Protect Your Health From Infections
What Is an Infection?
An infection is the growth of unwanted bacteria, viruses, or other one-celled organisms in the body. Infections interfere with normal body functions. Once an infection becomes established, you should contact a physician about possible medical treatment.
Viruses and bacteria are everywhere, but they do not always cause infections. An infection happens when a disease-causing organism enters a body system (e.g., respiratory, reproductive, or digestive system) where conditions allow it to live and multiply. Whether or not this happens depends on how the organism enters the body, what kind, how many viruses and bacteria are contacted, and the health of the person.
