An infection occurs when a microorganism enters a person’s body and causes harm.
The microorganism uses that person’s body to sustain itself, reproduce, and colonize. These infectious microscopic organisms are known as pathogens, and they can multiply quickly. Examples of pathogens include:
bacteria
viruses
fungi
They can spread in several different ways, including through:
skin contact
the transfer of bodily fluids
contact with feces
ingesting contaminated food or water
inhaling airborne particles or droplets
touching an object that a person carrying the pathogen has also touched
