If you’re in the United States, where testing has been infuriatingly limited, the fact of the matter is you have no idea what the spread in your community is. The numbers aren’t low because nobody has the virus, they’re low because nobody has been tested. If we did actual testing, they might come in low or they might come in high, who knows. As it stands, nobody has any real idea just how bad the spread is here. Absence of evidence is not evidence of absence.

Given that, the safest course is to assume the spread is high, and act accordingly.
