Zika Virus

Zika is a virus that is spread through the bites of Aedes mosquitoes. It can also be spread through sexual contact, from a pregnant person to their baby and through blood transfusion, though that has not been reported in the U.S. Most people who get infected do not get sick. Those who do get sick usually experience mild symptoms, including fever, rash, joint pain and red eyes.

If a person is infected with Zika while pregnant, the child may be born with brain defects and a smaller head size (microcephaly). There is no vaccine or treatment for Zika, but acetaminophen and other medicines can help relieve symptoms.

Health care providers: Learn about laboratory test instructions and forms, health alerts and the latest guidance for Zika.

Zika in NYC

Zika has not been found in any types of mosquitoes in New York City. There were 987 cases of Zika in the city in 2016, with all of those linked to travel to a Zika-affected area. Since 2016, the number of cases has declined significantly.

While you cannot get Zika from local mosquitoes, they can spread other diseases, such as West Nile virus. Learn more about how you can help stop the spread of mosquito-borne viruses in and around your home.

Testing

You should only get tested for Zika if you meet the CDC's criteria. Your health care provider will determine if testing is appropriate for you and what type of test you should take. A test may result in a false positive, meaning it incorrectly shows you have Zika virus.

For help finding a provider who can test you for Zika, call 311.

Travel to a Zika-Affected Area

If you plan to travel to a Zika-affected area:

Learn about any warnings for pregnancy and sexual transmission.

Use insect repellent containing DEET, picaridin or oil of lemon eucalyptus.
