UKHSA Warns of Resurgent Mosquito-Borne Diseases

The UK Health Security Agency (UKHSA) has reported a significant increase in mosquito-borne diseases, urging travellers to take precautions ahead of the Christmas holiday. In 2023, imported malaria cases reached 2,106, a 26% rise from 2022 and the highest level in nearly 25 years, with six related deaths. Dengue cases in returning travellers surged dramatically, with 473 cases reported in the first half of 2024 compared to just 157 in the same period last year, marking the highest incidence since monitoring began in 2009. Additionally, eight cases of the Zika virus were reported during the same timeframe. Health officials recommend measures such as using insect repellent and sleeping under treated nets to mitigate risks. The rise in these infections is attributed to increased travel post-pandemic and a resurgence of diseases globally, with the UKHSA emphasizing the importance of pre-travel health consultations.
