Several factors contribute to the likelihood and extent of airborne transmission. These include:
Ventilation: Environments with poor ventilation facilitate the accumulation and persistence of infectious aerosols. Humidity and Temperature: These can affect the stability and dispersion of airborne particles. Duration of Exposure: Prolonged exposure to an environment with infectious aerosols increases the risk of infection. Activities: Activities that generate more respiratory aerosols, such as singing, shouting, or exercising, can enhance transmission.
