350 Infants Possibly Exposed to Tuberculosis by California Hospital Employee, Says Hospital

Everyone who was potentially exposed has been identified, the hospital said.

The Santa Clara Valley Medical Center learned in mid-November that an employee who worked in the newborn nursery was suspected of having active tuberculosis, the hospital said in a news release Friday, and the employee was placed on leave.

Three-hundred fifty infants may have been exposed, the hospital said, adding that they will be monitored closely for signs.

"While the risk of infection is low, the consequences of a tuberculosis infection in infants can be severe," Dr. Stephen Harris, Chair of Pediatrics, said. "That's why we decided to do widespread testing and start preventative treatments for these infants as soon as possible."

Santa Clara Valley Medical Center said in a statement that it will "provide both diagnostic testing and preventative daily treatments of isoniazid, an antibiotic that kills tuberculosis and can successfully prevent infants from becoming ill."

Mothers and employees who may have also been exposed will be screened and give preventative treatment if needed, according to the hospital statement. Everyone who was potentially exposed has been identified, and the hospital is contacting all mothers who were in the Mother & Infant Care Center between mid-August and mid-November.

The Medical Center's employees undergo annual tuberculosis screening, and when the employee with TB underwent her screening in September, she tested negative, the hospital said. It was the employee's physician who discovered the TB when the employee underwent evaluation for an unrelated medical condition, the hospital statement said, adding that, "even before the hospital received a confirmed diagnosis, the employee was placed on leave."
