which mode of transmission spreads disease through droplets in a sneeze or cough?
Understanding how diseases can spread makes them easier to prevent. What is Airborne Transmission? Airborne transmission occurs when bacteria or viruses travel on dust particles or on small respiratory droplets that may become aerosolized when people sneeze, cough, laugh, or exhale. They hang in the air much like invisible smoke. They can travel on air currents over considerable distances. These droplets are loaded with infectious particles.
