Quick Summary

Invasive Aedes aegypti mosquitoes, which can carry deadly viruses such as dengue, chikungunya, and Zika, have been found breeding in east London for the first time. According to Dr Jolyon Medlock of UKHSA, the risk to the public is assessed as very low, but residents are being advised to remove standing water from their gardens to prevent further breeding. The mosquitoes are believed to be accidental importations and cannot survive long-term in the UK climate. This is the fourth time Aedes aegypti has been detected in the UK in recent years.

Story summary

Aedes aegypti, a mosquito species that can carry deadly viruses such as dengue, chikungunya, and Zika, has been found breeding in homes in east London. This is the first time this invasive species has been identified breeding in the UK. According to Dr. Jolyon Medlock of the UKHSA, the risk to the public is considered very low because there is no evidence that these mosquitoes have caused human infections or been detected in nearby areas. Control measures have already been taken to destroy the larvae and the area is being closely monitored to prevent further breeding. Experts believe that the mosquitoes were accidentally imported to the UK through vehicles, baggage, or imported plants, which can carry them if they find a suitable climate. The presence of these mosquitoes is not linked to any recent heatwaves in the area.
