Aedes aegypti mosquitoes found breeding in East London

The UK Health Security Agency (UKHSA) has launched a programme to eradicate Aedes aegypti mosquitoes after discovering them breeding at residential properties in East London. This marks the first time the species has been identified as actively breeding in the United Kingdom, although the insects have been detected in the country previously.

Authorities believe the mosquitoes may have arrived in the UK via imported plants, baggage, or vehicles from tropical regions. While Aedes aegypti can transmit diseases such as dengue, Zika, and chikungunya, the UKHSA states the immediate public health risk remains very low. There is currently no evidence of human infection or that larvae have spread to public areas.

Experts note that while the species typically cannot survive long-term in the UK climate, rising global temperatures and increased movement of goods and people may lead to more frequent incursions. Dr. Jolyon Medlock of the UKHSA advised the public to help reduce breeding sites by removing standing water from gardens and outdoor containers.
