Health Alert: Exposure to Drug-Resistant Tuberculosis at Southwestern Community College
4/14/2026, 7:11:35 AM
Overview of the Exposure Incident
A health alert has been issued for Southwestern Community College in Chula Vista, California, following the revelation that students and staff may have been exposed to a multidrug-resistant strain of tuberculosis (MDR-TB). San Diego County health officials announced the warning on Thursday, indicating that anyone who was on campus between late October and mid-December 2025 could potentially carry this dangerous strain. MDR-TB is a severe form of tuberculosis that does not respond to standard antibiotics, complicating treatment.
Health Officials' Response
Health officials are actively working to identify and notify individuals who may have been exposed. San Diego Public Health Officer Sayone Thihalolipavan emphasized the importance of early screening, stating, “The good news is that TB, including MDR-TB, is treatable and curable with the right medication.” The disease is airborne, spreading through coughs, speech, or even breathing, which raises concerns in crowded environments like classrooms.
Implications of Latent Tuberculosis
Individuals who test positive for tuberculosis but exhibit no symptoms may have latent TB, where the bacteria are present but inactive. Health officials warn that without treatment, approximately 5% to 10% of latent cases can progress to active TB. The delayed detection of TB cases is particularly concerning, as the disease can remain undiagnosed for months, allowing for silent transmission. In San Diego County, an estimated 175,000 individuals are living with latent TB infections, highlighting the prevalence of this underlying condition.
Rising Tuberculosis Cases
The warning comes amid a backdrop of increasing tuberculosis cases in the region, with hundreds of active cases reported annually. Despite the rise in overall TB cases, MDR-TB remains relatively uncommon, with only three reported cases in 2024 and two in 2025 within San Diego County.
Criticism & Opposition
Some health experts have raised concerns regarding the effectiveness of public health communication in addressing the risks associated with MDR-TB. Critics argue that more proactive measures should be taken to educate the public about the disease's transmission and the importance of screening, especially in high-density settings like educational institutions.
