<human>: My college classmates and I are becoming increasingly agitated over a fellow colleague's pungent body odor. I know this sounds immature and shallow, but the smell is distracting and nauseating, to the point I have to hold my breath. We are healthcare students and have strict regulations as it is regarding hygiene, b.o. and cigarette smoke ect, so the patients are being exposed to this as well. 

I would like to give this person the benefit of the doubt, perhaps it's the result of a medical condition, but it doesn't outweigh the fact that there is no apparent attempt on their part to mask the odor. If I had to describe it, I would say it smells like this person never showers, is wearing dirty clothes and underwear, sour dish towel, and a mix of armpit b.o. and layers of pungent dried bodily secretions. Normally this wouldn't bother me, however this person is constantly in my close vicinity and I can literally taste it in my mouth. It's starting to really irritate me and violate my personal space.

Other people have made comments but not directly toward her, just in front of her, they also reported her to instructors and apparently she was talked to....but se continues to come to class and clinical with the same overwhelming odor. 

Should someone say something directly to her? I've researched body odors and truly cannot attribute it to anything that fits the description, but regardless I don't want to offend a potential disorder. Do I have the right to be assertive about my personal space or should I suck it up and just avoid her as much as possible (hard)? Please help!

Can you condense the text into a few key points?
<bot>: Classmate smells extremely putrid, hard to tell why, it's beginning to nauseate me and I have to work within close proximity to her. To address it or not?
