Dengue and malaria cases rise as British tourists return from popular destinations, prompting urgent travel and health advisories.

The UK Health Security Agency reports a significant uptick in mosquito-borne diseases among British holidaymakers. Returning travellers from global hotspots face health risks from infections such as dengue and malaria, requiring increased caution and preventive measures.

Authorities urge holidaymakers to adopt safety protocols due to the escalating number of diseases noted in individuals returning from some of the most visited regions worldwide. Data indicate many travellers have contracted illnesses like dengue and malaria, known for their transmission through mosquito bites. These conditions can result in severe health issues, and experts emphasize the necessity for tourists to implement protective measures to minimize health threats while abroad.

Confirmed cases of these diseases have spread across the UK, affecting people who had recently travelled internationally. In 2023, England, Wales, and Northern Ireland reported 634 cases of dengue among returning travellers, a number that closely mirrors figures from the pre-pandemic year of 2019, which saw 790 cases. Most dengue cases in 2023 originated from South and Southeast Asia, particularly India, with a noted rise in cases from Central America and the Caribbean due to recent outbreaks there.

The World Health Organization (WHO) highlighted a global increase in dengue cases in 2023, with over five million instances and 5,000 deaths. England confirmed a total of 1,637 malaria cases from January to October 2023. Malaria cases also returned to pre-pandemic levels, akin to the 1,719 cases reported in the UK in 2019, aligning with the decade’s average.

Moreover, the WHO reported an estimated 249 million malaria cases globally in 2022, an increase from pre-pandemic figures. Zika virus remains a lesser but persistent threat, with eight cases recorded in England in 2023, which is consistent with the previous year. The peak of Zika cases was in 2016 during the outbreak in America.

Dr Philip Veal, a Consultant in Public Health at the UK Health Security Agency, stated, “With the increase in travel following the pandemic’s travel restrictions lift, serious mosquito-borne infections have surged. Simple preventative measures like using insect repellent, covering exposed skin, and sleeping under treated bed nets can significantly reduce the risk of infections such as malaria, dengue, and Zika.”

Dr. Dipti Patel, Director of the National Travel Health Network and Centre advises travelers to prioritize their health by planning. “Consult the TravelHealthPro website for the latest health information and advice on your destination. Speak to your GP or a travel health clinic well before your trip to ensure you receive all necessary vaccinations and advice for a safe and healthy journey.”
