What kind of transmission occurs in tuberculosis?

In tuberculosis (TB), the transmission occurs primarily through the airborne route, specifically via droplets released into the air when an infected person coughs, sneezes, or talks. These droplets can contain the bacteria that cause TB and can linger in the air for a period, allowing others who breathe in the contaminated air to become infected.

The airborne nature of TB emphasizes the importance of ventilation in living spaces and the need for measures such as wearing masks in high-risk environments to prevent the spread of the disease. Understanding this mode of transmission is crucial for public health measures and for nursing practice, where implementing infection control protocols is vital to protect healthcare workers and patients alike. Other forms of transmission, such as bloodborne or vector-borne, are not applicable to TB, thus highlighting why airborne transmission is the correct answer.
