If present, would ARS symptoms come all at once or one by one, for example, one day have a sore/burning/itchy or scratchy throat, a day later develop nasal congestion or runny nose, and
maybe at the third day develope a dry
or productive cough
, lasting only the cough. Woudl this be a typical onset of ARS symptoms or not? Or would they all come at once, like, hit you at the same time?
