Abstract

Somaliland experienced a large dengue fever outbreak between 2023 and 2024. National laboratory surveillance identified 4971 clinically suspected cases that underwent testing (‘tested probable cases’), of which 1703 were confirmed using rapid diagnostic tests. Three deaths were reported. Cases spanned five regions of Somaliland, with 74% in Marodijeh. As surveillance data were restricted to public-sector facilities, these findings represent a lower-bound estimate of true dengue transmission. Contribution: We highlight the utility of the new laboratory surveillance and the need for mitigating dengue risks amid climatic fluctuations.
