No surprise that the numbers on positive Covid virus are increasing since testing has substantially increased. Now they even have mobile testing vans show up in small communities offering free Covid tests.
Don't know about other states but Kentucky's voting procedure in this just past primary was only one poling place per county which practically guaranteed more likely to test positive with every voter in a county having to vote at the same facility or else vote by mail.
Past elections each community within a county had their own polling location and depending on population some had more than one.
