Yes, the coronavirus curves are plateauing. There are fewer hospital admissions in New York, the center of the epidemic, and fewer Covid-19 patients in I.C.U.s. The daily death toll is still grim, but no longer rising.

The epidemiological model often cited by the White House, which was produced by the University of Washington’s Institute for Health Metrics and Evaluation, originally predicted 100,000 to 240,000 deaths by midsummer. Now that figure is 60,000.

While this is encouraging news, it masks some significant concerns. The institute’s projection runs through Aug. 4, describing only the first wave of this epidemic. Without a vaccine, the virus is expected to circulate for years, and the death tally will rise over time.
