As this general medical term indicates, a bacterial infection is caused by bad bacteria in the body. The standard medical treatment usually involves a dose of antibiotics. Bacterial infections are easily confused with the viral infections, which, as you will again clearly see from their name, have viral causes. These two types of infections share similar symptoms, so it is impossible for an ordinary person to tell them apart. Only a trained doctor can determine if an infection is bacterial or viral. They have to be skilled in distinguishing between bacterial and viral infections because only the former responds to antibiotics.
If an infection continues for more than a few weeks, it is appropriate to get checked by the doctor to see if it is a bacterial infection. Usually, viral infections do not continue for much longer than a couple of weeks. To make the diagnosis even more complicated sometimes what begins as a viral infection goes on to develop into a bacterial infection. If you have even the slightest doubt, consult your doctor. Through blood tests and cultures, doctors can diagnose which kind of infection the patient has developed.
