yes, adults get this. i know i have had it three times and it can be brutal. the first time is the worst. it can have lasting affects also. i still have joint pain as it can settle in the joints. never have been the same since. the problem is that doc. don't know much about this disease and can't really help much. i have found out more just doing research myself. it will pass, but what i have read can take anywhere from 2 to 4 years to be symptom free. (If you don't get it again) my advice, keep exercising, do research and talk with others. What I have been looking at is if it will go into other forms of diseases like Lupus. only time will tell.
