What is a reservoir?

- Soilbourne/waterbourne.
What is a vector?
A living thing that transmits a pathogen from an infected host to a susceptible host.
What are airborne droplets?
Pathogens that can be transmitted inside airborne droplets that are sneezed or coughed into the air and are suspended for a period of time before being inhaled.
