   Jun 13, 2019 · As the immune system fights the infection, IgM antibodies against dengue virus are detectable starting 4-5 days after onset of symptoms and are reliably detectable for approximately 12 weeks. Combined testing with a nucleic acid amplification test (NAAT) and MAC-ELISA usually provides a diagnostic result during the first 1-7 days of illness.

   Laboratory diagnosis methods for confirming dengue virus infection may involve detection of the virus, viral nucleic acid, antigens or antibodies, or a combination of these techniques. After the onset of illness, the virus can be detected in serum, plasma, circulating blood cells and other tissues for 4–5 days.

   Which proteins are involved in the pathogenesis of dengue virus?

   • Dengue virus genome encodes for three structural proteins (C, prM (M), and E) and seven non-structural (NS) proteins (NS1, NS2a, NS2B, NS3, NS4a, NS4B, and NS5). The most important non-structural protein which has been implicated in the pathogenesis of dengue viral infections is NS1 [ 23 ].

   How is dengue virus detected?

   • During this period, dengue virus is typically present in blood or blood-derived fluids such as serum or plasma. Dengue virus RNA can be detected with molecular tests. The non-structural protein NS1 is a dengue virus protein that also can be detected using some commercial tests. A negative result from a molecular or NS1 test is not conclusive.

   How is a dengue virus structured?

   • Fig. 2. Genomic structure of dengue virus (created in Biorender). This dengue is structured in an icosahedral shape and has an envelope formed by a layer of protein at its outer core. The icosahedral core is forty to fifty nanometers in diameter and has a C-protein viral genome.
