What are airborne-based transmission precautions primarily used to control?

  1. Infections from touching surfaces

  2. Transmission of diseases via inhalation over long distances

  3. Infections from food and drink

  4. Illnesses spread through skin contact

The correct answer is: Transmission of diseases via inhalation over long distances

Airborne-based transmission precautions are primarily used to control the transmission of diseases that can be inhaled and spread over long distances. This type of precaution is critical for managing infections caused by pathogens that can remain suspended in the air for extended periods and can be inhaled by individuals far from the source of infection. For example, diseases such as tuberculosis, measles, and chickenpox are transmitted through airborne particles, necessitating strict preventive measures in healthcare settings. These precautions often include the use of specialized air filtration systems, appropriate personal protective equipment (such as N95 respirators), and isolation of affected individuals in negative pressure rooms to minimize the risk of airborne spread to others. By focusing specifically on inhalation routes of transmission, healthcare providers can effectively reduce the incidence of these airborne infections in the community and healthcare institutions.
