1. When am I required to report a suspected case of active TB disease to PHSKC TB Control Program? Is extrapulmonary TB disease also a reportable condition?

Healthcare providers are required to report suspected cases of active pulmonary TB disease and extrapulmonary TB disease to us within 24 hours. We request that healthcare providers contact us when empiric treatment for active TB is considered. If you start someone on TB medication for suspected active TB disease, you must report the case to us. PHSKC TB Control Program manages all cases of active pulmonary TB disease in King County. If the patient lives outside of King County, please report the case of TB to the appropriate county per the patient’s address.

2. Is culture confirmation required before reporting a suspected case of active TB disease? What if I start patients on treatment for suspected TB disease?

No, culture confirmation is not required before reporting the case.

6. How do I differentiate between active TB disease and latent TB infection?

Please see the chart below for key differences in active TB disease vs. latent TB infection. You may request a consultation with us for help with active TB rule out, or question about active TB disease vs. LTBI.

Latent TB Infection Active TB Disease
  • No symptoms or physical findings suggestive of TB disease
  • TB blood test or TST result usually positive
  • Chest radiograph is typically normal
  • If done, respiratory specimens are smear and culture negative
  • Cannot spread TB bacteria to others
  • Should consider treatment for LTBI to prevent TB disease
  • Symptoms may include one or more of the following: fever, cough, chest pain, weight loss, night sweats, hemoptysis, fatigue, and decreased appetite
  • TB blood test or TST usually positive
  • Chest radiograph is usually abnormal, buy may be normal in people with advanced immunosuppression or extrapulmonary TB disease
  • Respiratory specimens are usually smear and/or culture positive, but may be negative in people with extrapulmonary TB disease or minimal/early pulmonary TB disease
  • Can spread TB bacteria to others
  • Needs treatment for TB disease

7. Where do I find patient or provider educational resources about active TB disease or latent TB infection?

Please email us at LTBI@kingcounty.gov and we will help you find appropriate educational materials, including patient education materials in their preferred language.

8. Where can I connect with TB experts and other local providers who treat patients with TB?

In addition to the services that we provide for patients who are highly suspected of having infectious active TB, or who are diagnosed with active TB disease, the TB Control Program provides the following LTBI (latent TB infection) services.

Tuberculin skin test (TST), or QuantiFERON (QFT) if appropriate, for:

  1. Close contacts of a recent infectious TB case ("significant TB exposure" defined by the Program)
  2. Immigrants with "Class B1" status (abnormal chest X-rays consistent with pulmonary TB, identified through immigration screening process)

CXR for:

  1. Close contacts who are:
    1. TST or QFT positive, or
    2. Children under 5 years old or severely-immunocompromised requiring window period prophylaxis after significant TB exposure (e.g., HIV infection, organ transplant, certain immunosuppressive medications.)
  2. Close contacts who have compatible symptoms of active TB.
  3. Selected cases with approval of a TB Program physician

Treatment of LTBI: individuals with latent TB infection who are also:

  1. Contacts of a recent infectious case ("significant TB exposure" occurred within the past 2 years.)
  2. Persons with Class B status who are at high risk of progression to active infectious TB.
