The UK Health Security Agency (UKHSA) says over 70 chikungunya cases were reported in the first half of 2025—more than double last year—linked to travel to India, Sri Lanka, and Mauritius. The virus causes fever and joint pain but cannot spread as mosquitoes that causes the spread are not present in UK, BBC reported.
UKHSA also confirmed the first UK cases of Oropouche virus, spread by midges, causing fever, headache, and muscle pain. Pregnant travellers are advised to take extra precautions.
