The Tuberculosis (TB) program for Mason County helps provide a healthier environment by reducing TB through education, identification, and prevention. This program provides case management to individuals with TB disease (active pulmonary TB) and high risk individuals positive for TB infection (latent TB). In the case of an active TB patient, directly observed therapy (DOT) is conducted for the full course of treatment. DOT means that a public health employee directly observes the patient taking all doses of medication. It also includes identification and screening of contacts, followed by contact treatment, if needed.
