End Polio Now Position - 31st October 2017
Polio is an infectious, crippling and potentially fatal disease. There is no cure, but there are effective vaccines. The strategy to eradicate polio is based on preventing infection by immunising every child until transmission stops and the world is polio-free. The source of polio virus transmission is infectious humans but only 1 in 200 infections leads to irreversible paralysis. Of those paralysed, 5% to 10% die when their breathing muscles become immobilised.
Principal polio focus: (Where GPEI surveillance and immunisation activities continue)
The advanced notification of a WPV1 case in Afghanistan last week has been confirmed but another advanced notification of a WPV1 case there has been reported. This will not be shown in the records till next week. Meanwhile the WPV1 case count this year is now 13. Five more WPV1 positive environmental samples were collected, two in Pakistan and three in Afghanistan. These bring the total number of WPV1 positive samples collected in 2017 to 109. Two cVDPV2 cases were reported this week, one in the DRC and one in Syria. No cVDPV2 positive environmental samples were collected. The number of cVDPV2 cases in Syria is 53 and the total in the DRC is 10. (For positive environmental samples, the viral environmental presence lasts for 7-14 days.)
