What is the transmission method for tuberculosis (Mycobacterium tuberculosis)?

The transmission method for tuberculosis (Mycobacterium tuberculosis) is airborne transmission. This means that the bacteria can be spread through tiny droplets when an infected person coughs, sneezes, or talks. These droplets can remain suspended in the air for extended periods and can be inhaled by individuals in the vicinity, potentially leading to infection.

Airborne transmission is particularly significant in enclosed spaces where ventilation is inadequate, as it facilitates the spread of the bacteria to susceptible individuals who are not in direct contact with the infected person. Understanding this transmission pathway is crucial for implementing effective infection control measures in settings like nursing homes, where vulnerable populations reside. Proper ventilation, the use of masks, and isolation of individuals with active tuberculosis are key strategies to prevent the spread of this airborne pathogen.
