Before revision:  The combination of social isolation and PPE resulted in very low levels of infection. Our model suggests that widespread application of social distancing through government control can drastically reduce viral spread; even in the absence of widely adopted social distancing protocols, high use of PPE can also dramatically reduce the viral spread while short-duration quarantine following exposure to an infected individual was less effective .
After revision:  For each of these control measures, the total number of infections exhibits a sharp phase transition as the strength of the measure is varied .
