The United States is more than eight months into the pandemic and people are back waiting in long lines to be tested as coronavirus infections surge again. And yet there is still no federal standard to ensure testing results are being uniformly reported. Without uniform results, it is impossible to track cases accurately or respond effectively.

As states struggle to contain the resurgent coronavirus, many officials are laying the blame on an unexpected source: people gathering with family and friends.

Household get-togethers undoubtedly do contribute to community transmission of the virus. Canada’s recent Thanksgiving certainly added to its rising cases; such an increase may happen here, too, as the United States embarks on a holiday season like no other. That’s why the Centers for Disease Control and Prevention on Thursday warned so strongly against gathering with others outside the household during Thanksgiving.
