Today, the laboratory has confirmed one new type-1 wild poliovirus case from Khyber agency in Federally Administered Tribal Areas (FATA). This brings the total number of polio cases country-wide in 2011 so far to 16 (all type-1). The total number of infected districts/tribal agencies remains nine.

Detailed epidemiological investigation of the new case and genetic analysis of the isolated polioviruse is under process. The available information about the new case is mentioned below.

Khyber Polio Case: 

Arif s/o Zufiqar is a 10-month old male child having onset of paralysis on 3rd March, 2011. The child resides in Village Hissara, Area Mastak, in tehsil Tirah. As per recall of the parents, the child has not received any dose of oral polio vaccine through SIAs or routine immunization. It is important to highlight the following:

  • The family of child is living in an area inaccessible for the vaccination teams since September 2009 and the reported child is related (cousin) to the last polio case reported from the same tehsil having onset of paralysis on 4th of February 2011.
  • Khyber agency has reported a total of six polio cases (all type-1) this year including two cases each from Tehsils Bara, Landi Kotal, and Tirah. The agency reported the highest number of polio cases (33; 25 type-1 and 8type-3) by any district//agency/town in 2010.
  • The Table (1) below illustrates inclusion of agency in a total of 11 vaccination campaigns since January 2010 all with the vaccine containing component against type-1 poliovirus.  However, persistently missing large number of children, upwards of 100,000 in eight campaigns has lead to overall very low coverage (adjusted).  
  • Of concern is the inconsistent campaign quality in the accessible areas as indicated by high proportion of areas below 90% finger marking coverage.
  • During January 2011 SNIDs, 21% of the areas had finger marking coverage below 95%, one of the targets set in the Provincial Emergency Plan for Polio Eradication-2011. In the recent most campaign in March, the Lot Quality Assurance Sampling Survey done was rejected at 80%, reinforcing quality issues in areas having no access issues.
