Tuberculosis is spread from one person to the next through the air when people who have active TB in their lungs cough, spit, speak, or sneeze. [1] [9] People with latent TB do not spread the disease. [1] Active infection occurs more often in people with HIV/AIDS and in those who smoke. [1]
Mycobacterium tuberculosis (M. tb), also known as Koch's bacillus, is a species of pathogenic bacteria in the family Mycobacteriaceae and the causative agent of tuberculosis. [ 1 ] [ 2 ] First discovered in 1882 by Robert Koch , M. tuberculosis has an unusual, waxy coating on its cell surface primarily due to the presence of mycolic acid .
Treatment of active TB disease is typically a combination of antibiotics, which results in patients being non-infectious to others usually within a few weeks. Until that point, though, patients can spread TB to others and it’s typically adults with reactivated TB that are the most infectious.
Miliary tuberculosis is a form of tuberculosis that is characterized by a wide dissemination into the human body and by the tiny size of the lesions (1–5 mm).

It is intended to be posted outside rooms of patients with an infection that can spread through airborne transmission. [1] Video explainer on reducing airborne pathogen transmission indoors Airborne transmission or aerosol transmission is transmission of an infectious disease through small particles suspended in the air.

Latent tuberculosis (LTB), also called latent tuberculosis infection (LTBI) is when a person is infected with Mycobacterium tuberculosis, but does not have active tuberculosis (TB). Active tuberculosis can be contagious while latent tuberculosis is not, and it is therefore not possible to get TB from someone with latent tuberculosis.
