What are the two differences between how we treat bacterial disease and how we treat viral disease

A bacterial disease is caused mainly by bacteria or bacterial components and is highly contagious. Disease happens mostly when the abnormal number of bacteria present on the body exceeds its threshold. On the other hand, a viral disease occurs when one’s body is invaded by pathogenic viruses that normally attacks susceptible cells (common when one’s immune system is weak). Since they originated from two different sources, the treatment is very different. For bacterial diseases, it is being treated by using antibiotics specific for the bacteria present in the body. However, for a viral disease, antibiotics will have no effect on viruses, hence, antiviral drugs have been developed.
