 flavivirus is a genus of viruses in the family flaviviridae. this genus includes the west nile virus, dengue virus, tick-borne encephalitis virus, yellow fever virus, and several other viruses which may cause encephalitis. flaviviruses are named from the yellow fever virus, the type virus for the family; the word "flavus" means "yellow" in latin. the name "yellow fever" originated from its propensity to cause yellow jaundice in victims.the earliest mention of "yellow fever" appears in a manuscript of 1744 by dr. john mitchell of virginia; copies of the manuscript were sent to mr. cadwallader colden, a physician in new york, and to dr. benjamin rush of philadelphia; the manuscript was eventually reprinted in 1814. see: (dr. john mitchell) (written: 1744 ; reprinted: 1814) "account of the yellow fever which prevailed in virginia in the years 1737, 1741, and 1742, in a letter to the late cadwallader colden, esq. of new york, from the late john mitchell, m.d.f.r.s. of virginia," american medical and philosophical register â¦ , 4 : 181-215. the term "yellow fever" appears on p. 186. on p. 188, mitchell mentions "â¦ the distemper was what is generally called the yellow fever in america." however, on pages 191-192, he states "â¦ i shall consider the cause of the yellowness which is so remarkable in this distemper, as to have given it the name of the yellow fever." it should be noted, however, that dr. mitchell misdiagnosed the disease that he observed and treated, and that the disease was probably weil's disease or hepatitis. see: saul jarcho (1957) "john mitchell, benjamin rush, and yellow fever," bulletin of the history of medicine, 31 (2) : 132-6. flaviviruses share several common aspects: common size (40-65&nbsp;nm), symmetry ([[envelope (biology)|envelope
