Confirmed Threat

The San Diego County Tuberculosis Program, working with San Diego City College and its Early Education Center, notified employees, students, and children that they may have been exposed to tuberculosis between September 15, 2023 and February 21, 2024 on the SDCC campus. The exposure was reported publicly on February 29, 2024 and was notable for involving both college-age students and children enrolled in the on-campus Early Education Center.

INITIAL ALERTEmail
The County Tuberculosis Program, San Diego City College (SDCC) and SDCC's Early Education Center (EEC) are working in close collaboration to notify employees, students and children potentially exposed to tuberculosis (TB) on the SDCC campus. The dates of potential exposure were from September 15, 2023, to February 21, 2024. Those known to have been potentially exposed were directly notified and provided direction from health officials. Exposures to the general public, most SDCC students and faculty, and other employees are believed to be limited. Tuberculosis is an airborne disease transmitted through inhalation of bacteria spread when someone sick with TB coughs, speaks, sings, or breathes. Symptoms of active TB include persistent cough, fever, night sweats, and unexplained weight loss. For more information, contact the County TB Control Program at (619) 692-8621.

This text has been reconstructed from news coverage and may not reflect the exact original wording.

The five-month exposure window (September 15, 2023 to February 21, 2024) spans two academic semesters and reflects the typical delay between TB infection, symptom onset, clinical diagnosis, and public health notification.
The involvement of the Early Education Center (EEC) -- an on-campus childcare facility -- was particularly significant because children are more vulnerable to TB disease progression than healthy adults.
The statement that exposure for 'most SDCC students and faculty' was 'believed to be limited' was a calibrated message designed to reassure the broader campus while still reaching those at genuine risk.
Context

Background

San Diego City College's February 2024 tuberculosis exposure notification was the second major TB alert at the institution in six years -- an earlier case had occurred in 2018. The 2024 case was unusual in several respects: the five-month exposure window was one of the longest publicly reported for a community college incident, and the involvement of the on-campus Early Education Center -- a licensed childcare facility -- meant that children, not just college students and employees, were potentially exposed. The county's TB Control Program managed direct outreach to identified contacts while issuing a public notice for anyone else who may have been on campus during the long exposure window. Community colleges in California's San Diego region have faced repeated TB exposure notifications partly because they serve large populations from communities with higher TB incidence, including recent immigrants from high-burden countries. NBC 7 San Diego reported that exposures to the general campus population were believed to be limited, with primary risk concentrated among those in prolonged indoor contact with the index case.
Analysis

Key Findings

The five-month exposure window (September 2023 to February 2024) reflects the typical but significant delay between TB diagnosis and public health notification
An on-campus Early Education Center (childcare facility) was included in the notification -- children face higher risk of TB disease progression than healthy adults
This was the second TB exposure notification at SDCC in six years (the earlier case was in December 2018), reflecting the recurrent exposure burden at urban California community colleges
The county TB Control Program managed targeted direct notification to identified contacts while issuing a broader advisory for the campus
Outcome
Those known to have been directly exposed were notified individually. Most SDCC students and faculty were considered to have limited exposure risk. The county TB Control Program managed testing and follow-up.
