Two babies have been born with Zika-related birth defects in California to mothers who were infected in other countries, health officials said Thursday.
The newborns survived. One of the mothers returned to her home country with her baby while the other remains in the state, according to the California Department of Public Health.
Health officials declined to release additional details about the cases, citing patient privacy.
Nineteen other pregnant women in California who contracted Zika while traveling abroad were being monitored by doctors.
Babies born to Zika-infected mothers will be followed for up to a year. Health officials will check their hearing, vision and development, said Dr. Connie Mitchell, deputy director of the Center for Family Health.
