Presence Of Poliovirus:
The World Health Organization (WHO) has identified the presence of poliovirus in multiple countries, including Pakistan, Cameroon, and several European nations.The research suggests that poliovirus may be primarily transmitted via the respiratory route rather than the traditionally assumed faecal-oral route.The resurgence of polio is evidenced by recent detections of both wild and vaccine-derived poliovirus in various countries.In 2024, Pakistan reported a total of 62 cases of wild poliovirus type 1 (WPV1).Environmental samples containing poliovirus have also been found in cities such as Barcelona, Warsaw, and Cologne (Germany), indicating potential undetected or unvaccinated populations at risk.
