That being said we know practically nothing actionable about the spread of the disease, little more than we did when it started. Clearly the combination of masks and social distancing has slowed the spread but we don’t know how much good if any the masks really do, and we can’t never go outside again. It’s a waiting game, and a game of seeing just how much isolation we can collectively stomach. Unpleasant, and the end is certainly not yet in sight.
