Gosh, sorry to hear you are not feeling well!!! And I completely understand that right now, all illnesses are scary. They do have a pretty good chart out right now of how to tell symptoms apart. One thing that I have noticed on all of the charts is that runny noses, stuffed noses, etc. are more indicative of a cold. There are upper respiratory infections and lower respiratory infections. Colds are upper and Corona virus is lower. The hallmarks of the corona virus are dry cough, fever and shortness of breath. I do read a lot that people also may start with a sore throat. But sneezing and a lot of nose activity is more of a cold symptom. Regardless, your symptoms would be mild if you have the virus and we are all supposed to act like we have it and stay away from others. So, do that if you can. :>) Here's that chart on symptoms. https://www.health.gov.au/sites/default/files/documents/2020/03/coronavirus-covid-19-identifying-the-symptoms.pdf
