to bring them to publicly-funded clinics to receive oral drops of a weakened active virus vaccine between August 18 and 25.
A smaller-scale vaccination campaign has been under way since August 4 in the south, where the virus was discovered in sewage last month. The Health Ministry said 20 percent of children there had been inoculated since, and the number would increase to 50 percent within a week…
