As winter holidays approach, UK travellers face a growing health concern. The UK Health Security Agency (UKHSA) has issued a warning about a sharp rise in mosquito-borne infections like malaria, dengue, and Zika virus.
New data reveals a significant increase in cases among returning travellers, urging Brits to adopt preventative measures before heading abroad.
A Surge in Infections: What You Need to Know
Recent reports indicate a worrying trend: mosquito-borne infections are rising globally and domestically. UKHSA data for 2023 shows 2,106 malaria cases, marking a 26% increase from the previous year and the highest figure since 2001. This spike is linked to increased international travel post-pandemic and a resurgence of malaria in several countries.
Dr Philip Veal, Consultant in Public Health at UKHSA, advises:
“Simple steps, such as using insect repellent, covering exposed skin, and taking malaria prevention tablets, can significantly reduce the risk of infection. Check the TravelHealthPro website for up-to-date health advice before travelling.”
Similarly, dengue cases have surged. Between January and June 2024, 473 dengue cases were reported in England, Wales, and Northern Ireland—a stark rise from 157 cases in 2023. This marks the highest number recorded in the first half of any year since 2009.
The Joint Committee on Vaccination and Immunisation (JCVI) now recommends a dengue vaccine for specific travellers.
Preventative Measures: Stay Safe on Your Travels
Taking the right precautions can significantly reduce the risk of contracting mosquito-borne diseases. The following steps are recommended by health officials:
- Use insect repellent: Opt for one containing DEET for maximum protection.
- Cover exposed skin: Lightweight, long-sleeved clothing offers a physical barrier.
- Sleep under insecticide-treated nets: Particularly useful in non-air-conditioned accommodations.
- Take malaria prevention tablets: When advised, ensure proper dosage adherence.

The Impact on Travellers
The surge in infections isn’t just a statistic—it’s a reminder that tropical diseases remain a serious threat. For instance, Zika virus, though rare, poses significant risks to pregnant women. Travellers visiting regions with known outbreaks must exercise caution.
Dr Dipti Patel, Director of the National Travel Health Network and Centre, urges people to plan ahead:
“Travellers should consult their GP or a travel clinic 4–6 weeks before departure to ensure vaccines and malaria prevention tablets are up to date. If you feel unwell after returning, seek immediate medical attention and inform your healthcare provider of your travel history.”
Final Thoughts: Be Prepared, Stay Protected
Whether you’re visiting tropical destinations or returning to familiar locations, don’t let mosquito-borne diseases catch you off guard.
