I like the perspective of this quote:
“If we had fast, highly accurate, and inexpensive home testing, we could repeatedly test ourselves before going to work, heading off to school, or otherwise spending time near others. If the tests were more accurate, we could more confidently rely on testing to know when it’s safe to relax distancing, masking, and other protective measures. But we aren’t there yet.”
