can be harmful: 1st situation
If normal flora microbes get somewhere in the body

be harmful: 2nd situation
If normal flora microbes reproduce too much and there

The person is capable of transmitting pathogens
to other people.

Carrier
Incubation period: the time between exposure
to the pathogens and first symptoms.
Symptoms: No Infectious: Yes Carrier: Yes

Illness: the person now has major symptoms.
Symptoms: Yes Infectious: Yes Carrier: No
3 stages of an infection: Stage 2
Convalescence: the symptoms are over, but the person
is still somewhat infectious.
Symptoms: No Infectious: Yes Carrier: Yes
3 stages of an infection: Stage 3
