Frequently asked questions
How is Zika virus transmitted?
Zika virus is primarily transmitted through the bite of an infected Aedes species mosquito. It can also be transmitted from a pregnant person to their fetus and through sexual contact.
What are the symptoms of Zika virus infection?
Many people infected with Zika virus do not develop symptoms. When symptoms do occur, they are usually mild and can include fever, rash, joint pain, conjunctivitis (red eyes), muscle pain, and headache. Symptoms typically last for up to a week.
Can Zika virus infection cause long-term health problems?
While most Zika infections are mild, the virus can cause serious birth defects in babies born to mothers infected during pregnancy, such as microcephaly. In rare cases, Zika infection in adults has been linked to Guillain-Barré syndrome.
How soon after potential exposure should I get tested?
Testing is most accurate when performed during the early stages of infection. Your healthcare provider will advise you on the best timing for testing based on your symptoms and potential exposure.
