Distribution of confirmed cases in Afghanistan 2008-11 and Area of 13 High Risk Districts Despite number of rounds poliovirus is isolated at regular intervals indicating continued circulation with a shift from P3 to P1 type in 2010 -11 Almost 80-90% of the confirmed cases reported from the 13 High Priority Districts. Target Population of these districts is 54% of the region and 9% of the Country .
AFP Cases with isolation of cVDPV2 reported during 2010-11 Southern Region Afghanistan Data up to 16 Mar 2011 Five cVDPV2 cases reported during Jun-Dec 2010 and one in 2011 Nad Ali Dist Helmand Almost 30-50 % of the target remain inaccessible in most of the rounds. SIAs coverage also ranged between 18-60% Routine vaccination coverage among AFP cases <24 months is 9% tOPV used in July SNIDs only in NadAli. An additional round with tOPV in 4 districts followed by tOPV in November NIDs. 3 rounds of accelerated routine EPI are planned in 2011. First round completed and 7700 children below 1 year vaccinated with tOPV. Guidance from TAG is requested Nimroz 2010 cVDPV2 2011 cVDPV2 Hilmand Kandahar Urozgan Zabul
Characteristics of polio cases 2010-11 Afghanistan
The Median age of all polio cases is 18 months ranging from (4-144)
The Median OPV dose of all confirmed polio cases is 4 while among non polio cases it is 13
14 out of 21cases in the southern provinces have not received OPV through routine while 8 cases have not received any OPV dose.
In 2010, 17 cases are of P1 type and 8 cases of P3 type. One case reported for 2011 is also P1 type
Genetic study of most cases reported from South are indicating indigenous circulation of the virus while cases reported from East, North East and the recent 2011 case from Kandahar matches closely with circulation across the border in Pakistan.
Data up to 16 Mar 2011
Cross border Epidemiological situation and Risks Afghanistan 2010-11
Continues circulation of virus in KPK Pakistan is posing great risk of virus transmission to the Eastern and Southeastern regions of the country
Polio outbreak in Tajikistan and transmission of virus to Afghanistan was another epidemiological risk during 2010
Transmission, High risk & non transmission zones Afghanistan 2011
South & Farah: with on going virus circulation
High Risk zone
East, South eastern regions: Risk of virus transmission from across the border
Non Transmission Zone :
Central , north , northeast. Western region: no evidence of established virus transmission.
Transmission High Risk Non-Transmission
