This makes me wonder about an incident we had. My husband had Covid and didn’t know it, a few days later I got sick and tested positive. 3 days later the contact tracer called my cell and one of the questions was “who had I been in contact with”. I said my husband and she wanted to speak to him; since he was 3 ft from me I went to hand him my cell but the contact tracer said no, she had to call him on his own cell. It made no sense as to the reasoning but now makes me wonder if it is related to this.
Great post. I leave my phone at home unless I am working.
