Dengue vector mosquito larvae found in UK homes for first time

Aedes aegypti larvae were detected in residential properties in London, marking the first confirmed reproduction of the dengue, zika, and yellow fever vector in the UK. The public health risk is assessed as very low, but the establishment of a competent vector in a temperate climate signals a northward shift in disease transmission potential. Uncertainty remains over the extent of the population and whether it can overwinter.
