The UK Health Security Agency has confirmed the presence of West Nile Virus in local mosquito populations for the first time. While the risk to the general public is currently considered very low, health officials are monitoring the situation closely. West Nile Virus, which can cause severe neurological diseases, has previously been detected in other parts of Europe but not in the UK. Authorities are emphasizing the importance of surveillance and preventive measures to mitigate potential outbreaks.
