What type of precautions is necessary for a patient suspected of having tuberculosis?

Droplet precautions are not sufficient for tuberculosis because the bacteria that cause this disease (Mycobacterium tuberculosis) are capable of remaining suspended in the air for extended periods. These bacteria are spread primarily through airborne particles that can be inhaled by individuals nearby. As a result, airborne precautions are necessary to prevent the transmission of tuberculosis to others.

In the context of patient care, airborne precautions involve the use of specialized masks (like N95 respirators) for healthcare workers and ensuring that the patient is in a negative pressure room, which helps to contain the airborne particles within a specific area. By employing these precautions, the risk of spreading the infection to others in the healthcare setting is minimized.

Understanding the specific type of precautions required for different diseases is crucial for healthcare workers, as it directly impacts patient and staff safety.
