A 28-year-old female anthropology graduate student returns from her trip to Brazil, where she spent the summer in the Amazon rainforest.  During her trip she suffered multiple bug bites and after four days had stopped using her bed net because it was too hot and she was getting bit so much in the daytime anyway.   About a week after her return she wakes up at night with chills, sweating with fever.  She assumes she picked up a virus during her travels and takes Tylenol to get though the night.  The next day she is feeling better, but a days later the symptoms recur.   She schedules an appointment with her physician.  He requests urine and blood samples.  As she places the specimen cup with urine in the wall cabinet to the lab, she notices her urine is very dark.
