Britons are being advised to prioritize their safety while traveling abroad as recent data reveals over 1,000 cases of travel-related illnesses have been documented this year. Among the illnesses reported are malaria, dengue fever, and Zika virus.
Taking precautions such as receiving vaccinations, using malaria prophylaxis, and maintaining good hygiene practices can significantly reduce the risk of falling ill. The latest update from Travel Health Pro disseminated information from the UK Health Security Agency (UKHSA).
From January to June 2026 in England, Wales, and Northern Ireland (EWNI), several travel-related infections were reported. Zika virus, primarily transmitted by mosquitoes in regions like South and Central America, the Caribbean, Africa, and Asia, was responsible for eight cases. Indonesia was identified as the most common country of exposure, with four reported cases this year compared to only one case between 2014 and 2025.
Chikungunya, another mosquito-borne disease characterized by sudden fever and joint pain, accounted for 59 cases, with Sri Lanka being the predominant travel location. Malaria, a severe mosquito-borne infection, resulted in 557 reported cases in EWNI from January to May 2026.
Enteric fever, including typhoid and paratyphoid fever, caused 287 travel-associated cases. Dengue fever, transmitted by mosquitoes, led to 137 cases in England, with Southeast Asia and South Asia being the primary exposure regions, notably Thailand and the Maldives.
Dr. Hilary Kirkbride, a consultant epidemiologist and head of travel health at UKHSA, emphasized the importance of adequate preparation and planning for safe and enjoyable travel experiences. She recommended checking the TravelHealthPro website for destination-specific health advice, required vaccinations, and essential medications like antimalarials. Protective measures against mosquito-borne illnesses, such as using insect repellent and ensuring proper food and water hygiene, were also highlighted.
Travelers, especially pregnant individuals or those trying to conceive, were urged to seek advice from healthcare professionals before embarking on trips. Even repeat visitors to specific countries were advised to take necessary precautions, as natural immunity may not offer sufficient protection against infections. For ongoing health advice during travel, visitors were directed to the Travel Health Pro website.
