People infected with Zika virus can have flu-like symptoms including mild fever, skin rash, conjunctivitis, muscle and joint pain, malaise or headache which could last a few days to a week. Keep in mind that many people infected with Zika virus might not have the described symptoms or will only have mild symptoms. Therefore, many people might not realize they have been infected and are the carriers of the virus.
A diagnosis of Zika virus infection can only be confirmed through laboratory tests on blood or other body fluids, such as urine or saliva.
