An infectious disease agent can be transmitted in two ways: as horizontal disease agent transmission from one individual to another in the same generation (peers in the same age group) [3] by either direct contact (licking, touching, biting), or indirect contact through air – cough or sneeze (vectors or fomites that allow the transmission of the agent causing the disease without physical ...
By contrast, a limited number of diseases can be spread through airborne transmission after the respiratory droplet dries out. [14] We all continuously breathe out these droplets, but in addition some medical procedures called aerosol-generating medical procedures also generate droplets. [6]
