Given that most forms of social distancing will be useless if sick people cannot get treated—or afford to stay away from work when they are sick—the federal government should also take some additional steps to improve public health. It should take on the costs of medical treatment for the coronavirus, grant paid sick leave to stricken workers, promise not to deport undocumented immigrants who seek medical help, and invest in a rapid expansion of ICU facilities.

The past days suggest that this administration is unlikely to do these things well or quickly (although the administration signaled on Monday that it will seek relief for hourly workers, among other measures). Hence, the responsibility for social distancing now falls on decision makers at every level of society.
