In humans, it initially causes a mild illness known as Zika fever, Zika, or Zika disease, which since the 1950s has been known to occur within a narrow equatorial belt from Africa to Asia.
In 2014, the virus spread eastward across the Pacific Ocean to French Polynesia, then to Easter Island and in 2015 to Central America, the Caribbean, and South America, where the Zika outbreak has reached pandemic levels.Zika virus is related to dengue, yellow fever, Japanese encephalitis, and West Nile viruses.

In January 2016, the U.S. Centers for Disease Control and Prevention (CDC) issued travel guidance on affected countries, including the use of enhanced precautions, and guidelines for pregnant women including considering postponing travel.
Other governments or health agencies soon issued similar travel warnings,while Colombia, the Dominican Republic, Ecuador, El Salvador,and Jamaica advised women to postpone getting pregnant until more is known about the risks.
