What factor is associated with respiratory droplet transmission?

• A. Contamination of surface
• B. Close contact with infected persons
• C. Hand hygiene
• D. Air filtration systems

Answer: (B)

Respiratory droplet transmission refers to the spread of infectious agents through droplets expelled from the respiratory tract of an infected person, typically when they cough, sneeze, or talk. Close contact with infected persons is a primary factor in the transmission of respiratory diseases, as droplets can be inhaled by individuals nearby. This mode of transmission is significant in diseases such as influenza and COVID-19, where proximity plays a crucial role in the likelihood of infection. While contamination of surfaces, hand hygiene, and air filtration systems are important in infection control and reducing the overall risk of disease spread, they do not directly correlate with the mechanics of respiratory droplet transmission. Surface contamination relates more to contact transmission, hand hygiene is a preventive measure against various types of infections, and air filtration systems help reduce the concentration of airborne pathogens, but they do not establish the direct transmission pathway that occurs through close contact with an infected individual.
