“The San Francisco Department of Public Health is investigating an active outbreak of tuberculosis at a local high school that has sickened at least three individuals. In an emailed statement to SFGATE, department officials said all students and staff at Archbishop Riordan High School are being tested for TB and they have implemented contact tracing to stop the outbreak from spreading. … Tuberculosis is a bacterial disease that can cause cough, fever and weight loss, and can progress into severe symptoms if untreated. A person can have a latent form of the disease, where they have no symptoms, or active TB, where they have symptoms and are infectious. The latent form can switch to active at any time.” (01/28/26)
