Five ways we know that the American response to the coronavirus isn’t yet working.

1) There is still no sign of the curve flattening. Daily deaths in the United States have exceeded 1,000, and total deaths are now about 6,000. The number of new confirmed cases per day has exceeded 30,000, also a new high.

2) The caseload is growing more rapidly here than in Europe. In the chart above, I’ve compared the pace of growth in both the United States and a section of western Europe with a nearly identical combined population. (The European region includes 16 adjacent countries, all on the Continent; the full list is below.) The outbreak began earlier in Europe, so it still has a higher caseload. But the United States is on pace to overtake it.

3) The shortage of medical supplies continues. Doctors, nurses and other health care workers are having to take terrible risks, as a result. “Everyone is scared. Patients are scared. Staff is scared,” Erika Sawyer, a nurse-midwife, told The Times Magazine. “All masks are being rationed, and we don’t know how many we have.”
