What do you think is the most likely cause of sue's illness? provide evidence to support your theory?

I’m not sure if this question is asking what illness I think she has or what factors caused her to get the illness, so I will answer both. 1) I figure strep throat because they are in an area that shouldn’t have any huge deadly diseases, it is easy to spread, and the symptoms display the illness perfectly. 2) I think that Sue’s bad lifestyle habits have been affecting her immune system. Taking in so much caffeine is awful for the body and pulling "all nighters" paired with physical exertion from sports reduces the efficiency of her immune system, leaving me to believe she caught this from her friend from another college.
