The number of wild polio cases for 2026 as of March 30th, 2026, is 2.
One in Pakistan and one in Afghanistan.
At this point last year, we had 9 cases.
The most recent confirmed case of Wild Polio occurred in Pakistan on February 10, 2026.
You may have seen a headline stating that Polio was detected in London in recent weeks. While that’s true, it was not Wild Polio, but rather circulating vaccine-derived poliovirus which is a weakened vaccine derived virus. It was detected during a routine sample taken from a sewage treatment plant and may have been excreted by someone who had received oral polio vaccine or had come into contact with someone who had. While uncommon, it’s not unheard of and underscores the need for communities to maintain high vaccination rates. Fortunately, there have been no reported cases of paralysis in the UK in recent years.
