TLDR
The data suggest that it is possible to use a single dilution as a cutoff point to predict with reasonable accuracy, if a patient has had a recent dengue infection.Abstract:
A dot enzyme immunoassay (DEIA) was used to determine the levels of antibody to dengue 3 virus in the acute and convalescent sera of febrile patients with a clinical diagnosis of dengue fever or dengue haemorrhagic fever. The antibody titres were compared with titres determined by the haemagglutination inhibition (HI) test. The results of the study showed that, besides being more simple to perform, the DEIA is in order of magnitude more sensitive than the HI test. Furthermore, the data suggest that it is possible to use a single dilution as a cutoff point to predict with reasonable accuracy, if a patient has had a recent dengue infection. The DEIA test for antibodies to dengue virus is an appropriate technology highly suitable for rapid diagnosis and surveillance in developing countries.read more

TL;DR: Results indicated that the ICT evaluated in the selected studies can both rule in and rule out disease but is more accurate when samples are collected later in the acute phase of infection.

TL;DR: There is no specific treatment for dengue; hydration is important as well as aggressive fluid management if hypotension develops, and it is important to avoid aspirin and salicylates.

TL;DR: A small subset of patients with DHF will develop features of circulatory collapse, the DSS – dengue shock syndrome which has a high case fatality rate and is now increasingly diagnosed in the Indian subcontinent.
