For the first time, invasive mosquito species capable of transmitting dengue and Zika viruses have been detected breeding in East London, according to a report released on September 8, 2026.
Public health officials have initiated a localized surveillance program to monitor the spread, noting that while the risk to the general public remains low, climate change is expanding the insects' habitat.
Residents are advised to eliminate standing water in gardens and use insect repellent, as the government prepares a vector control strategy to prevent the establishment of these populations in the UK.
