UK reports surge in chikungunya cases among travelers, sees first Oropouche virus cases.

UK health officials warn of increased chikungunya cases among travelers returning from abroad, with 73 cases reported this year, up from 27 last year. The virus, spread by mosquito bites, causes fever and joint pain. The UK has also detected its first cases of the Oropouche virus, linked to travel from Brazil. While no risk of local transmission exists, officials urge travelers to use insect repellent, cover skin, and use bed nets to prevent bites.
