Poliovirus detected in Tampere wastewater, but no cases reported

The Finnish Institute for Health and Welfare (THL) has identified a mutated type 2 poliovirus (VDPV2) in wastewater samples collected in the Tampere region in November. This strain, derived from an oral polio vaccine, is similar to findings reported in several European countries this autumn. Despite the detection, no cases of the disease have been identified, and Finland maintains high vaccination coverage against polio.
