These diseases were caused by bacteria, viruses, and microorganisms. So through fleas, or even just breathing the contaminated air. The doctors had no tools to see deep inside the body and no tests. So the doctors would have to go through alot just to find out what the disease is, when today with all of our tools we could know right away. If the patients were males, the doctors examined them, but if it was a female the doctors listened to the verbal descriptions of the patients sufferings to see what there diagnose is. Also, the doctors looked at the patients breathing, pulse, and heartbeat. The body was said to have 4 body humors: phlegm, yellow bile, blood, and black bile. If you were ill, the humors were out of balance.
Any disease you had could be cured by food, rest, exercise, massage, accurate physical therapy, or of course medicines. This is everything we would use today. The only thing that is different is we had tools and tests to examine the disease right away so the patient can get treated.
