Just over one-third of people tested for antibodies in the Bronx district of New York City returned positive, according to data from the city’s health department released Tuesday.
At 33.1 percent, the Bronx has the highest percent positive rate of antibody testing among the city’s five districts. This number represents the proportion of antibody tests that were performed and returned positive.
Queens and Brooklyn fell in second and third place, respectively, at 28.2 and 27.9 percent positive rates. Manhattan and Staten Island had a positivity rate of about 20 percent.
In one Queens Postcode, more than 50 percent of the people who received tests were found to have antibodies, while no zip code in the lower half of Manhattan had a positivity score higher than 20 percent.
The Bronx was also the least tested neighborhood, with about 15,000 antibody tests performed for every 100,000 people compared to 23,685 in Manhattan.
Unlike most of the data related to cases and deaths of coronavirus, data on antibody tests are not broken down by race because most labs do not collect that information, the health department said. However, the antibody data underline the racial and wealth differences in the pandemic.
The data also found that people living in “very poor” neighborhoods had a positivity rate of 35 percent, compared to an 18.5 percent positive degree in the “low poverty” category.
The Centers for Disease Control and Prevention has listed poverty and subsequent surpluses as a risk factor in the coronavirus pandemic.
