Learn about Zika Virus as of 6/20/2016

Basic Facts

  • People usually get Zika through a mosquito bite—but only certain kinds of mosquitoes (Aedes mosquitoes) can spread Zika.
  • Zika can also be spread through sexual contact and blood contact (i.e. blood transfusions, sharing injection equipment, etc.). Zika is not spread by casual contact.
  • Most people (80%) who get infected with Zika do not get sick. For those who do get sick, the sickness is usually mild.
  • Since Zika causes birth defects, there is special guidance related to pregnancy. See below.
  • There is no Zika vaccine and no medicine that treats Zika.


Most people with Zika (80%) have no symptoms and may not know they are infected.
For those who have symptoms, the most common symptoms are fever, rash, joint pain and conjunctivitis (red eyes). Most people have mild symptoms and do not need to go to a hospital. Severe complications, such as paralysis or brain infection, are rare. Symptoms usually start two to 12 days after being bitten by an infected mosquito and may last up to a week.
Zika symptoms are similar to symptoms of other diseases caused by mosquitoes, such as dengue virus or chikungunya virus.


Zika testing may include urine or blood tests. Most people do not need to get tested for Zika virus, even if they traveled to a place where Zika is spreading. Testing is most important for pregnant women who spent time in a Zika-affected area or who, while pregnant, had condomless sex with a man who spent time in a Zika-affected area.


There is no treatment for Zika, but medicine (like acetaminophen) can help relieve the symptoms. Most people recover on their own by resting and drinking fluids.

Affected Areas

Zika is affecting parts of Central and South America, Mexico, the Caribbean and other places listed by the Centers for Disease Control and Prevention. (Find the latest Zika-affected locations at cdc.gov/zika.) The type of mosquito linked to the current outbreak, Aedes aegypti, lives in these places. Aedes aegypti has not been found in New York City.

A different Aedes mosquito is found in New York City. This mosquito is called Aedes albopictus. Aedes albopictus is able to spread Zika to people, but health experts are still learning whether it is likely to spread Zika to people. Just because a mosquito can carry the virus does not mean that it will cause an outbreak. Health experts have not found Zika in any local mosquitoes but are planning for the possibility that Aedes albopictus could get infected with Zika locally and are taking aggressive steps to monitor this and take action if needed. Read “What the City is Doing” on nyc.gov/health/zika for the City’s latest actions.

Pregnancy Warning

Zika is not dangerous for most people. However, Zika causes birth defects. One birth defect linked to Zika is a smaller than normal head. This condition is called “microcephaly.” Health experts are still learning about the link between Zika and microcephaly. The latest guidance to avoid this risk is below.

Guidance for Pregnant Women and Their Male Sex Partners

Pregnant woman who did not travel to a Zika-affected area Postpone travel until health experts say it’s safe.

If it’s not possible to delay travel, talk to a health care provider first, and take steps to protect yourself while traveling. Review the guidance below on sexual transmission and safe and healthy travel.

Pregnant woman who did travel to a Zika-affected area Call your health care provider to discuss Zika testing.
Pregnant woman’s male sex partner traveled to a Zika-affected area

Plan together to abstain from sexual activity or use condoms correctly every time you have vaginal, anal and/or oral sex for the duration of the pregnancy.

If you’re pregnant and had condomless vaginal, anal or oral sex with a man who spent time in a Zika-affected area, contact your health care provider to discuss Zika testing.

If you’re pregnant and had condomless vaginal, anal or oral sex with a man who spent time in a Zika-affected area, contact your health care provider to discuss Zika testing.

Guidance for People Trying to Conceive

Woman has or might have Zika* Symptoms Wait at least eight weeks after symptoms started before trying to conceive
No symptoms Wait at least eight weeks after last possible Zika exposure before trying to conceive
Man has or might have Zika* Symptoms  Wait at least six months after symptoms started before trying to conceive
No symptoms Wait at least eight weeks after last possible Zika exposure before trying to conceive

*This includes people who traveled to a Zika-affected area or had condomless vaginal, anal or oral sex with a man who spent time in a Zika-affected area.

Find more information about Zika and pregnancy at nyc.gov/health/zika and cdc.gov/zika/pregnancy.

