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.
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 is generally found in mosquitoes and monkeys in a band of countries stretching across equatorial Africa) [10] and Asia (Malaysia, Philippines, Thailand, Vietnam, and Indonesia). [11] [12] [13] The first confirmed case of Zika fever in a human occurs in Uganda during 1964 in a field researcher, who experiences a mild, non-itchy rash. [4]
An epidemic of Zika fever, caused by Zika virus, began in Brazil and affected other countries in the Americas from April 2015 to November 2016. The World Health Organization (WHO) declared the end of the epidemic in November 2016, but noted that the virus still represents "a highly significant and long term problem". [2]
With 8,723 cases reported, it was the largest outbreak of Zika fever before the outbreak in the Americas that began in April 2015. [2] An earlier outbreak occurred on Yap Island in the Federated States of Micronesia in 2007, but it is thought that the 2013–2014 outbreak involved an independent introduction of the Zika virus from Southeast ...
The 2007 Yap Islands Zika virus outbreak represented the first time Zika virus had been detected outside Africa and Asia. It occurred in the Yap Islands, an island chain in the Federated States of Micronesia. Zika virus (ZIKV) is a vector-borne flavivirus in the same family as yellow fever, dengue, West Nile and Japanese encephalitis viruses ...
Mosquito-borne diseases that are sensitive to climate include malaria, lymphatic filariasis, Rift Valley fever, yellow fever, dengue fever, Zika virus, and chikungunya. [6] [7] [8] Scientists found in 2022 that rising temperatures are increasing the areas where dengue fever, malaria and other mosquito-carried diseases are able to spread.
Transmission of the virus into humans can lead to a viral infection known as Spondweni fever, with symptoms that include headache, nausea, myalgia (muscle pain) and arthralgia (joint pain). [ 1 ] [ 3 ] However, as SPONV is phylogenetically close to the ZIKV, it is commonly misdiagnosed as ZIKV along with other viral illnesses.
