San Francisco Health Officials Investigate Two Active Tuberculosis Cases at Mid-Market Strip Club
Two active cases of tuberculosis linked to The Crazy Horse strip club on mid-Market Street have triggered an ongoing public health investigation, SFGATE reported. The San Francisco Department of Public Health confirmed it was notified of the first infection in early October. Health officials have initiated contact tracing to identify individuals who may have been exposed, though the agency stated that the risk to the general public remains low.
Public Health Officials Trace Exposures Amid Low General Risk
The San Francisco Department of Public Health launched its inquiry after receiving notice of the initial case in October. City health teams are actively tracing contacts associated with the venue, located at 980 Market Street next door to the Warfield Theater. While officials have not disclosed whether the infected individuals were employees or patrons of the establishment, they emphasize that public risk is minimal and that updates will be issued if the situation changes. NBC Bay Area noted that the venue has operated at the location for more than three decades.
Medical Experts Explain Airborne Transmission and Testing Delays
Tuberculosis is an infectious bacterial disease that primarily attacks the lungs and spreads through the air when an infected person coughs, releases microscopic particles, or in a poorly ventilated room. Dr. Monica Gandhi, an infectious disease expert at UC San Francisco, explained that the bacteria can linger in the air even after an infected person has left a room. Dr. Abraar Karan, a member of the Infectious Diseases faculty at Stanford University, added that crowded spaces with poor ventilation heighten transmission risks. Furthermore, Dr. Peter Chin-Hong, a professor of medicine and infectious disease specialist at UCSF, cautioned that contact tracing teams will need time to monitor potential cases because tuberculosis bacteria grow very slowly. Consequently, initial tests might yield negative results before turning positive weeks later if an infection truly occurred.
City Tuberculosis Rates Exceed State Averages Following Prior Outbreaks
The current investigation unfolds against a backdrop of elevated tuberculosis incidence in San Francisco. In 2025, the city recorded an incidence rate of 9.3 TB cases per 100,000 people, significantly higher than the California state average of 5.4 cases per 100,000 people, according to data from the San Francisco Department of Public Health and the California Department of Public Health. San Francisco typically logs between 60 and 90 active cases annually, with 68 cases reported in 2025, primarily among non-U.S.-born residents. Last fall, a separate outbreak at Archbishop Riordan High School resulted in eight active cases and 244 latent infections.
Health Department Can Compel Treatment for Active Tuberculosis
Both latent and active forms of tuberculosis are curable, though treatment requires a lengthy course of antibiotics that can prove difficult for patients to complete. Unlike latent tuberculosis—which remains asymptomatic and non-contagious—active tuberculosis brings severe symptoms including persistent coughing, fever, night sweats, and weight loss. Because of the public health threat posed by active transmission, the health department holds the legal authority to compel exposed individuals to undergo testing, receive treatment, or remain in isolation.
