The Full Story

A plain summary built from the channels that reported this story.

Experts have confirmed that a disease-carrying mosquito species has bred in the UK for the first time. The Aedes aegypti mosquito, which can transmit yellow fever, dengue and Zika, was found in residential properties in East London. Scientists say the warming climate is making such invasions more likely, but they assess the risk to public health as low.

The species is native to Egypt and North Africa and has been spreading through Europe. This is the fourth time it has been spotted in the UK, but the first time it is known to have bred. The mosquitoes can pass on diseases that can be deadly to humans. However, experts say the presence of a single mosquito is not a reason for alarm, as they can hitchhike in luggage from tropical countries. They are monitoring the situation closely.

The long-term prospect of the species overwintering in the UK is very low because temperatures are not high enough. Until the autumn chill, the advice is to remove standing water from gardens and avoid being bitten.
