There could well be long-term effects of the illness, even for the young.
In most parts of the world, the situation now is worse than it's ever been since this started. We have 3 vaccine candidates that should be here in months. Hold on! Don't give up on being careful now - we could be past this in a few months. If you must meet family or friends for holidays (better if you don't), use masks and ventilation (a few open windows makes a big difference) where possible. If you are unsure about what measures are effective or anything else, please ask and I'll hunt down whatever information you need.
