The definition of airborne diseases has been changed by the World Health Organization

WHO is opening up the definition of airborne pathogens to include when respiratory droplets spread through the air and when they land on a person, regardless of the size of the droplet. The definition will also include when the droplets land on someone, not when they are in contact with each other.
