viral infection

viral infection An infection caused by the presence of a virus in the body. Depending on the virus and the person’s state of health, various viruses can infect almost any type of body tissue, from the brain to the skin. Viral infections cannot be treated with antibiotics; in fact, in some cases the use of antibiotics makes a viral infection worse. The vast majority of human viral infections can be effectively fought by the body’s own immune system, with help from proper diet, hydration, and rest. Treatment of other viral infections depends on the type and location of the virus and may include use of antiviral or other drugs.
