The symptoms of dengue resemble many other diseases including malaria, influenza, and Zika. [10] Blood tests are available to confirm the diagnosis including detecting viral RNA, or antibodies to the virus. [11] Treatment of dengue fever is symptomatic, as there is no specific treatment for dengue fever. In mild cases, treatment focuses on ...
These laboratory tests are only of diagnostic value during the acute phase of the illness with the exception of serology. Tests for dengue virus-specific antibodies, types IgG and IgM, can be useful in confirming a diagnosis in the later stages of the infection. Both IgG and IgM are produced after 5–7 days.
The mosquito-borne virus has a long history in warm climates but is now also emerging in regions where it had been generally unheard of—such as in Europe and parts of the U.S.
Dengue virus (DENV) is the cause of dengue fever.It is a mosquito-borne, single positive-stranded RNA virus of the family Flaviviridae; genus Flavivirus. [1] [2] Four serotypes of the virus have been found, and a reported fifth has yet to be confirmed, [3] [4] [5] all of which can cause the full spectrum of disease. [1]

About half of the world's population is at risk of mosquito-borne dengue disease with an estimated 100 million to 400 million infections occurring each year, according to the World Health ...
Dengue vaccine is a vaccine used to prevent dengue fever in humans. [9] Development of dengue vaccines began in the 1920s but was hindered by the need to create immunity against all four dengue serotypes. [10] As of 2023, there are two commercially available vaccines, sold under the brand names Dengvaxia and Qdenga. [11] [12]
NS1 antigen test (nonstructural protein 1) is a test for dengue, introduced in 2006. It allows rapid detection on the first day of fever, before antibodies appear some 5 or more days later. [1] It has been adopted for use in some 40 nations. The method of detection is through enzyme-linked immunosorbent assay.
