Will latent TB show up on CT scan?
Does latent TB show on CT scan?

Annual TB testing of health care personnel is not recommended unless there is a known exposure or ongoing transmission at a healthcare facility. Health care personnel with untreated latent TB infection should receive an annual TB symptom screen.
How is TB reactivation treated?
Nine months of isoniazid therapy is the treatment of choice for most patients with latent tuberculosis infection.
Where does TB reactivate?
Reactivation TB may occur if the individual’s immune system becomes weakened and no longer is able to contain the latent bacteria. The bacteria then become “active;” they overwhelm the immune process and make the person sick with TB.
