At a clinic in Corona, a working-class neighborhood in Queens, greater than 68 p.c of individuals have examined constructive for antibodies to the virus, suggesting that their immune programs had encountered an an infection and responded to it. At a clinic in Jackson Heights, additionally in Queens, that quantity was 56 p.c. However at a clinic in Cobble Hill, an prosperous Brooklyn neighborhood, solely 13 p.c of individuals examined constructive for antibodies.
Whereas stopping wanting 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 stated that the completely different ranges of antibody prevalence have been more likely to play a task in what occurs subsequent, assuming that antibodies do, in reality, supply vital safety towards future infections.
“Some communities may need herd immunity,” stated 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.
Because the virus has swept via New York, it has uncovered stark inequalities in practically each facet of metropolis life, from who has been most affected to how the health care system tended to those patients.

But when there’s a second wave of the virus, a few of these vulnerabilities could flip, with the prosperous neighborhoods turning into most in danger for a surge of infections.
The CityMD statistics mirror exams executed from late April to late June. As of June 26, CityMD had administered about 314,000 antibody exams within the metropolis; citywide, 26 p.c of the exams got here again constructive.
The testing leads to Jackson Heights and Corona appeared to “soar off the map,” Dr. Frogel stated.
