Definition of Suspected Tuberculosis

A suspected case of tuberculosis can be defined as any person who, based on clinical or epidemiological evidence, has a reasonable likelihood of having active tuberculosis whether started on antitubercular therapy or not. These persons must be reported to the Department of Public Health within one working day of suspicion. Examples of suspected cases include:

  • Any person with clinical or laboratory evidence consistent with active tuberculosis, even if the diagnostic evaluation is incomplete or culture results pending
  • Any person who has been started on anti-tuberculosis therapy for suspicion of active tuberculosis.
  • Any person with findings consistent with active tuberculosis, unless other clinical evidence make a diagnosis of tuberculosis unlikely.

Most statute regarding tuberculosis in California is found in the California Health and Safety Codes Sections 121350 – 121555. Click on the following link for the California Health and Safety Codes: SECTION 121350-121460.

Testing for TB in BCG-Vaccinated Persons (from www.cdc.gov)

Many people born outside of the United States have been BCG-vaccinated.

People who have had a previous BCG vaccine may receive a TB skin test. In some people, BCG may cause a positive skin test when they are not infected with TB bacteria. If a TB skin test is positive, additional tests are needed.

IGRAs, unlike the TB skin tests, are not affected by prior BCG vaccination and are not expected to give a false-positive result in people who have received BCG.
