Abstract: People across America and the world remain under strong advisories or outright orders to shelter in place, and economies largely shut down, as part of an ongoing effort to flatten the curve of the most virulent pandemic since 1918. The economic effects have been predictably staggering, with no clear end in sight. Until a vaccine or other transformative medical intervention is developed, the broad consensus of experts is that the only way out of mass sheltering in place, if hospital occupancy curves are to remain flattened, entails waiting for most of the current cases to resolve, and then cautiously and incrementally reopening. That would mean a sequence of allowing people out; promptly testing anyone showing symptoms — and even some who are not; identifying recent proximate contacts of those who test positive; and then getting in touch with those contacts and, if circumstances dictate, asking or demanding that they individually shelter until the disease either manifests or not. The idea is to promptly prune branches of further disease transmission in order to keep its reproductive factor non-exponential.
