Despite years of eradication campaigns, the wild poliovirus is rearing its head once again in Pakistan. 

Eight confirmed cases have been recorded so far this year – more than the entirety of 2023 – and wastewater samples have found traces of the virus in 46 districts, meaning it is spreading through communities undetected.

Reports of two children suffering paralysis have been announced on Friday by Pakistan’s health authorities, both under the age of three.

The disease was once widespread around the world – but is now endemic in just two countries – Pakistan and neighbouring Afghanistan.
