The first human virus to be identified was the yellow fever virus. 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, a theory proved in 1900 by commission headed by Walter Reed (1851–1902).
Feb 27, 2022 · Yellow fever (YF) is a mosquito-borne viral illness caused by an arbovirus of the family Flaviviridae, genus Flavivirus, encompassing positive-single-stranded RNA viruses. The virus was isolated for the first time in 1927 in a male patient [ 1 ]. Transmission is primarily by mosquitoes [ 2 ].

Nov 11, 2016 · A Brief History of Virology. The history of virology can be divided into a number of eras: these span (1) the discovery of viruses as entities distinct from other disease-causing pathogens, (2) the association of many major human diseases with causative viruses, (3) the development of methods for virus isolation and characterization, (4) the ...

Oct 17, 2019 · Yellow fever was historically the first described viral hemorrhagic fever (VHF) and its causative agent, the yellow fever virus (YFV), is the prototypic member of the family Flaviviridae. Pioneering experimental work in the 19th century identified the Aedes aegypti mosquitos as the vector responsible for transmission to humans, facilitating ...

Nov 8, 2023 · Yellow fever. Yellow fever is a viral disease that is transmitted to humans by the bites of infected mosquitoes. It is prone to epidemics and is preventable with a vaccine. These day-biting mosquitoes breed around houses (domestic), in forests or jungles (wild), or in both habitats (semi-domestic). Yellow fever is a high-impact, high-threat ...
