More cases of COVID-19 are likely to be identified in the coming  days, including more cases in the United States. It’s also likely that  sustained person-to-person spread will continue to occur, including  throughout communities in the United States. It’s likely that at some  point, widespread transmission of COVID-19 in the United States will  occur.
Widespread transmission of COVID-19 would translate into large  numbers of people needing medical care at the same time. Schools,  childcare centers, and workplaces, may experience more absenteeism. Mass  gatherings may be sparsely attended or postponed. Public health and  healthcare systems may become overloaded, with elevated rates of  hospitalizations and deaths. Other critical infrastructure, such as law  enforcement, emergency medical services, and sectors of the  transportation industry may also be affected. Healthcare providers and  hospitals may be overwhelmed. At this time, there is no vaccine to  protect against COVID-19 and no medications approved to treat it. Nonpharmaceutical interventions would be the most important response strategy.