Sexual Transmission

Zika can spread from one person to another through sexual contact. Health experts are still learning about this risk but recommend that people who travel to Zika-affected areas use condoms and birth control while they are traveling and after they return home. Condoms may stop Zika from spreading sexually. Birth control helps prevent pregnancy in which one or both sex partners might have Zika.

Guidance for non-Pregnant people

While traveling to a Zika-affected area Use birth control and condoms correctly
After returning home from a Zika-affected area Women should continue using birth control to prevent pregnancy for eight weeks after returning home.
Man has symptoms or positive Zika test Use condoms correctly every time you have vaginal, anal and/or oral sex for six months after returning home
Man has no symptoms and no positive Zika test Use condoms correctly every time you have vaginal, anal and/or oral sex for eight weeks after returning home.

For a complete list of birth control options, visit nyc.gov and search “birth control”.

Blood Donation

It is rare but possible for Zika to spread from one person to another through a blood transfusion. To help prevent this from happening, follow the guidance below:

Guidance for Donating Blood

People who traveled to an affected area Wait four weeks after returning home before donating blood.
People who had sex (vaginal, anal or oral) with a man who was in an affected area within three months of the latest sexual contact Wait four weeks after the last sexual contact before donating blood.
People who traveled to an affected area and already donated blood within four weeks of returning home

Tell the facility where you gave blood if you have two or more of these symptoms within two weeks of giving blood: fever, joint pain, rash or conjunctivitis (red eyes).

If you have symptoms, avoid donating more blood until the symptoms have been gone for at least four weeks.

Infants and Children

According to the CDC:
  • Infants and children can get Zika.
  • Symptoms in infants and children are the same as those described above in “Symptoms.”
  • Infection with Zika around the time of birth or in early childhood has not been linked to microcephaly.
  • Zika has been found in breastmilk, but there are no reports of mothers spreading Zika to their infants through breastmilk. The CDC encourages mothers in Zika-affected areas to keep breastfeeding because of its many benefits.
  • More information for parents is available at cdc.gov/zika.

Safe and Healthy Travel

If you are traveling to a Zika-affected area, read the pregnancy and sexual transmission warnings above, and take steps to avoid mosquitoes. The tips below are important for everyone traveling to a Zika-affected area—but especially for pregnant women who cannot delay travel.
The type of mosquito linked to the current outbreak is very aggressive. The mosquito bites during the day and early evening.

  • Use insect repellent containing DEET, picaridin or oil of lemon eucalyptus (not for children under 3 years old).
    • Use repellents approved by the EPA, and follow the directions on the label
    • Apply sunscreen first, then repellent.
    • Insect repellent is safe for pregnant women.
    • Do not use insect repellent on infants less than 2 months old. Do not allow young children to apply insect repellent themselves.
    • Do not apply insect repellent to a child’s hands, eyes, mouth or any irritated skin or cuts.
  • Wear long sleeves and pants; dress children the same way. Wear clothing treated with permethrin (a chemical that repels insects).
  • Stay in places with air conditioning or window and door screens.
  • Use a mosquito bed-net if you cannot keep mosquitos out of your residence. Cover cribs, strollers and baby carries with mosquito netting.
  • Get rid of standing water that collects in and around your residence, because standing water attracts mosquitoes.

The CDC recommends that travelers returning to the U.S. from Zika-affected places take steps to prevent mosquito bites for three weeks, even if they do not feel sick, to avoid spreading Zika to local mosquitoes.

Mosquito Prevention in New York City

Zika has not been found in New York City mosquitoes, but local mosquitoes can spread other diseases, like West Nile virus. New Yorkers can help stop the spread of mosquito-borne viruses by following these steps: 

  • Apply insect repellents and wear long sleeves or pants in the evening during peak mosquito season (June through September).
  • Install or repair screens on windows and doors.
  • Empty standing water from containers such as flower pots, gutters, buckets, pool covers, pet water dishes, discarded tires and birdbaths. A very small body of water can be the breeding ground for hundreds of mosquito eggs.
  • Make sure backyard pools are properly maintained and chlorinated.
  • Report standing water to 311. The Health Department inspects standing water complaints and files notices of violation against property owners who fail to get rid of it. When standing water cannot be drained, the City applies treatments called larvicides that kill mosquitoes before they mature and can spread disease.
