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 ]
A Zika virus infection might be suspected if symptoms are present and an individual has traveled to an area with known Zika virus transmission. [29] Zika virus can only be confirmed by a laboratory test of body fluids, such as urine or saliva, or by blood test.
It is estimated that 1.5 million people were infected by Zika virus in Brazil, [3] with over 3,500 cases of infant microcephaly reported between October 2015 and January 2016. [4] The epidemic also affected other parts of South and North America, as well as several islands in the Pacific. [5] Zika virus spread to Brazil from Oceania in 2013 or ...

Pregnant women infected with Zika virus are at a higher risk of giving birth to children with congenital malformations, including microcephaly. [81] In the context of climate change and temperature rise, it is predicted that Zika virus will affect more than 1.3 billion people by 2050. [82]
In 2000–2002, the 1990 study was updated by WHO to include a more extensive analysis using a framework known as comparative risk factor assessment. [ 5 ] The WHO estimates were again updated for 2004 in The global burden of disease: 2004 update (published in 2008) [ 7 ] and in Global health risks (published in 2009).
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 ...
