Tuberculosis (TB) Information for Health Care Providers

The TB Prevention and Control Program investigates all reports of persons with confirmed or suspected TB disease in Santa Clara County. We provide individualized case management to each patient to help ensure treatment completion and to prevent TB from spreading further. We also provide consultation to medical providers and community partners. 

Tuberculosis Disease

Tuberculosis (TB) is a disease caused by a bacteria that is spread through the air from person to person. Although TB most often affects the lungs, it can affect any part of the body including lymph nodes, bones, kidneys, and the brain. TB can cause very severe illness and it can be fatal. Fortunately, TB can be prevented, treated, and cured.

Symptoms of TB can include fever, weight loss, night sweats, and fatigue. When TB affects the lungs, symptoms can also include a cough that lasts more than 2-3 weeks, coughing up blood, and chest pain. If you have any of these symptoms you need to see a doctor.

Populations at Risk
TB can infect anyone who lives, works, or breathes in close proximity to someone with infectious TB disease, regardless of their age, race, sex, or socioeconomic status. Over 90% of patients with TB disease in SCC were born outside of the U.S., though most have lived in the U.S. for more than 5 years. In SCC, the majority of cases occur among people born in Vietnam, the Philippines, India, and China.
