Can a previous Zika virus infection cause someone who later becomes pregnant to have an infant with microcephaly?

We do not know the exact risk to the baby if a woman is infected with the Zika virus while she is pregnant. However, Zika virus infection does not pose a risk of birth defects in 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.
