Aedes -borne febrile exanthems in UK dermatology: lessons from European transmission

The first documented breeding of Aedes aegypti in the United Kingdom creates a new diagnostic context for dermatologists. European transmission data show that locally acquired arboviral disease may circulate for weeks before recognition and that early recognised cases can present with febrile eruptions. This letter translates those lessons and WHO evidence into a practical framework for distinguishing dengue chikungunya and Zika and for deciding when arboviral testing should extend beyond travel history.
