Health Advisory: Tuberculosis Response Update

The San Francisco Department of Public Health (SFDPH) has released an updated status report regarding the tuberculosis (TB) outbreak at Archbishop Riordan High School. As of February 21, 2026, health officials have confirmed 204 cases of latent TB among the school community following the testing of over 1,200 students and staff. Dr. Susan Philip, the City’s Health Officer, emphasized that latent TB is not contagious and that the risk to the general public remains low.

According to the official notice, 99% of students and 100% of faculty have completed the necessary TB clearance protocols. While the school has returned to in-person instruction, SFDPH continues to monitor the situation and provide treatment guidance for those with latent infections to prevent the development of active disease.
