About This Condition

Infection is the result of invasion of the body by microorganisms, including bacteria, viruses, or fungi.

Not all microorganisms cause infections in the body, and exposure to a disease-causing microorganism does not always result in symptoms. The immune system plays a large role in determining the body’s ability to fight off infection.

Some examples of infection are common cold/sore throat, influenza, cough, recurrent ear infections, urinary tract infection, yeast infection, athlete’s foot, cold sores, HIV, shingles, and parasites.


Symptoms of infection include localized warmth, redness, swelling, discharge, foul-smelling odor, and pain to the touch. In more serious cases, symptoms may also include fever, chills, nausea, vomiting, diarrhea, and fatigue.

Healthy Lifestyle Tips

Stress can depress the immune system, thus increasing the body’s susceptibility to infection. Coping effectively with stress is important.1 Exercise increases natural killer cell activity, which may also help prevent infections.2
