LATENT TB INFECTION ACTIVE TB DISEASE Exposed to active TB disease, bacteria enters body but is controlled Infection has progressed to active disease, bacteria are multiplying Positive TB skin test No symptoms Will have symptoms Negative CXR Positive CXR WILL NOT INFECT OTHERS WILL
A TB skin test or PPD will show if you have any TB bacteria in your body. All employees or students that are potentially exposed to TB need to receive a skin test annually. How do we test for TB?
If patients have symptoms of TB, offer tissues and surgical masks. Escort patients to the nearest “negative pressure” room to isolate them. Patient should wear mask outside room and during transport to other departments All health care workers who work with potential TB patients should wear appropriate PPE when working with infectious individuals. How do Healthcare Workers avoid exposure to TB?
Remember your size Fit testing will be done annually for those performing high risk procedures Others will be done every 5 yrs unless there are facial changes. You will be asked about changes at your annual health update N-95 Respirator
Notify Prospective Health of facial changes: large amount of weight gain or loss facial trauma and/or surgery growth or shaving of beard If unable to wear mask, you will be instructed in the use of a PAPR N-95 Respirator

What if I have Latent TB Infection? 90% of healthy people with TB infection will never develop TB disease. Should be evaluated for prophylactic medications by the health department or a private physician.
