The testing outcomes from the urgent-care firm CityMD have been shared with The New York Times.
At a clinic in Corona, a working-class neighborhood in Queens, greater than 68 p.c of individuals have examined optimistic for antibodies to the virus, suggesting that their immune techniques had encountered an an infection and responded to it. At a clinic in Jackson Heights, additionally in Queens, that quantity was 56 p.c. But at a clinic in Cobble Hill, an prosperous Brooklyn neighborhood, solely 13 p.c of individuals examined optimistic for antibodies.
While stopping in need of predicting that hard-hit neighborhoods like Corona and Jackson Heights can be comparatively protected in any main new outbreak — a phenomenon known as herd immunity — a number of epidemiologists mentioned that the completely different ranges of antibody prevalence have been more likely to play a job in what occurs subsequent, assuming that antibodies do, actually, supply important safety towards future infections.
“Some communities might have herd immunity,” mentioned Dr. Daniel Frogel, a senior vp for operations at CityMD, which runs urgent-care facilities all through the metropolitan space and performs a significant position within the metropolis’s testing program.
As the virus has swept by way of New York, it has uncovered stark inequalities in practically each side of metropolis life, from who has been most affected to how the health care system tended to those patients. Many lower-income neighborhoods, the place Black and Latino residents make up a big a part of the inhabitants, have been hard-hit, whereas many rich neighborhoods had far fewer circumstances.
But if there’s a second wave of the virus, a few of these vulnerabilities might flip, with the prosperous neighborhoods changing into most in danger for a surge of infections.
The CityMD statistics mirror assessments carried out from late April to late June. As of June 26, CityMD had administered about 314,000 antibody assessments within the metropolis; citywide, 26 p.c of the assessments got here again optimistic.
The testing ends in Jackson Heights and Corona appeared to “jump off the map,” Dr. Frogel mentioned.
