I have a sore throat, dry cough, and mild fever. Four days since the onset of the first, very mild symptoms (tingling in the throat).
This is an example of how the virus spreads so easily, not that you have it.
You might have only have a common cold. Problem is what do you do because you don't know for sure. You assess your risk and pretest probability. There are already cases in Florida. If you know you have been exposed to one, you should get tested and avoid contact with others. If you can't get tested then you should self quarantine for 14 days. But I don't want to miss work for nothing! A valid point, but if you are infected you are already spreading the virus. Honestly I think we are beyond the point when we can do individual isolation to who has been exposed to known individuals, particularly because you are infectious when you are still asymptomatic. If your work is not essential or even better, can be done for home, you should do so.
What I mentioned about testing is probably not feasible because you are probably a lower risk unless you were in contact with people traveling from Europe recently and we don't have enough testing.
If you get sicker than you should go to the hospital.
