True or False: Infection with a pathogen (a disease-causing microbe) does not necessarily lead to disease.
-
Correct!
Infection occurs when viruses, bacteria, or other microbes enter your body and begin to multiply. Disease follows when the cells in your body are damaged as a result of infection, and signs and symptoms of an illness appear.
