Final answer:
Pathogens can be spread through airborne transmission, direct contact, and oral transmission.
Step-by-step explanation:
Pathogens can be spread from one person to another through a mode of transmission. There are several different modes of transmission, including:
- Airborne transmission: Pathogens in droplets expelled from an infected person's respiratory system can be inhaled by nearby people.
- Direct contact: Pathogens can spread through skin-to-skin contact or touching contaminated surfaces.
- Oral transmission: Pathogens can spread through direct oral contact, such as kissing, or sharing items that go in the mouth.
