Obviously I am not a doctor, etc, etc, but I did stay at a Holiday Inn Express last night… Well either that or I read the Chinese report on all of the symptoms/treatments.
Given your location, IMO it’s pretty likely that you do have COVID-19 given your symptoms. If you experience any shortness of breath, I think you should go to the ER immediately. Your age makes it unlikely that you will have a severe case, but it’s not impossible. Depending on your level of concern, you may want to get a pulse oximeter on Amazon shipped to you ($15-20) and keep an eye on it. If your blood O2 gets down below 93%, it’s time to go to the hospital based on the findings in China.
