 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 In this article, we explain the different types of infections, how to reduce the risk of infection, and what symptoms they cause. The immune system is an effective barrier against infectious agents. However, pathogens may sometimes overwhelm the immune system’s ability to fight them off. At this stage, an infection becomes harmful. Some pathogens have little effect at all. Others produce toxins or inflammatory substances that trigger negative responses from the body. This variation means that some infections are mild and barely noticeable, while others can be severe and life threatening. Some pathogens are resistant to treatment. Bacteria, viruses, fungi, and parasites are different types of pathogens. They vary in several ways, including: size shape function genetic content how they act on the body
