[10] It was the first illness shown to be transmissible by filtered human serum and transmitted by mosquitoes, by American doctor Walter Reed around 1900. [32]

[202] More than 100 of such viruses are now known to cause human diseases including encephalitis. [203] Yellow fever is the most notorious disease caused by a flavivirus ...
The genomes of these flaviviruses show close synteny with that of the flavivirus type species, yellow fever virus. [7] One flavivirus, the Wenzhou shark flavivirus , infects both Pacific spadenose sharks ( Scoliodon macrorhynchos ) and Gazami crabs ( Portunus trituberculatus ) with overlapping ranges, raising the possibility of a two-host ...
