She was previously healthy, very involved in campus politics, and a 4.0 student. About 2 weeks ago, she started not feeling well. She had bad nasal congestion, and was diagnosed with a sinus infection. However, she decided against taking antibiotics because she did not believe they were good for her. She started getting very high fevers, which Amanda told her roommate were good because they were killing the infection. Yesterday, she started complaining of a stiff neck, and today she seems especially lethargic with a fever of 105. Her roommate was scared, so she forced her into her car and has driven her to your ICU.
