Dengue is an endemic viral disease affecting human health particularly children. Students are expected to know the main diagnostic test(s) of the particular infection. However, dengue vaccine development has been complicated due to the unique and complex immunopathology of dengue. We found that 4 out of 5 negative samples had high viremia (Ct below 30), which means that it may be too early to produce sufficient IgM. Epitope analysis of recombinant DENV envelope domain III. Five qRT-PCR negative dengue samples were wrongly detected as positive in at least one of the four whole-dengue serotype virus ELISA (see Figure S4 ). But for some, particularly children, the virus can develop into the far more serious dengue hemorrhagic fever, causing severe blood loss and even death. Conflicts of Interest The authors declare no conflict of interest. There is an urgent need to develop a safe and effective vaccine that induces protective immune response to all the four serotypes overcoming antibody dependent enhancement.

Dengue virus is a member of the Flavivirus genus and consists of four serotypes (DV-1, DV-2, DV-3, and DV-4), each of which is capable of causing dengue fever and the more severe dengue hemorrhagic fever or dengue shock syndrome. Augmented Personalized Health: an explicit knowledge enhanced neurosymbolic d. When this happens, macrophages and monocytes clear the virus from the bloodstream by binding to and engulfing the antibody-coated viruses which can no longer escape the endocytic vacuole and destroying them (4).
