What are airborne precautions?

Airborne precautions are specific infection control practices designed to prevent the transmission of diseases that are spread through tiny droplets or dust particles that remain suspended in the air for extended periods. These precautions are essential for protecting healthcare workers, patients, and visitors from diseases such as tuberculosis, measles, and chickenpox, which can be easily dispersed in the air and inhaled by individuals who are not infected.

Implementing airborne precautions involves several key measures, including the use of specialized respirators or masks (such as N95 respirators), isolating infected patients in negative pressure rooms, and ensuring proper ventilation in care areas. These steps are critical in minimizing the risk of airborne transmission in healthcare settings.

The other options do not pertain to airborne precautions. Measures taken to prevent foodborne illnesses focus on food safety, while safety regulations for handling waste deal with environmental and health hazards associated with waste materials. Guidelines for personal hygiene relate to general cleanliness practices rather than specific airborne transmission prevention strategies. Thus, the correct answer accurately reflects the purpose and nature of airborne precautions.
