In California, an estimated 2 million people are living with Latent Tuberculosis Infection (LTBI), with 674,425 individuals in Los Angeles County alone. Since 85% of TB cases in the state are due to the reactivation of LTBI, diagnosing and treating LTBI is crucial to preventing active TB. However, only about 13% of those with LTBI in California receive treatment, leaving a significant opportunity to reduce TB transmission.

The Southern California Community of Practice to End TB is a forum for healthcare providers, clinics, healthcare systems, and public health agencies to work together to scale up LTBI diagnosis and treatment and to facilitate tracking community progress towards TB elimination.
