Would you go to work if you had a bad upper respiratory infection?

Bad URI: Depends on whether you have a fever or how badly you feel. If there is fever, it is best to stay home and rest while you take lots of fluids and comfort yourself with aspirin. If you have body aches, cannot breathe because of nasal stuffiness, have frequent cough, feel fatigued - all without fever, it is best to rest as well and follow the previous recommendation. A workaholic may not agree!

Yes and no: I'd work if a) i felt O.K., b) my performance was not critical, c) i was hygienic enough to prevent contagion, and d) others were available to cover my duties.
