Zika is a virus spread to humans by Aedes mosquitoes. It usually causes mild illness, with most people sick with the virus getting a slight fever and skin rash. Only one in five people who get the virus experience symptoms, and the symptoms usually last from three to 14 days. The best protection from Zika virus is preventing mosquito bites. The World Health Organization has declared the continuing spread of Zika virus disease in Latin America and the Caribbean a “Public Health Emergency” in reaction to a link between the virus and birth defects and neurological disorders.
