Officials and multiple outlets report that 19 Legionella infections are linked to Kaiser Permanente Santa Clara Medical Center, where additional water treatment measures were taken while investigators look for the source.
Public health officials are investigating a Legionella outbreak linked to Kaiser Permanente Santa Clara Medical Center after reporting rose to 19 confirmed infections.
The Los Angeles Times reported on May 18 that 19 Legionella cases were linked to the Bay Area hospital. Earlier coverage had put the count at 18 as investigators worked to identify the source of the bacteria.
Kaiser previously said it had taken additional water treatment and preventive measures at the Santa Clara medical center. Officials have not yet identified the source of the contamination.
Legionella can grow in human-made water systems and can cause Legionnaires' disease, a serious type of pneumonia, according to the California Department of Public Health.
The latest reporting does not specify whether the 19 cases are patients, staff members, visitors, or a mix. Investigators are still looking into how the outbreak spread and whether more cases will be confirmed.
