I already tried using all my resources.

1. why is cholera so stressful on the body?
2. what part of the digestive tract is most susceptible and why?
3. why is the upper respiratory tract a good place for bacteria to grow?
4. what is a symptom of diphtheria and why is it life threatening?
5. why is it rare for people in the U.S to get diptheria or pertussis?

thank you!
