Zika virus is primarily spread to people through mosquito bites. Once the virus is in a person, it can spread through blood transfusion, sexual contact, and from mother to child. Those at the highest risk of contracting Zika virus are people who travel to areas where Zika virus is being actively transmitted and those who have had sex with someone who has been infected with Zika virus or has traveled to an area with Zika. Local transmission has been reported in the continental United States, but has not been reported in Utah.

The most common symptoms of Zika virus disease are fever, rash, joint pain, and conjunctivitis (red eyes). About 80% of people with Zika experience no symptoms and don’t even know that they have the virus. The illness is usually mild with symptoms lasting from several days to a week. People usually don’t get sick enough to go to the hospital, and they very rarely die of Zika.
