That sounds about right for the data set they are talking about - onset to mid May. NY state took the brunt of the initial infection - death rates there will be higher than anywhere else. Right now, based on antibody testing from almost 2 months ago, I'd say NY state death rate is around 1%, but it will continue to drop. We need updated serology data to see where NY state is right now. I read one report today of a clinic in NYC finding 68% of patients testing positive for antibodies!
If NY state is really at 25% infection rate, the death rate drops to 0.5%
That may have been the NYT article regarding the testing results in Jackson Heights and Corona (!) CityMD locations.

"At a clinic in Corona, a working-class neighborhood in Queens, more than 68 percent of people tested positive for antibodies to the new coronavirus. At another clinic in Jackson Heights, Queens, that number was 56 percent. But at a clinic in Cobble Hill, a mostly white and wealthy neighborhood in Brooklyn, only 13 percent of people tested positive for antibodies.
As it has swept through New York, the coronavirus has exposed stark inequalities in nearly every aspect of city life, from who has been most affected to
how the health care system cared for those patients. Many lower-income neighborhoods, where Black and Latino residents make up a large part of the population, were hard hit, while many wealthy neighborhoods suffered much less.
But now, as the city braces for a possible second wave of the virus, some of those vulnerabilities may flip, with the affluent neighborhoods becoming most at risk of a surge. According to antibody test results from CityMD that were shared with The New York Times, some neighborhoods were so exposed to the virus during the peak of the epidemic in March and April that they might have some protection during a second wave.
“Some communities might have herd immunity,” said Dr. Daniel Frogel, a senior vice president for operations at CityMD, which plays a key role in the city’s testing program.
The CityMD statistics — which Dr. Frogel provided during an interview and which reflect tests done between late April and late June — appear to present the starkest picture yet of how infection rates have diverged across neighborhoods in the city.
As of June 26, CityMD had administered about 314,000 antibody tests in New York City. Citywide, 26 percent of the tests came back positive.
But Dr. Frogel said the testing results in Jackson Heights and Corona seemed to “jump off the map.”
While stopping short of predicting that those neighborhoods would be protected against a major new outbreak of the virus — a
phenomenon known as herd immunity — several epidemiologists said that the different levels of antibody prevalence across the city are likely to play a role in what happens next, assuming that antibodies do in fact offer significant protection against future infection.
“In the future, the infection rate should really be lower in minority communities,” said Kitaw Demissie, an epidemiologist and the dean of the School of Public Health at SUNY Downstate Medical Center in Brooklyn.
Dr. Ted Long, the executive director of the city’s contact-tracing program, said that while much remained unknown about the strength and duration of the protection that antibodies offer, he was hopeful that hard-hit communities like Corona would have some degree of protection because of their high rate of positive tests. “We hope that that will confer greater herd immunity,” he said.
Neighborhoods that had relatively low infection rates — and where few residents have antibodies — are especially vulnerable going forward. There could be some degree of “catch up” among neighborhoods, said Prof. Denis Nash, an epidemiology professor at the CUNY School of Public Health.
But he added that even if infection rate were to climb in wealthier neighborhoods, “there are advantages to being in the neighborhoods that are hit later.” For one, doctors have become somewhat more adept at treating severe cases."
It goes on quite a bit more.
