If a resident has latent TB infection (LTBI), what is the risk of transmitting TB to others in the facility?

In the case of latent TB infection (LTBI), the individual has been infected with the TB bacteria, but the bacteria remain inactive in the body, and the person does not exhibit symptoms or feel ill. This inactivity means that individuals with latent TB cannot transmit the bacteria to others, as the infection is not active. Unlike active tuberculosis, which involves symptomatic disease and can be transmitted through the air primarily when an infected person coughs or sneezes, those with LTBI are not contagious. As a result, the risk of transmission of TB to others in the facility is non-existent. This understanding is critical in infection control practices, as it helps to differentiate between those who need treatment and those who do not pose a risk to others.
