Tuberculosis Client Services

World TB Day 2023
To our healthcare colleagues and partners,

Contra Costa Public Health’s Tuberculosis (TB) Client Services would like to take this opportunity to recognize all of you for the hard work and dedication you have shown in working toward Tuberculosis (TB) elimination in our county. We could not do our work without all of you. Together we are an amazing team.

World TB Day, March 24, is a global occasion on which people impacted by TB infection and disease, health professionals, advocates, media, general public, and government organizations unite in the fight against this disease.

Here are a few important key messages to consider in the year ahead.
  • One fourth of the world's population is infected with TB.
  • Two million Californians are infected with TB. Most don’t know it.
  • One out of six Californians diagnosed with TB disease die within five years.
  • TB is preventable
  • TB is curable.

TB Client Services is pleased to share important information about how we, along with the help of our community partners, healthcare providers and client families, control and strive to eliminate TB in our county.

TB is transmitted from person to person through the air when a patient with active TB disease coughs, sneezes or speaks. Because it is air-borne, it is especially important for those living in or traveling to a TB risk area to be aware that they are at risk for the disease, to know the symptoms of TB and to be tested, if they think they have been exposed.

Most people who are infected with the TB germ do not have the active form of the disease. They have no symptoms and are not infectious. However, they carry the germ, which may grow and lead to the active, infectious disease at some time in the future.

What are the symptoms of TB?

Symptoms of TB disease typically include a cough, lasting more than three weeks, accompanied by unintentional weight loss of at least 10 pounds, fevers and night sweats. It is essential for anyone with TB symptoms to consult a health care provider to find out if they have the active disease.

How do you know if you have TB?

TB infection can be diagnosed with two types of tests: a TB skin test (TST), also called a PPD; and one of two blood tests, called IGRAs. We recommend a blood test for anyone who has had a BCG vaccination. If someone has TB infection, but not active TB disease, it can be treated with a special medicine, called INH, taken for 9 months. Consult your health care provider about whether you should have a TB test, and which test is the best for you.
