What do you think is the ethical option? If you are positive shouldn't the people in contact with you know it? I'm genuinely asking, it's not a rethorical question. I think they should know they have been exposed to the virus at least, not necessarily knowing it was you. You already have lost some rights of movement and assembly. Losing some privacy may help you regain them sooner.
