Latent tuberculosis infection

A latent (inactive) tuberculosis (TB) infection is the presence of TB bacteria in a person's lungs even though they do not have symptoms of TB (such as coughing, weight loss, fatigue, or fever).

A person with latent tuberculosis infection has no signs of active TB on a chest X-ray, and no TB-causing bacteria can be found in the mucus from the person's lungs (sputum). The only proof that the person has a TB infection is a positive TB skin test or TB blood test (interferon-gamma release assay or IGRA).

People who have a latent TB infection do not spread the disease to other people. They may need to take medicine to prevent the bacteria from becoming active in the future.

Due to the threat of the COVID-19 (Coronavirus), we are taking precautionary measures to protect our staff and patients. We are implementing a temporary NO VISITOR policy at this time. Only patients or patients and their guardians will be allowed into the office. Please note, this is not to inconvenience anyone! The virus is a very real threat and it is essential that we stay healthy in order to provide needed care for our patients. If you are sick, we ask that you CALL the office to speak with a nurse before you come in. The nurse will provide specific instructions for you. Please DO NOT enter the office if you are sick (upper respiratory symptoms, fever, cough, or flu like symptoms). We are closely monitoring the situation and will update you as circumstances change. Thank you for your understanding!!
