Quoting
Mr. Knowitall
Depending on the nature of the illness, your job and job duties, the term of your employment and the number of employees your employer has in the vicinity, you may be able to seek accommodation under the ADA to limit or end company travel - if you are inclined to pursue that sort of remedy. That's not the question you asked, so I'll leave it at that for now.
Depending also on the nature of your illness and whether travel contributes to episodes or flare-ups, you may be able to get care through worker's compensation. From the little bit you've shared so far it doesn't sound like that would follow from your illness, but we don't have the details.
