If you do not have symptoms, you should not go testing. There's nothing to test.

If you feel symptoms, but you otherwise feel like you're doing okay and you are not feeling really ill from this, just stay home and stay away from other people.

An at risk person should probably get tested because a positive response would really gonna change what you would do and what the advice that your doctor would give to you.

But, if you are not at risk, and the result is positive, we would not do anything differently than with any other virus like this. Drink fluids, stay home, watch some Netflix.
