March 07, 2025 | Sacramento, CA — MedLegalNews.com — The new TB screening requirement in California took effect on January 1, 2025, aiming to reduce tuberculosis (TB) cases statewide. AB 2132, introduced by Assemblymember Evan Low (D-Silicon Valley), requires primary care providers to offer TB screening tests to adult patients if risk factors are identified and the test is covered by the patient’s insurance. Patients who test positive must receive appropriate follow-up care or a referral for treatment.
The implementation of the TB screening requirement in California marks a major step toward addressing the state’s persistent tuberculosis burden. Health officials emphasize that early detection of latent TB infections can significantly reduce the number of active cases each year. By integrating screening into routine primary care visits, the law promotes proactive prevention rather than reactive treatment, especially among communities at higher risk. This public health measure also aligns with California’s broader goal of achieving TB elimination through improved access, awareness, and coordinated care.
The Urgent Need for TB Screening
An estimated 2 million Californians are infected with TB, yet only 20% are aware of their diagnosis, and just 12% have received treatment. Every year, approximately 2,000 Californians develop active TB disease, and California’s TB incidence rate is nearly double the national average. TB Screening Requirement
Before the COVID-19 pandemic, TB was the leading infectious disease killer worldwide, claiming more than 1.5 million lives annually. In California, the disease disproportionately impacts communities based on race, ethnicity, and place of birth, underscoring the need for a health equity-driven approach to prevention.
Public health experts warn that without stronger preventive efforts, the state could see a resurgence of tuberculosis in vulnerable populations. The TB screening requirement in California is designed to close these treatment gaps by ensuring timely testing, follow-up, and education. By targeting high-risk groups—including immigrants, individuals with compromised immune systems, and those living in congregate settings—the initiative aims to curb transmission and reduce disparities in access to care.
Strengthening collaboration between local health departments, hospitals, and primary care providers will be essential to sustaining long-term progress in TB prevention and control.
The Role of Primary Care Physicians
With no effective TB vaccine, the best strategy for prevention is early detection and treatment of latent TB infection. The California Department of Public Health (CDPH), along with the CDC and the U.S. Preventive Services Task Force, strongly recommend that primary care physicians proactively screen at-risk patients.
To support providers, CDPH’s Tuberculosis Control Branch is hosting a free webinar on Thursday, April 24, from 12:00 – 1:30 p.m., covering best practices for TB screening and treatment. Register now to learn how to implement TB screening in your practice.
