There seem to be some pretty solid numbers on how long coronavirus will last on a given surface. But I’m curious what the curve looks like. Does it decay at a constant rate, like a radioactive substance? Or does it behave more like a group of animals denied food, where the population survives relatively intact for a while before hitting a point of rapid decay? I’m trying to evaluate the effectiveness of leaving things to sit for e.g. 24h if I can’t disinfect them and can’t wait the full recommended time.
