West Nile Virus Detected in UK Mosquitoes

The UK Health Security Agency (UKHSA) has announced the first-time detection of West Nile virus fragments in UK mosquitoes. This discovery was made through a joint research program by the UKHSA and the Animal and Plant Health Agency (APHA).

Key Findings

• Genetic material of the virus found in mosquitoes collected in Britain in 2023.
• Aedes vexans mosquitoes were the species in which the fragments were found.

• Human transmission is rare but possible.

The UKHSA has stated that the risk to the general public remains "very low". Healthcare professionals will receive further guidance.
