New Case:
I first learned about this case from a colleague at work who tells me that their friend has just gotten really sick. The friend is described as having had multiple illnesses over time but that he has never been as sick as he recently got. He reports that the illness began as a diffuse myalgia with fever, there was some sore throat, noted swelling in the neck, and overwhelming fatigue. He tells some of his friends that he is feeling really terrible and it turns out that some of his friends also feel poorly. It turns out that about a week prior to the onset of his symptoms he and a number of friends attended a large dinner where venison and boar was served. 
This individual is then seen in our office. Some testing is done. He feels really terrible and despite being reassured that he should get better without treatment he is given therapy.

New Case study:
I was recently asked about this case while I was off visiting Denmark. A man in his 50s has been reporting months of abdominal discomfort and decides to go discuss this situation with a local pharmacist. He describes this discomfort, some nausea, and some bloating of the abdomen. The pharmacist recommends that he take mebendazole. He takes the mebendazole and some time afterwards he vomits a worm into the sink. The worm does not have any obvious segmentation and appears completely nonsegmented and is moving around. One end is very pointy and the other little less so.

New Case study:
A physician with no significant PMH who is currently doing their fellowship training develops diarrhea. The diarrhea is significant enough that they are beginning to feel weak, lightheaded, and end up going to the local ER. The physician lives in NYC, works most of the time but did just get back from a week-long vacation in Florida with their long-term partner where they got a chance to swim in the pool and get some sun. They returned feeling well and then noted the onset of the diarrhea. The diarrhea was watery, with some abdominal cramping but no noted blood or actual fever. The stool did not have a strong smell and no floating stools were reported. The physician was given IVF and returned home feeling better but now gets a call that there is a parasite on the stool testing and is recommended to take a medicine they have never heard of 3x per day for 3 days.
