The outbreak of yellow fever in Barcelona in 1821. The evolutionary origins of yellow fever are most likely African. [1] [2] Phylogenetic analyses indicate that the virus originated from East or Central Africa, with transmission between primates and humans, and spread from there to West Africa. [3]
The 1853 yellow fever epidemic of the Gulf of Mexico and Caribbean islands resulted in thousands of fatalities. Over 9,000 people died of yellow fever in New Orleans alone, [1] around eight percent of the total population. [2] Many of the dead in New Orleans were recent Irish immigrants living in difficult conditions and without any acquired ...
The family gets its name from the yellow fever virus; flavus is Latin for "yellow", and yellow fever in turn was named because of its propensity to cause jaundice in victims. [3] There are 89 species in the family divided among four genera. [2]
Flavivirus, renamed Orthoflavivirus in 2023, [3] is a genus of positive-strand RNA viruses in the family Flaviviridae.The genus includes the West Nile virus, dengue virus, tick-borne encephalitis virus, yellow fever virus, Zika virus and several other viruses which may cause encephalitis, [4] as well as insect-specific flaviviruses (ISFs) such as cell fusing agent virus (CFAV), Palm Creek ...
The first human virus to be identified was the yellow fever virus. [6] In 1881, Carlos Finlay (1833–1915), a Cuban physician, first conducted and published research that indicated that mosquitoes were carrying the cause of yellow fever, [7] a theory proved in 1900 by commission headed by Walter Reed (1851–1902).
Western Hemisphere populations were ravaged mostly by smallpox, but also typhus, measles, influenza, bubonic plague, cholera, malaria, tuberculosis, mumps, yellow fever, and pertussis. The lack of written records in many places and the destruction of many native societies by disease, war, and colonization make estimates uncertain.
There are more than 500 species of arboviruses, but in the 1930s only three were known to cause disease in humans: yellow fever virus, dengue virus and Pappataci fever virus. [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 ...
