As you likely know by now, the presence of COVID antibodies indicates people who have had COVID (knowingly, or completely asymptomatically). The DOHMH for NYC has released a map of COVID antibody testing. Our (East Harlem) data is based on 6,258 tests:
The city on Tuesday released the results for roughly 1.5 million coronavirus antibody tests conducted since mid-April. The new data confirms earlier reports that the virus has hit people of color and low-income communities harder than more well-off neighborhoods in New York City. At 33 percent, the Bronx saw the highest rate of people who tested positive for COVID-19; in Manhattan, 19 percent of antibody tests were positive. A new map and table released by the city’s health department break down antibody testing rates by ZIP code, age, borough, sex, and neighborhood poverty.
As you can see, our community is somewhere in the middle of Manhattan’s range. Many more people in Washington Heights have had COVID, and many people south of is in the upper East Side, for example, have not had COVID.
The lowest rates in Manhattan, which had the lowest overall rate of positive antibodies, were found on the Upper East Side and Upper West, both at 12.6 percent positive. No neighborhoods south of Harlem saw rates higher than 20 percent. In the ZIP code 10036, which includes Midtown West, 19.6 percent of those tested had antibodies.
Some researchers say those with COVID antibodies are likely protected from getting the virus again or as severely, possibly offering some relief to those neighborhoods hardest hit early on in the crisis. But there are still too many unknowns, and the city wants everyone, antibodies or not, to consider themselves at risk for infection.
