CHULA VISTA, CA - Wednesday, March 18th, 2026 - The San Diego County Public Health Services is currently investigating a potential tuberculosis (TB) exposure incident at Chula Vista High School, sending ripples of concern through the South Bay community. The exposure window, according to the County, spans from February 27th to March 12th, 2026, meaning students, faculty, and staff who were present during that period may have been at risk.

The County Health Services is working closely with the school administration to identify and notify potentially affected individuals. While authorities emphasize the risk to the wider public remains low, the situation underscores the ongoing challenges of infectious disease control within school environments and the importance of proactive public health measures.

"We understand that this news can be concerning, and we want to assure the community that we are taking this matter seriously," stated a spokesperson for the San Diego County Public Health Services in a press briefing earlier today. "Our priority is to quickly and efficiently identify anyone who may have been exposed and provide them with the necessary testing and, if required, treatment."

Free TB testing is being offered to individuals who attended Chula Vista High School during the specified timeframe. Details regarding testing locations, schedules, and necessary precautions can be found on the County's dedicated website: [ https://www.sandiegocounty.gov/content/sdc/hhsa/programs/tb/ ].

Understanding Tuberculosis: A Persistent Threat

Tuberculosis is an infectious disease, primarily affecting the lungs, but capable of spreading to other organs. It's caused by bacteria called Mycobacterium tuberculosis. The disease is spread through the air when a person with active TB coughs, sneezes, speaks, or sings, releasing tiny droplets containing the bacteria. These droplets can remain suspended in the air for hours, potentially infecting those who inhale them.

There are two primary forms of TB: latent TB infection and active TB disease. In latent TB, the bacteria are present in the body but inactive, causing no symptoms and being non-contagious. However, latent TB can develop into active TB disease if the immune system weakens. Active TB disease causes symptoms like persistent cough (sometimes producing blood), fever, night sweats, weight loss, and fatigue.

Increased Vigilance in Schools and the California Landscape

The Chula Vista High School incident isn't an isolated event. Public health officials have noted a slight uptick in reported TB cases across California in the past year, prompting increased surveillance and preventative measures. While California has historically had a higher rate of TB than most other states due to factors like a large foreign-born population (many from countries with higher TB prevalence), the recent increase has raised concerns.

Schools, in particular, present unique challenges for TB control. Close proximity between students, shared spaces, and potential delays in reporting symptoms can all contribute to the spread of the disease. Regular screenings, improved ventilation systems, and heightened awareness among school staff are vital for mitigating risk.

County Response and Future Preventative Measures The County's response extends beyond just testing those potentially exposed at Chula Vista High School. Health officials are also reviewing TB screening protocols within the school system and exploring options for improving ventilation in classrooms. They emphasize the importance of early detection and treatment, stating that active TB disease is curable with a course of antibiotics.

"We're committed to protecting the health of our community, and that includes proactively addressing potential outbreaks like this one," the County spokesperson added. "We encourage anyone experiencing symptoms of TB to seek medical attention immediately."

The County Health Services also reminds the public that individuals born or who have spent significant time in countries with high TB rates should be screened for latent TB infection, even if they are asymptomatic. This preventative measure can help stop the progression of the disease and prevent future outbreaks.
