Infection or colonization, contrary to what many people think, does not necessarily imply immediate damage to the host. From birth, beneficial microorganisms coexist and develop within us for a long time. However, when such organisms cause damage to the host body, an infectious disease with the associated symptoms and pathology is contracted. From a clinical point of view, a pathogen is any microorganism capable of developing as an infectious disease; where differences in pathogenicity depend on virulence. Infectious diseases caused by pathogenic microorganisms, such as bacteria, viruses, parasites or fungi can spread, from person to person, directly or indirectly and throughout a community.
