Microcephaly is a birth defect in which a baby’s head is smaller than expected when compared to babies of the same sex and age. Babies with microcephaly often have smaller brains that might not have developed properly. Zika virus infection during pregnancy is a cause of microcephaly.
What does Zika do to babies?
In pregnant women, the virus can cause miscarriages, stillborn babies, or babies with birth defects. One serious birth defect caused by Zika is microcephaly. In microcephaly (the medical word for small head), a baby’s brain and skull don’t grow properly, so the baby will have severe developmental and health problems.
How is Zika passed to fetus?
Zika virus can be passed from a pregnant woman to her fetus. Zika primarily spreads through bites from infected mosquitoes. You can also get Zika through sex without a condom with someone infected by Zika, even if that person does not have symptoms of Zika. There is no vaccine to prevent or medicine to treat Zika.
When does Zika affect pregnancy?
Birth defects were reported in a higher proportion of babies whose mothers were infected with Zika virus during the 1st trimester (first three months) of pregnancy. In U.S. states, about 4 in 25 (15%) pregnant women with confirmed Zika virus infection in the 1st trimester had babies with Zika-associated birth defects.
Does Zika cause birth defects?
One of the devastating effects of the Zika virus is that it can cause severe birth defects such as microcephaly – a condition in which the head is underdeveloped – in children of pregnant women who are infected. But not all infected mothers experience such birth outcomes.
Is Zika still a threat 2020?

How long does Zika stay in sperm?
The CDC currently recommends that men who have traveled to a Zika-active region either use condoms or abstain from sex for at least 6 months. But that guideline is based on data showing that genetic traces of Zika virus can be found in semen 180 days after infection.
What viruses can cause birth defects?
Toxoplasmosis, cytomegalovirus (CMV), varicella, rubella, and lymphocytic choriomeningitis virus (LCMV) are among the agents that are recognized to have the potential to cause birth defects in a developing fetus.
Are Zika babies mentally challenged?
