What Is a Bacterial Infection?
2. How bacterial infections work
When we talk of bacterial infections, we are referring to the harmful kind that causes illness. If the body’s immune system and other interventions are unable to handle bacterial infections, it can lead to sepsis. Bacterial infections can occur on any part of the body including on the skin, in specific organs, and throughout the bloodstream. Some common infections include urinary tract infections (UTIs), the flu, and dental abscesses.
The harmful strains of bacteria that cause infections must find an entryway into the body as they come from the outside. Some harmful bacteria can be contracted through breathing in certain particles in the air. Others can enter through a cut in the skin or from food ingested. They can infect any part of the body and can be highly contagious, especially if airborne.
