Nurse Kate Heals Mitchieville

So, Mitchievillians, it seems you fancy yourself quite the smarty-britches. However, I must note that in your broad experience from guessing the nerds of the animals kingdom to spotting uncannily attractive transvestites your record has been spotty. Hence, I bring you a bona-fide challenge designed to tickle your cerebellum without causing any "cognitive dissonance". I bring you: What The Hell Do I Have?

Guess what this person has based on the case studies below. The ones for this round are all infectious diseases and unrelated in terms of endemic environment and severity.

1) Fenris went down to visit his cousins in New Mexico. While he enjoyed his stay in the trailer park, he complained that the constant rains kept him indoors a lot and the mice disturbed his sleep. He got back a few days ago, and has developed what at first seemed to be a cold, but has now rapidly become a very serious pneumonia. On auscultation, his lungs sound very "wet". What does he have?

2) The Mayor has just completed a tour of Africa's most charming villages. While on his trip, he enjoyed spelunking and exploring the wilderness. Upon is arrival home, he complains of intense joint pain and is extremely fatigued. You notice that he has developed a petechial rash on his extremities. What does he have?

3) Lisa, 38 years old, comes into the emergency ward with extreme pain in her ear. She thought she had an ear infection and was prescribed antibiotics, but they haven't helped. Now there are red welts on her affected ear and some of the skin is sloughing off. Every time she hears a loud noise it causes her to vomit violently. What does she have?

4) Steamboat McGoo comes into your clinic very upset about a skin infection. He nicked the back of his hand yesterday, and the tiny cut has become inexplicably painful. On inspection, the site is red, swollen, and extremely painful to the touch. The redness extends about 2inches from the 1/4 inch cut. He says the redness spread very quickly from this morning and he is feeling sick and weak. On examination, he is running a high temperature. What does he have?
