Question to the Department of Health and Social Care:
To ask His Majesty's Government what data they hold on the (1) incidence, and (2) impact, of dengue fever on different demographic groups in the UK.
Dengue case numbers in the United Kingdom were provided annually to the European Centre for Disease Prevention and Control until 2019, which is the most recent data available. This information showed there were 827 dengue cases in the UK in 2019.
The UK Health Security Agency (UKHSA) holds data on dengue infections in England, Wales and Northern Ireland, comprised of laboratory reports from the UKHSA’s Rare and Imported Pathogens Laboratory at Porton Down. However, the UKHSA does not routinely receive information on outcomes and clinical details, including information on symptoms, deaths and risk groups for these cases. In the event of an apparent increase in dengue cases, the UKHSA would undertake additional investigations.
