Four ways that pathogens can infect humans is by :
-passing from one person to another with physical contact, like sexual contact or high-fiving
ex: if you kiss someone, they possibly have an open cold sore, and cold sore viruses are able to get into your body
-pathogens can also infect the human without direct contact
as if a person sneezes, the pathogens spread out and get shot into the air
inhaling oxygen can also cause humans to be infected, if someone currently has a sickness (cold or cough) other people will be able to catch the sickness that contains pathogens
so basically... sexual contact, greetings with hands, inhaling oxygen containing sickness, or sickness getting shot into the air.
HOPE THIS HELPED THANKS!

in bad ways
The typical ways are airborne, blood borne, vector borne, direct contact and indirect contact.
Microorganisms in food may cause harm by carrying disease-producing bacteria called pathogens. Pathogens harm humans in many different ways. The most common way that pathogens harm animals is by using toxins.
Direct contact includes touching, biting, kissing, and sexual contact.
By plane, by train, by boat, and by car.
Inject them? i dno, loads of ways!
Direct contact, indirect contact, airborne are ways pathogens are spread.
