Zika fever (also known as Zika virus disease) is an illness caused by Zika virus. [79] 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. [ 80 ]
Medical importance. Adult Aedes apicoargenteus are human-biters, and vectors of Zika virus, the causative agent of Zika fever. [5] References This ...
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 .
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.
Arthropods are common vectors of disease.A vector is an organism which spreads disease-causing parasites or pathogens from one host to another. Invertebrates spread bacterial, viral and protozoan pathogens by two main mechanisms.
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 ...
Diseases that are not usually transmitted directly by blood contact, but rather by insect or other vector, are more usefully classified as vector-borne disease, even though the causative agent can be found in blood. Vector-borne diseases include West Nile virus, zika fever and malaria.
A disease is often known to be contagious before medical science discovers its causative agent. Koch's postulates, which were published at the end of the 19th century, were the standard for the next 100 years or more, especially with diseases caused by bacteria. Microbial pathogenesis attempts to account for diseases caused by a virus.
