Europe sees record West Nile Virus cases as disease moves north

Europe has recorded its highest-ever number of locally acquired West Nile Virus infections, with 1,715 cases so far this year, up from 989 at the same point last year. Italy has been hit hardest, accounting for 748 cases and 56 of the continent's 130 deaths. Greece follows with 445 cases, then France with 144 and Spain with 139.

European health authorities link the surge to climate change, as rising temperatures push the mosquito-borne illness into new territories. This year, Belgium reported its first-ever locally acquired infections, with 15 cases, while the Netherlands recorded 59. The virus, first identified in Uganda in 1937, is in the same family as dengue and yellow fever.

While most infections cause flu-like symptoms, around one in 150 can develop into a severe and potentially fatal neurological disease. The UK has yet to see a locally acquired case, but its Health Security Agency warns that the risk is increasing.
