I believe it is a mistake for health departments to put privacy above serious health risks.
The identities of the persons who contract the novel coronavirus Covid-19 should be shared with the public in those particular areas, unless the person specifically asks that it not be.
In this pandemic situation, the well-being of other human beings should be considered above any privacy issues.
If I or a family member had the virus, I would be the first to get on the phone and contact everyone I had been close to.
This is not a secret to keep. There is no stigma. We should be trying to protect others.
