The results of tests by the emergency care company CityMD were shared with the New York Times.
In a clinic in Corona, a working-class neighborhood in Queens, more than 68 percent of people tested positive for antibodies to the virus, suggesting that their immune system had encountered and responded to an infection. In a clinic in Jackson Heights, also in Queens, that number was 56%. But in a clinic in Cobble Hill, a well-to-do neighborhood in Brooklyn, only 13% of people tested positive for antibodies.
While not anticipating that hard-hit neighborhoods like Corona and Jackson Heights would be relatively protected in any new major outbreak – a phenomenon known as collective immunity – several epidemiologists have said that different levels of antibody prevalence are likely to playing a role in this then occurs, assuming that the antibodies do, in fact, provide significant protection against future infections.
“Some communities could benefit from collective immunity,” said Dr. Daniel Frogel, senior vice-president of operations for CityMD, which operates emergency care centers throughout the metropolitan area and plays a vital role in the program. city screening.
As the virus invaded New York, it exposed glaring inequalities in almost every aspect of city life, which was most affected by the way the health care system tended to these patients. Many low-income neighborhoods, where black and Latino residents make up a large part of the population, were hit hard, while many wealthy neighborhoods had far fewer cases.
But if there is a second wave of viruses, some of these vulnerabilities can be reversed, affluent neighborhoods being the most exposed to an outbreak of infections.
CityMD statistics reflect tests carried out from the end of April to the end of June. As of June 26, CityMD had administered approximately 314,000 antibody tests in the city; across the city, 26% of tests returned positive.
The test results at Jackson Heights and Corona seemed to “jump off the map,” said Dr. Frogel.
