The Marin County public health office is tracking an uptick in active tuberculosis cases in Marin.

The county had 13 reported cases in 2024, a 44% increase from the previous year. So far this year, 14 active cases have been confirmed, said Dr. Lisa Santora, the county’s public health officer.

No deaths were reported.

“It’s one of those diseases that people forget about,” Santora said. “They think it’s an old disease that doesn’t exist, and when we saw the data we thought it was a good time to issue an advisory.”

Tuberculosis is an airborne illness that typically affects the lungs, but it can affect other parts of the body such as the spine or kidneys, according to the federal Centers for Disease Control and Prevention.
