Viral Infections
Description
Viruses are capsules with genetic material inside, and are much smaller than bacteria. They enter cells of the body and use the cells to produce more viruses eventually killing the cells. The cell death and the body’s immune response to fight the virus cause the symptoms experienced. Viruses cause a whole host of diseases that range from the common cold and flu to AIDS and hemorrhagic fever. Viral infections are hard to treat and they do not respond to antibiotics. There are only a few anti-viral medications available. Vaccines can prevent some viral infections.
Symptoms
Symptoms vary depending on the virus causing the infection. In general they cause: fever, muscle aches, fatigue.
Tests
A history and physical exam will be performed. Additional tests will be done to establish the diagnosis.
Treatment
Treatment depends on the virus causing the infection. Many times the only therapy available is to treat the symptoms since there are not many anti-viral medications available. Viruses do not respond to antibiotics.
