In 2024, the UK experienced a significant increase in imported dengue fever cases, with 904 reported instances among returning travellers in England, Wales, and Northern Ireland. This marks the highest number since surveillance began in 2009 and represents a 43% rise from the 631 cases reported in 2023. All cases were linked to travel abroad, predominantly to Southern and South-Eastern Asia.
Understanding Dengue Transmission
Dengue fever is transmitted primarily by the Aedes aegypti mosquito, which thrives in tropical and subtropical regions. The virus spreads when a mosquito bites an infected person and subsequently bites another individual, transmitting the virus . Factors such as climate change, increased travel, and urbanisation have contributed to the expanding range of these mosquitoes, raising concerns about the global spread of dengue.
Preventing Mosquito Bites: A Crucial Step
With no specific antiviral treatment for dengue, prevention remains the most effective strategy. The UK Health Security Agency (UKHSA) advises travellers to use insect repellents, wear protective clothing, and sleep under insecticide-treated bed nets to minimise the risk of mosquito bites.
