Public health officials in Northern California are investigating a tuberculosis outbreak, identifying more than 50 cases at a private Catholic high school and ordering those who are infected to stay home. The outbreak comes as tuberculosis cases have been on the rise statewide since 2023. AdvertisementThe three cases of active TB have been diagnosed at the school since November, according to public health officials. School officials told NBC Bay Area news that in-person classes had been canceled and would resume Feb. 9, with hybrid learning in place until Feb. 20. Nationally, the rates of TB cases have increased in the years following the COVID-19 pandemic, which “was in some ways anticipated,” said Gohil.
