Flavivirus

 
a genus of flaviviruses of worldwide distribution, containing about 75 species in 9 serogroups. It includes the viruses that cause yellow fever, dengue, Japanese B encephalitis, Kyasanur Forest disease, St. Louis encephalitis, tick-borne encephalitis, and West Nile encephalitis. Mosquitoes are the most common vector, with some species being tick-borne and some having no known vector.

Flavivirus

/Fla·vi·vi·rus/ (fla´vĭ-vi″rus) group B arboviruses: a genus of viruses of the family Flaviviridae, many members of which cause disease in humans and animals, including the agents of yellow fever, dengue, and St. Louis and other forms of encephalitis.

Flavivirus

a genus of a family of Flaviviridae single-stranded positive-sense ribonucleic acid viruses, including species that cause yellow fever, dengue, and St. Louis encephalitis. Most are arboviruses transmitted by mosquitoes or ticks. Also called group B arbovirus.

flavivirus

A member of the flavivirus genus of the Flaviviridae family. Flaviviruses are arthropod-borne (arbor) viruses and can cause encephalitic or meningitic diseases including Japanese encephalitis, West Nile virus encephalitis, St. Louis encephalitis and Murray Valley encephalitis.

Although the testing method used for the studies in Nigeria and Cameroon studies would minimize overestimation of DENV infection prevalence because of cross-reactive antibodies to other flavivirus infections or yellow fever vaccination, use of an immunoglobulin G ELISA in the Burkina Faso study did not differentiate these infections.
Monath (31) and Gubler (2) hypothesized that immunologic cross-protection from heterotypic antibodies to other flavivirus infections (DENV and Japanese encephalitis virus) could explain the absence of yellow fever virus in Asia.
Although deficiency of the receptor protects against acquisition of HIV, evidence is accumulating to suggest it plays a role in severity of illness caused by flavivirus infections (7,8).
90] results showed that among secondary flavivirus/ZIKV-probable patients, the neutralizing antibody response was higher to ZIKV and more cross-reactive, a finding commonly observed among secondary flavivirus infections.
Serologic testing by immunoglobulin (Ig) M-capture ELISA with DENV antigen confirmed recent flavivirus infection in several patients.
Historically, flavivirus infections have been diagnosed by serologic tests or vials isolation (15).
A rapid diagnostic system was developed to detect and differentiate various flavivirus infections on the basis of the results of 1-step real-time polymerase chain reaction (PER) and envelope membrane (E/M)-specific capture immunoglobulin (Ig) M and IgG enzyme-linked immunosorbent assay (ELISA) (5-7).

However, secondary flavivirus infections are notorious for heterologous reactivity, so infection by WNV or other flaviviruses causing these reactions could not be ruled out.
Although persons with CVID are at increased risk for enteroviral meningoencephalitis, a greater susceptibility to arthropodborne flavivirus infections has not been reported.
PRNTs on the Jamaican bird samples indicated 18 WNV infections, 3 SLEV infections, 5 undetermined flavivirus infections (positive results for two or more viruses without a fourfold difference in antibody titer); one additional reactive serum sample was negative for the three viruses tested.
