What were some symptoms of the plague?

 It took awhile for the symptoms of the plague to show up. Some simple signs would be nausea and headaches. Once the plague has fully set in then you start to get black, boil-like bumos on your body. The first one normally appears on your armpit. The boils soon cover-up most of your body.

 Another symptom of the plague would be blue or black blotches on the skin; something like rashes. If a person started to notice these symptoms on their body they were  required to see a doctor for immediate medicines and tests. The docotors do all they can, and pretty soon the person dies within 48 hours (2 days).
