Tools for studying Dengue Virus

 

Dengue virus
Dengue fever is caused by infection of dengue virus and transmitted by mosquitoes. Dengue virus (DENV) is a single-stranded RNA virus belonging to family Flaviviridae. There are 4 serotypes of the virus (called DEN-1, -2, -3 and -4) have been found. The DENV genome encodes 3 structural (capsid C, membrane M, and envelope E) and 7 nonstructural (NS1, NS2A, NS2B, NS3, NS4A, NS4B, and NS5) proteins.

Dengue diagnostic testing
Laboratory diagnosis of dengue can be made by detecting viral RNA, NS1 protein, IgM and IgG against DENV. NS1 protein, the early diagnosis marker, can be detected in DENV-infected patients as early as 1 day post onset of symptoms. For primary infection (first dengue or other flavivirus infection), IgM levels are useful for diagnosis of infection by day 3-5 up to over 2–3 months after onset, and IgG levels are elevated after 10-14 days and remain detectable for life. During secondary infection (had dengue or other flavivirus infection in past), IgG levels rise rapidly from 1-2 days after the onset of symptoms. IgM/IgG antibody ratios are commonly used to distinguish primary and secondary infection: primary infection patients have a higher IgM/IgG ratio while IgG levels are typically higher in the secondary infection stage.
