Zika is a flavivirus, which is pronounced a bit a like flavor. Flay-v-virus. Most viruses in this family are carried by arthropods — mosquitoes and ticks. We’ve known about Zika virus since at least 1947, when researchers from the Rockefeller Foundation put a rhesus monkey in a cage in the middle of Zika Forest of Uganda. The team was conducting surveillance for yellow fever. But “Rhesus 766” would ultimately become the first known carrier of Zika virus.
Symptoms are mild — a fever, joint pain, sometimes a rash or pink eye — but the disease typically clears within a week.
Zika’s cousin, chikungunya virus has also been associated with microcephaly. An abnormal smallness of the head, a congenital condition associated with incomplete brain development.
Microcephaly (my-kroh-SEF-uh-lee) is a rare neurological condition in which an infant’s head is significantly smaller than the heads of other children of the same age and sex. Sometimes detected at birth, microcephaly usually is the result of the brain developing abnormally in the womb or not growing as it should after birth.
Microcephaly can be caused by a variety of genetic and environmental factors. Children with microcephaly often have developmental issues. Generally there’s no treatment for microcephaly, but early intervention with supportive therapies, such as speech and occupational therapies, may help enhance your child’s development and improve quality of life.
CDC Q&A
Is there a vaccine to prevent or medicine to treat Zika?
No. There is no vaccine to prevent infection or medicine to treat Zika.
I am pregnant. Should I travel to a country where cases of Zika have been reported?
Until more is known, CDC recommends special precautions for pregnant women and women trying to become pregnant:
Pregnant women in any trimester should consider postponing travel to the areas where Zika virus transmission is ongoing. Pregnant women who do travel to one of these areas should talk to their doctor or other healthcare provider first and strictly follow steps to avoid mosquito bites during the trip.
Women trying to become pregnant or who are thinking about becoming pregnant should consult with their healthcare provider before traveling to these areas and strictly follow steps to prevent mosquito bites during the trip.
Because specific areas where Zika virus transmission is ongoing are difficult to determine and likely to change over time, CDC will update this travel notice as information becomes available. Check CDC’s Zika Travel Information website frequently for the most up-to-date recommendations.
I am pregnant. How will Zika virus affect me or my unborn baby?
CDC has issued a travel notice (Level 2-Practice Enhanced Precautions) for people traveling to regions and certain countries where Zika virus transmission is ongoing.
This notice follows reports in Brazil of microcephaly and other poor pregnancy outcomes in babies of mothers who were infected with Zika virus while pregnant. However, additional studies are needed to further characterize this relationship. More studies are planned to learn more about the risks of Zika virus infection during pregnancy.

Is it safe to use an insect repellent if I am pregnant or nursing?
Yes. Using an insect repellent is safe and effective. Pregnant women and women who are breastfeeding can and should choose an EPA-registered insect repellents and use it according to the product label.
If a woman who is not pregnant is bitten by a mosquito and infected with Zika virus, will her future pregnancies be at risk?
We do not know the risk to the infant if a woman is infected with Zika virus while she is pregnant. Zika virus usually remains in the blood of an infected person for only a few days to a week. The virus will not cause infections in an infant that is conceived after the virus is cleared from the blood. There is currently no evidence that Zika virus infection poses a risk of birth defects in future pregnancies. A women contemplating pregnancy, who has recently recovered from Zika virus infection, should consult her healthcare provider after recovering.
Should a pregnant woman who traveled to an area with Zika virus be tested for the virus?
See your healthcare provider if you are pregnant and develop a fever, rash, joint pain, or red eyes within 2 weeks after traveling to a country where Zika virus cases have been reported. Be sure to tell your health care provider where you traveled.
Can a previous Zika virus infection cause someone who later becomes pregnant to have an infant with microcephaly?
We do not know the risk to the baby if a woman is infected with Zika virus while she is pregnant. However, Zika virus infection does not pose a risk of birth defects for future pregnancies. Zika virus usually remains in the blood of an infected person for about a week. The virus will not cause infections in a baby that is conceived after the virus is cleared from the blood.
Is it safe to get pregnant after traveling to a country with Zika virus?
If infected, Zika virus usually remains in the blood of an infected person for about a week. The virus will not cause infections in a baby that is conceived after the virus is cleared from the blood.
Can a pregnant woman be tested for Zika weeks or months after being in a country with Zika?
At this time, and for several reasons, we do not recommend routine Zika virus testing in pregnant women who have traveled to a country with known transmission. First, there can be false-positive results due to antibodies that are made against other related viruses. Second, we do not know the risk to the fetus if the mother tests positive for Zika virus antibodies. We also do not know if the risk is different in mothers who do or do not have symptoms due to Zika virus infection.
If a woman who has traveled to an area with Zika virus transmission, should she wait to get pregnant?
We do not know the risk to an infant if a woman is infected with Zika virus while she is pregnant. Zika virus usually remains in the blood of an infected person for only a few days to a week. The virus will not cause infections in an infant that is conceived after the virus is cleared from the blood. There is currently no evidence that Zika virus infection poses a risk of birth defects in future pregnancies. A women contemplating pregnancy, who has recently travelled to an area with local Zika transmission, should consult her healthcare provider after returning.
