What is Zika Virus Disease (Zika)?
Zika is a disease caused by the Zika virus that is spread to people primarily through the bite of an infected Aedes species mosquito. The most common symptoms of Zika are fever, rash, joint pain, and conjunctivitis (red eyes). The illness is usually mild with symptoms lasting for several days to a week. People usually don’t get sick enough to go to the hospital, and they very rarely die of Zika.
The Aedes mosquitoes are aggressive daytime biters, and they can also bite at night. Infected mosquitoes spread the virus to other people through bites. It can also be transmitted from a pregnant mother to her fetus during pregnancy or around the time of birth.
Is this a new virus?
No. Outbreaks of Zika previously have been reported in tropical Africa, Southeast Asia, and the Pacific Islands. Zika Virus will likely continue to spread to new areas. In May 2015, the Pan American Health Organization issued an alert regarding the first confirmed Zika virus infection in Brazil. Since that time, local transmission has been reported in many other countries and territories.
