Dengue fever, with a more severe form dengue hemorrhagic fever, is a tropical disease endemic in many countries. The name is pronounced 'DENG-ee' (IPA: /ˈdɛŋ gi/) or 'DENG-eh' (/ˈdɛŋ geɪ/).
- Etymological note: dengue is a word from the West Indies. It is derived from the Swahili name of the disease in Zanzibar, ka dinga pepo (ka partitive article, 'a, a kind of', dinga, dyenga, denga, 'sudden cramp-like seizure', pepo 'evil spirit, plague') (OED, 2020). This was "identified with Spanish dengue fastidiousness, prudery, with reference to the stiffness of the neck and shoulders caused by the disease)" (ibid).
