Polio this week as of 8 February 2017
As the low season for poliovirus transmission continues, the first wild poliovirus case from acute flaccid paralysis (AFP) in the calendar year 2017 is reported from Afghanistan. Wild poliovirus type 1 positive samples from 2017 had previously been reported from environmental samples in Pakistan. Both countries continue to intensify their eradication efforts to urgently interrupt any residual virus transmission.
Afghanistan’s long struggle to eradicate polio is showing strong signs that the country is closer than it has ever been to finally stopping the disease, once and for all.
The year 2016 ended with only 13 cases, down from 20 in 2015 and 28 in 2014. Notably, 99% of all districts ended the year polio-free, with transmission cornered in small geographical areas in the south, east and south-east of the country.
The importance of detecting type 2 polioviruses ‘post-switch’
3 February 2017 – In April 2016, the type 2 poliovirus component of trivalent oral polio vaccine (OPV) was successfully removed from routine immunization programmes around the world, through the globally-synchronized switch from trivalent to bivalent OPV (containing only type 1 and 3 serotypes). Since then, surveillance for type 2 polioviruses from any source globally has been intensified. Why is this important? And how significant is the detection of type 2 strain in a post-switch world?
