Polio campaign updates.

Upto date information as at 1 December 2017

Principal polio focus: (Where surveillance and immunisation activities continue)

 One new WPV1 cases reported in Afghanistan. No WPV1 positive environmental samples were collected either in Pakistan or Afghanistan.  In Syria no cVDPV2 cases, nor any cVDPV2 positive environmental samples, were reported. (For positive environmental samples, the viral environmental presence lasts for 7-14 days.)


            2017 TO 28 November:            16 WPV1   80 cVDPV2

            2016 TO SAME TIME:               34 WPV1     4 cVDPV2

            2016 FULL YEAR:                    37 WPV1     7 cVDPV2 

For polio-free certification purposes the start date for WPV monitoring is that of the onset of paralysis. The most recent WPV1 cases by country with onset of paralysis were:

 ·       In Afghanistan – 5 November 2017 - or 3 weeks since the onset of polio.

o   11 cases in 2017 vs.12 cases at the same time in 2016.

o   Three WPV1 positive environmental samples were collected this week in Kandahar province, and one sample was collected in Kabul province.

·       In Pakistan - 21 August 2017 - 14 weeks since the onset of polio.

o   5 cases in 2017 vs.18 cases at the same time in 2016.

o   The round of NIDs scheduled for this week aims to reach about 37 million children to protect them from polio.  

·       In Nigeria – 21 August 2016 – or 66 weeks since the onset of polio.

o   No cases in 2017 vs. 4 cases at the same time in 2016.

o   Continues to implement the emergency response.

 The numbers of cases of cVDPV2 this year and the dates of onset of paralysis are:

 ·       In Syria – 9 September 2017 – or 12 weeks since the onset of polio.

o   70 cases in 2017 vs. no cases at the same time in 2016. Genetic sequencing puts the initial infection to before the switch from tOPV to bOPV.

o   Most of the cases had occurred before the outbreak response started. The bulk of the cases have been from Deir Ez-Zor governate. (Most from Mayadeen district and some in the Boukamal district.) Other cases have been from the Talabyad district in the Raqqa governate and the Tadmour district in the Homs governate.

o   Outbreak response teams continue to use IPV strategically to boost immunity. Additional vaccines are being prepositioned as part of ongoing contingency planning to ensure that the programme is able to respond quickly in areas where there has been recent evidence of virus transmission. Activities will be carried out when the security situation allows.

o   7,751 children were reported as vaccinated with IPV in Damascus (86% of the target), as part of a sub-national campaign aiming to reach children with bOPV and IPV. The campaign also reached > 14,000 children from five IDP camps in Hasakah governorate, hosting populations from Deir Ez-Zor. In Ein Eisa IDP camp, Raqqa governorate and Al-Arysha IDP camp in Hasakah governorate, orientation sessions on the reporting of AFP cases are being conducted..

·       In the DRC - 14 September 2017 or 11 weeks since the onset of polio

o   10 cases this year but the most recent case in Haut Lomami province was linked to the case on 27 July which was 18 weeks since the onset of polio.
