As much as I find questions about symptoms
to be a complete waste of time
and an unnecessary source of anxiety for MedHelp clients, you have approached the issue from a slightly different perspective which is worthy of comment. That is, could ARS symptoms be mistaken for something else. The answer is yes. The symptoms or the ARS are those of a severe, flu-like illness of the sort that most people get every so often. Fevers, muscle and joint aches, and rash are all part of the syndrome.
