The categories of transmission-based precautions as defined by the Healthcare Infection Control Practices Advisory Committee (HICPAC) are specifically airborne, droplet, and contact precautions. These categories are designed to prevent the spread of infections based on the mode of transmission of pathogens.

Airborne precautions are implemented when pathogens can be transmitted through the air over long distances. This includes diseases like tuberculosis and measles. Healthcare workers and visitors are required to wear N95 respirators or other specialized masks when interacting with patients under these precautions.

Droplet precautions are necessary when pathogens are spread through large droplets that are expelled when a person coughs, sneezes, or talks. This includes infections like influenza and pertussis. In this case, masks should be worn when in close proximity to the patient.

Contact precautions are used for infections that can be transmitted through direct or indirect contact with the patient's environment or bodily fluids. This includes conditions such as MRSA and C. difficile. Gloves and gowns are emphasized in these situations to minimize the risk of transmission.

This classification system is essential in healthcare settings to implement the appropriate measures for infection control, protecting both patients and healthcare workers. The other options listed do not accurately represent the established categories of transmission-based precautions recognized by HICPAC.
