Infectious aerosols are tiny particles or droplets that are capable of carrying pathogens, including viruses, bacteria, and fungi. These particles can be generated through various activities such as coughing, sneezing, talking, and even breathing. Their small size allows them to remain suspended in the air for extended periods, leading to the potential for widespread transmission of infectious diseases.
The transmission of infectious aerosols typically occurs through aerosol transmission. This can happen when an infected person releases respiratory droplets that contain pathogens into the air. These droplets can then be inhaled by others, leading to new infections. Enclosed spaces with poor ventilation increase the risk of aerosol transmission, making places like hospitals, schools, and public transport particularly vulnerable.
Key Factors Influencing Aerosol Transmission
Several factors influence the transmission of infectious aerosols:
