The disease is caused by the yellow fever virus and is spread by the bite of an infected mosquito. [3] [8] It infects humans, other primates, [9] and several types of mosquitoes. [3] In cities, it is spread primarily by Aedes aegypti, a type of mosquito found throughout the tropics and subtropics. [3] The virus is an RNA virus of the genus ...
Aedes aegypti (UK: / ˈ iː d iː z /; US: / eɪ d z / or / ˈ eɪ d iː z / from Greek αηδής 'hateful' and / eɪ ˈ dʒ ɪ p t i / from Latin, meaning 'of Egypt'), the yellow fever mosquito, is a mosquito that can spread dengue fever, chikungunya, Zika fever, Mayaro and yellow fever viruses, and other disease agents.
The Flaviviridae are part of RNA virus supergroup II, which includes certain plant viruses and bacterial viruses. [2] The family has four genera: [1] [2] Genus Flavivirus, renamed Orthoflavivirus in 2023, (includes Dengue virus, Japanese encephalitis, Kyasanur Forest disease, Powassan virus, West Nile virus, Yellow fever virus, and Zika virus)
(The CDC has yellow fever maps that can help pinpoint the specifics, too.) “The yellow fever vaccine is safe and offers lifelong immunity against the disease,” Park says. “Currently, the ...
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 ...
Yellow fever is a relative of the dengue and Zika viruses but is far deadlier. Most people don't even know they are infected, but 15 percent can develop serious illness and as many as 60 percent ...
The initial yellow fever vaccination provides lifelong protection for most people and provides immunity within 30 days of the vaccine. Reactions to the yellow fever vaccine have included mild headache and fever, and muscle aches. There are rare cases of individuals presenting with symptoms that mirror the disease itself.
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]
