Earlier quoted context omitted.
Are there any data on the severity of the symptoms? From what I've gathered, but without any hard data, in non-severe cases (i.e. not needing hospitalization) they can vary from a slight sore throat, dry cough and mild fever, to the same with a high fever and general sense of exhaustion.
Non-severe covers bronchitis, pneumonia, etc. My friend (who tested positive but was not hospitalized) described it as "chest pain, difficulty breathing, if I do something silly like walk 10 feet to the kitchen I get lightheaded and hold on to the wall" - for about ten days.
I see this all the time, on a site that used to be a really good spot for rational discussion.
