  3. Areas with Zika

Zika virus is transmitted to people primarily through the bite of an infected Aedes species mosquito.

Through mosquito bites Mosquitoes become infected when they feed on a person already infected with the virus. Infected mosquitoes can then spread the virus to other people through bites.

From mother to child A mother already infected with Zika virus can pass the virus to her newborn during pregnancy or around the time of birth. If transmitted, the baby may develop brain abnormalities.

Through sexual contact
A man with Zika Virus symptoms can pass the virus to his sex partners before symptoms start and after symptoms resolve. The virus is present in semen longer than blood.

Through infected blood
At this time there are no cases related to blood transfusions in the U.S, however there are reported cases in Brazil.

Pregnant Women
Men who reside in or have traveled to an area of active Zika virus transmission who have a pregnant partner should abstain from sexual activity or consistently and correctly use condoms during sex (ie. vaginal intercourse, anal intercourse or fellatio) for the duration of the pregnancy.

Non-Pregnant Partners
Men who reside in or have traveled to an area of active Zika virus transmission who are concerned about sexual transmission of Zika.
