The UK has identified West Nile virus in native mosquitoes for the first time, raising alarm over potential human infections. Experts call for increased vigilance and preparations for possible outbreaks as the virus, usually found in tropical regions, could indicate a broader change in public health risks. Although the overall risk to the public remains low, enhanced mosquito surveillance and control efforts are being implemented. Symptoms can occur in approximately one in five cases, prompting health officials to monitor the situation closely.
Reacting to the findings, virus experts have called for 'vigilance and investment in long-term preparedness' for potential outbreaks. 'This is a moment to recognise that the UK is no longer immune to some diseases once considered tropical,' said Professor James Logan, mosquito-borne disease specialist at the London School of Hygiene & Tropical Medicine (LSHTM).
Officials detected virus in samples taken from Aedes vexans mosquitoes, a native British species, from wetlands on the River Idle near the village of Gamston in Nottinghamshire.
