Two babies were born with Zika-related microcephaly from mothers who were infected with the virus, the California Department of Public Health announced Thursday.
The women were infected from traveling to countries where the disease was endemic, according to the CDPH. The department said it would not release any additional information to protect the privacy of the families.
â€œThis is a sobering reminder for Californians that Zika can cause serious harm to a developing fetus,â€ CDPH Director and State Health Officer Dr. Karen Smith said.
As of July 28, 15 babies have been born with Zika-related birth defects, according to the Centers for Disease Control and Prevention. In California, 114 people were infected with the virus, including 21 pregnant women, the CDPH said. All were travel-related, the department said.
Los Angeles County has the highest number of infected people in the state, 24, followed by San Diego County at 23.
The Zika virus outbreak was first reported in Brazil when an unusually high number of babies there were born with microcephaly. An international public health emergency was declared in February as the outbreaks spread to dozens of countries in the Americas.
