TB is transmitted via which route?

Explanation:
TB spreads through the air as an airborne infection. When someone with active pulmonary TB coughs, sneezes, or even talks, they release tiny respiratory particles that become droplet nuclei. These small particles can linger in the air for hours and be inhaled by others, which can lead to infection in the lungs. This is why close, prolonged contact increases risk and why healthcare settings emphasize airborne precautions like N95 respirators and negative-pressure rooms. TB is not spread by water, touching shared objects, or food, so those routes don’t account for its transmission.
