Health data released Friday, shows Zika cases are growing in Southern California and throughout the state, where two babies have been born with virus-related defects.

The number of people reported to have Zika infections in the U.S. more than doubled in the past six weeks – from 935 as of June 29 to 1,962 – and tripled in U.S. territories from 2,026 to 6,618, the Centers for Disease Control and Prevention reports.

California’s cases – all travel-related – rose from 114 reported July 29 to 153 reported Friday, the California Department of Public Health reported.

The first two babies born in the state with Zika-caused microcephaly, or abnormally small heads, were reported Aug. 4.

Los Angeles, with the state’s highest case number, grew from 24 reported July 29 to 34. Orange County has 10.

Riverside County, after reporting its first Zika infection July 5 and a second Wednesday, now has five travel-related cases. San Bernardino County, which reported its first case in March, has seven.

The state apparently ranks third in the number of infected people here, behind New York at 530 and Florida with 322, according to the Centers for Disease Control and Prevention.

But those and U.S. numbers may be low and outdated. The CDC reported California had 87 cases as of Aug. 10. The state already has reported dozens more cases.

The CDC lists Texas, which reported its first Zika-related infant death Tuesday, Aug. 9, with 99. The Texas Department of State Health Services reported 106 Friday.

San Diego County, with 28 cases, has the state’s second-highest number.
