Final answer:
Tuberculosis (TB) is transmitted through the airborne route, as the bacteria are spread when an infected person coughs, sneezes, or spits and others inhale these bacteria.
Step-by-step explanation:
The mode of transmission for tuberculosis (TB) is airborne. Tuberculosis bacteria are spread when an infected individual coughs, sneezes, or spits, and the bacteria are then inhaled by nearby individuals. This infection route is characterized by the inhalation of droplet nuclei containing tubercle bacilli, which enter the lungs and travel to the alveoli, potentially infecting the new host. It is important for the nurse to convey that tuberculosis is highly contagious and can be spread through the air, which differs from contact, droplet, or vector-borne transmission methods. Public health notices have historically reminded people of the dangers of TB and the ease with which it can be transmitted through the air.
