San Fernando Valley/Santa Clarita Valley Service Planning Area 2 Community and Field Services Team
Dr. Eric El-Tobgy and Service Planning Area (SPA) 2 District Public Health Nursing have been managing an outbreak of silico-TB affecting workers at engineered stone fabrication facilities in Los Angeles County (LAC). Silicosis is an irreversible fibrotic lung disease caused by the inhalation of silica dust which is produced in occupations involving stone or rock cutting, grinding, and crushing. Engineered stone products, such as kitchen countertops, are in high demand and there are many fabrication facilities in SPA 2. Silicosis and occupational silica exposure increases the risk of tuberculosis, over 20 times higher than in healthy individuals.
Since 2019, LAC has identified more than 250 individuals with silicosis. Among these workers, seven individuals with TB disease were identified between 2015 and 2025 with successful treatment occurring in six patients and 1 death. Seven worksite contact investigations (CIs) were conducted; 15 contacts with latent TB infection (LTBI) were identified. Those with signs or symptoms of TB and/or silicosis were referred for care.
SPA 2 faced worksites not consistently implementing engineering controls, such as the use of personal protective equipment and workplace monitoring, to reduce silica exposure and complex clinical diagnoses because silicosis and TB disease symptoms are similar. Increasing fear and mistrust of the government due to the current immigration climate also created challenges. Some contacts refused or were unable to complete their TB evaluations. There were also low LTBI treatment initiation and completion rates among contacts. A few of these contacts developed TB disease.
Despite these and other challenges impacting staffing and funding, Dr. El-Tobgy and SPA 2 Public Health Nurses remained vigilant and have been vital in addressing this newly recognized public health crisis. The district also partnered with a local community health organization, Pacoima Beautiful, to raise awareness and build trust between the health department and the community. It is likely that new cases of silicosis and TB will be identified in the coming years. SPA 2 has provided a framework for how to prevent an outbreak of silico-TB from becoming an even greater public health tragedy.

Mission Neighborhood Health Center
Mission Neighborhood Health Center (MNHC) has been a committed partner in the fight against tuberculosis (TB) in San Francisco’s Mission district for many years. Over a decade ago, MNHC launched a nurse follow-up program for patients with positive TB tests, ensuring they received comprehensive care, including diagnosis and preventive treatment. This initiative significantly improved patient outcomes and helped prevent the spread of TB within the community. We thank and appreciate MNHC for all of their hard work and contributions to TB prevention!

Her clinic adopted materials for status adjusters, and nearly 100% of patients received treatment referral information by year-end.

San Diego County TB Elimination Initiative Community of Practice (TBEI CoP)
The San Diego County TB Elimination Initiative Community of Practice (TBEI CoP) was established in October 2021 to promote the development and use of an LTBI care cascade across healthcare organizations in the county. Members, including healthcare providers and organizations, meet quarterly to share LTBI improvement projects, best practices, lessons learned, and data on their LTBI care cascades. TBEI CoP members are recognized as TB elimination heroes for initiating changes in their practices, such as presentations to decision-makers, EHR enhancements, LTBI coordinator positions, workflow improvements, telehealth integration, and provider education.
