Zika Virus

What is the Zika Virus?

The Zika virus is a Flavivirus related to dengue fever, West Nile virus, yellow fever, and Japanese encephalitis viruses. Zika fever, as it is also known, is transmitted to humans through bites from a mosquito infected with the Zika virus.

Common Zika infection symptoms include rash, fever, and joint pain as well as inflammation of the conjunctiva of the eyes, leading to redness. Typically, the illness is mild and lasts from a few days to a week.

 

Serious illness is rare, but in February 2016, the World Health Organization declared Zika virus infections as a public-health emergency due to severe birth defects associated with Zika infections during pregnancy.

Where Did The Zika Virus Come From?

The Origin of Zika Virus

The Zika virus origin is in the Zika Forest of Uganda. In 1947, the Zika virus was isolated and identified in Uganda. Blood tests from patients in 1951-1981 concluded that the Zika virus had spread to other African countries and even Indonesia.

Zika Outside of Africa and Indonesia

In 2007, Zika virus was found on Yap Island in the Indo-Pacific, which was the first documented account of the virus outside of Africa or Indonesia. Zika virus has continued to spread to North and South America.
