n. pl. fla·vi·vi·rus·es
Any of a genus of RNA viruses that are transmitted by insects and ticks, including the viruses that cause yellow fever, dengue, and various types of encephalitis.

[flav(o)- (because the virus causing yellow fever is the type species of the genus) + virus.]


1. (Medicine) a type of arbovirus that causes a wide range of diseases in humans, including yellow fever, dengue, and West Nile fever. It is spread by ticks or mosquitoes
2. (Microbiology) a type of arbovirus that causes a wide range of diseases in humans, including yellow fever, dengue, and West Nile fever. It is spread by ticks or mosquitoes
