Droplet transmission

Definition

Droplet transmission involves the spread of pathogens via respiratory droplets, which are expelled when an infected person coughs, sneezes, or talks. These droplets can infect others when they come into contact with mucous membranes.

5 Must Know Facts For Your Next Test

1. Droplets typically travel less than 1 meter from the source and settle quickly due to gravity.
2. Common diseases transmitted this way include influenza, common cold, and COVID-19.
3. Preventive measures include wearing masks and maintaining physical distance.
4. Droplets are larger than 5 micrometers in diameter.
5. Transmission occurs primarily through close contact with an infected individual.
