Viral infections are notorious for the symptoms that they cause that affect the respiratory system. That's why coughing is one of the most common symptoms of many viral infections. As the body fights the virus, it may produce a large quantity of phlegm, causing a cough to appear. Coughs may be dry or wet, depending on the amount of phlegm produced.
How are treatments for bacterial and viral infections different?
Answer From Pritish K. Tosh, M.D. As you might think, bacterial infections are caused by bacteria, and viral infections are caused by viruses.
