Zika fever (also known as Zika virus disease) is an illness caused by Zika virus. [80] Around 80% of cases are estimated to be asymptomatic, though the accuracy of this figure is hindered by the wide variance in data quality, and figures from different outbreaks can vary significantly. [81]
Zika fever, also known as Zika virus disease or simply Zika, is an infectious disease caused by the Zika virus. [1] Most cases have no symptoms, but when present they are usually mild and can resemble dengue fever. [1] [4] Symptoms may include fever, red eyes, joint pain, headache, and a maculopapular rash.
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 ...
Viral pathogenesis is the study of the process and mechanisms by which viruses cause diseases in their target hosts, often at the cellular or molecular level. It is a specialized field of study in virology. [1] Pathogenesis is a qualitative description of the process by which an initial infection causes disease. [2]
However, in certain Spondweni virus cases, signs and symptoms can appear as early as three days after infection. [3] Six cases of Spondweni virus infections have been well documented, and the signs and symptoms parallel closely to Zika fever. [3] Symptoms included: fever; headache; nausea; myalgia; greyish mucoid lining on the posterior pharynx ...
Zika fever: The Zika virus is caused by the single stranded RNA Flavivirus that uses the Aedes mosquito as a vector to infect other human and animal hosts. [16] A 2015 zika virus strain isolated from a human in Brazil was used to infect pregnant rhesus macaques intravenously and intraamniotically. Both the dams and the placentas were infected ...

Uganda The Zika virus is first isolated in 1947 in a rhesus monkey in the Zika Forest near Entebbe, Uganda, and first recovered from an Aedes africanus mosquito in 1948. [4] [5] Serological evidence indicates additional human exposure and/or presence in some mosquito species between 1951 and 1981 in parts of Africa (Uganda and Tanzania having the first detection of antibody in humans, in 1952 ...
