DS is 6 and since Friday, has had a mild cough. This afternoon I've noticed he's coughing more. No other symptoms, no temperature, lots of energy and no complaints of illness. Last week he was only at school and home. I'm fine and been wfh for the last week. Is a cough on its own a symptom of coronavirus? Does it take a while for other symptoms to come through? Or is this hopefully just a cough....
