Officials warn of tuberculosis exposure at a California Learn4Life charter school

"Innovation High School and county officials are warning of possible tuberculosis exposures at the charter school's Chula Vista learning center this summer. The county has worked with the school part of the Learn4Life network of charter schools to notify people at highest risk of infection and is offering free screenings for some students and staff. The exposure period was from June 1, 2025, to Sept. 4, 2025, county officials said Tuesday evening."

"Learn4Life schools are non-classroom-based, independent-study charter schools and serve some of the state's most vulnerable students. The Chula Vista learning center one of several that make up the San Diego charter school enrolls 430 students, but they're not all typically there at once. During a recent visit, a few dozen were working quietly with teachers, with each other or on their own, and teachers were holding two optional small-group classes."

"Tuberculosis spreads through inhalation of bacteria in the air when an infected person coughs, speaks, sings or breathes, county officials explained. Anyone with frequent or prolonged indoor exposure to an infected person should be tested, and brief interactions are less likely to lead to infection. Symptoms of active TB include persistent cough, fever, night sweats and unexplained weight loss, said Dr. Sayone Thihalolipavan, the county's public health officer."

Tuberculosis transmits when an infected person coughs, speaks, sings or breathes, and frequent or prolonged indoor exposure warrants testing. Symptoms include persistent cough, fever, night sweats and unexplained weight loss. Most infected people do not become immediately ill.
