I have two teens at home with COVID.
Teen 1 is having a dreadful time; headache, cough, sore throat, aching, exhaustion.
Teen 2 has absolutely no symptoms.
(interestingly Teen 1 has a very faint positive while Teen 2 has an immediate thick dark positive line, anyway...)
Both teens have heavy sport schedules playing for school and club teams. 8 or 9 hours a week training and matches is usual, plus gym and fairly physical sport-related part time jobs. I am concerned about doing too much too soon and have told Teen 1 that she will be taking it very slow and will not be back to full sport for a couple of weeks at least.
What about Teen 2? If he is completely a-symptomatic does he still need to rest? Take it slow? Is his immune system still taking a battering? Can he go straight back to practice?
