Dear Health Care Provider,

Thank you for your interest in the County of Orange HealthHealthcare Providers Care Agency Tuberculosis (TB) Control Program. TB remains one of the world’s deadliest diseases, with almost 2 million TB-related deaths worldwide every year. TB lies dormant in one in three people, and each year, over 9 million people around the world become sick with TB. In 2010, the United States and California continued to report a decline in the number of TB cases from the prior year. However, California continues to contribute the greatest number of TB cases to the nation’s total TB morbidity. More locally, in 2010, Orange County reported 224 TB cases, which represents an increase of 13.7 % from 2009 when 197 cases were reported (the first time the number of reported TB cases fell below 200 since 1979). This case increase shows that TB remains a significant problem in Orange County and we urge community health care providers to stay alert to the symptoms of TB disease in patients and to promptly diagnose and report patients with TB to our program. Without your continued support and collaboration, we cannot succeed in our efforts to reduce, and ultimately eliminate, TB in Orange County.

This website contains TB educational materials, including a list of clinic and laboratory services the Orange County TB Control Program provides, TB case reporting forms, and updated information on the diagnosis and treatment of latent TB infection and TB disease and the use of interferon-γ release assay (IGRA) tests.

Thank you again for your assistance and interest in protecting Public Health. Please do not hesitate to call me at (714) 834-8243, if you have questions or if I can be of further assistance to you.


Julie Low, MD
TB Controller,
County of Orange
