'Hitchhiking' mosquitoes that can transmit dengue and Zika virus found breeding in UK

UKHSA said control measures and enhanced surveillance are underway after larvae were found in several homes, with the public risk still very low.

  • On Thursday, the Health Security Agency reported the first confirmed instance of Aedes aegypti mosquitoes breeding in the UK, discovering adults and larvae at residential properties in east London.
  • It is the fourth detection of Aedes in recent years, as the species is known to "hitchhike" in imported plants, baggage, and vehicles, though this marks the first time they have bred locally.
  • Dr. Jolyon Medlock, Head of Medical Entomology at UKHSA, assessed the public health risk as "very low," noting that the broader UK climate remains too cold for the species to establish long-term.
  • Health officials are conducting enhanced surveillance and trapping to eradicate the infestation, while stressing as a "precaution" that Londoners should remove standing water from outdoor spaces to prevent breeding opportunities.
  • Monitoring efforts continue through the UKHSA Mosquito Watch scheme, as experts warn that warmer climates may increase future reports of invasive mosquitoes being able to survive in the UK.
