New York City health officials estimate that nearly a quarter of adult New Yorkers were infected with the coronavirus during the catastrophic wave of last spring, and that the toll was even higher among Black and Hispanic residents.
The estimates, based on antibody test results for more than 45,000 city residents last year, suggest that Black and Hispanic New Yorkers were twice as likely as white New Yorkers to have had antibodies to the coronavirus — evidence of prior infection.
Hispanic New Yorkers had the highest rate, with about 35 percent testing positive for antibodies, according to the study, whose authors include officials and researchers at the city Health Department and the National Institute for Occupational Safety and Health. Among Black New Yorkers, 33.5 percent had antibodies. Among Asian New Yorkers, the rate was about 20 percent. For white New Yorkers, the rate was 16 percent.
Antibody surveys of segments of the population have become a useful way to gauge what percentage of people were infected and what groups were most at risk, especially since there was limited testing for the virus during the first wave.
The new paper, which has been accepted by the Journal of Infectious Diseases, has substantial limitations: Of the 45,000 New Yorkers in the study, fewer than 3,500 were Black, a major underrepresentation. And the participants were recruited partly through advertisements online, which the study’s authors acknowledge may have attracted people who believed they had been exposed to Covid-19.
But the study adds to experts’ understanding of the disproportionate toll that the pandemic has taken on Black and Latino people.
Its findings also come amid a push to vaccinate more people in the United States. A recent survey conducted by the Kaiser Family Foundation found that the number of Americans, particularly Black adults, who want to get vaccinated has continued to increase. According to an analysis last month by The New York Times, Black people were still being inoculated at half the rate of white people. The disparities are especially alarming as Black and Latino people and Native Americans have been dying at twice the rate of white people.
In New York City, about 44 percent of white adults have received at least one dose of a Covid-19 vaccine, while 26 percent of Black adults and 31 percent of Latino adults have, according to city data.
Experts and community leaders across the country say that over all, the lower vaccination rates are linked to technological and linguistic barriers and disparities in access to vaccination sites. Other factors include social media misinformation and a hesitancy to be vaccinated. Hesitancy among African-Americans, experts say, can be tied to a longstanding mistrust of medical institutions that have long mistreated Black people.
have comparatively fewer white workers.
“These were the people who did not have the luxury of being able to work virtually,” she said.
Dr. Kitaw Demissie, who is dean of the School of Public Health at SUNY Downstate Medical Center in Brooklyn and was not involved in the study, noted that household crowding may have also contributed to differing infection rates. Some predominately Latino neighborhoods which were particularly hard hit in the first wave had high rates of household crowding.
More than 32,000 people in New York City have died from Covid-19 in total, according to a New York Times database.
