New data shows 18%, or nearly 1 in 5, of tested students and staff at Archbishop Riordan High School in San Francisco were diagnosed with either latent or active tuberculosis during an outbreak that started in November.
New testing is scheduled to start today.
In total, 96% of the school community was tested, seven people were diagnosed with active cases during the course of the outbreak and 241 latent cases were reported, according to data released by the San Francisco Department of Public Health on April 27 to the school community.
In February, four active cases and three suspected active cases were reported. The latest numbers reflect the suspected cases were confirmed to be active TB. The entire school community went through another round of TB testing in March.
“Data from the March 2026 round of testing indicate a strong reduction in transmission,” the department said in an emailed statement to SFGATE Wednesday.
The department also stressed that “repeat mass testing at the school is no longer required.” They said the new testing is “out of an abundance of caution” and only for those who had a recent exposure to a confirmed case or were part of a “small group of individuals with new latent TB cases” found during the March testing.
Dr. Monica Gandhi, an infectious disease expert at UC San Francisco, explained that TB is a slow-growing disease, which means testing may not start for eight to 10 weeks after an exposure to active TB.
“Every time there’s an active case, you start the clock from there in terms of rounds of testing,” she told SFGATE in a phone call. “If that person was at school, then everyone around them needs contact tracing and testing again.”

I had latent TB for years. Didn’t know it. Wasn’t contagious. The antibiotics to cure it were brutal.
Another reason to not allow invasion of your country.
Forbes reports that ivermectin didn’t work against TB
18% prevalence of TB in a school and ongoing surveillance testing is not required? Did I miss something?
*cough*, *hack*, *wheeze*
That one was the first post of the SFGate article...if anything this thread gets deleted.

Lungers!
I expect this in San Francisco.
When I had the Whipple surgery in June 2024, the surgeon included IV Diflucan as an antifungal. That is considered first line treatment for Valley Fever. I later developed MRSA pneumonia and required vancomycin IV every 12 hours for 5 weeks to overcome it.
What’s next? Hantavirus, TB, Ebola?
When I was in med school we had almost eradicated TB in the US.
Then mass migration from the 3 rd world and AIDS fought it back.

When she was 12, my mother contracted TB and it almost killed her but she recovered. I acquired immunity from her, so I reacted positively to every skin test with dead TB in it.
How does a school system operate without testing for TB until 20% of the pupils are infected?
Oh, I forgot: illegals.
