West Nile virus (WNV) infections have long been recognised in Europe where there is routine surveillance for human and equine disease. There is no evidence of locally-acquired human cases of WNV in the UK to date, and as of June 2025 only 7 confirmed travel-associated cases have been reported since 2000.

In 2025, 2 samples of pooled Aedes vexans mosquitoes (collected in July 2023 from Nottinghamshire, England) tested positive for WNV. Modelling suggests that current UK temperatures are generally too low for inter-annual WNV transmission cycles to be established, but could permit some local short-term transmission where there are high numbers of infected mosquitoes, if they bite infected birds.
