Deadly Mosquitoes Still Breeding in London
23 Sep
Summary
- Tropical mosquitoes capable of spreading dengue and Zika are breeding in London.
- Disease-carrying insects persist despite UKHSA efforts to eradicate them.
- Officials urge public to remove standing water to curb mosquito spread.

Weeks after their first detection in the UK, invasive Aedes aegypti mosquitoes, known carriers of dengue fever and Zika viruses, are still breeding in east London. Small colonies of these tropical insects are being detected in residential areas, prompting continued eradication and surveillance efforts by the UK Health Security Agency (UKHSA).
Dr. Jolyon Medlock of UKHSA stated that measures like removing suitable habitats, treating drains, and community engagement are ongoing. While the exact pathway of their introduction to the UK remains unclear, possibilities include being brought back in luggage or hidden on tropical plants. The UKHSA advises the public to eliminate standing water in gardens to reduce breeding grounds.
