Fewer than 10% in the US have antibodies to the novel coronavirus

  • A new nationwide study of the blood of more than 28,000 dialysis patients indicates that approximately 9.3% of people in the US had antibodies to SARS-CoV-2 as of July, as reported by CNN.

  • According to the news source, the numbers ranged from an average of 3.5% in the West to an average of 27% in the Northeast.

  • For the study, which was published in The Lancet, researchers analyzed samples of plasma from more than 28,500 patients receiving dialysis in July at approximately 1300 facilities in 46 states run by one laboratory.

  • The overall percent of people who were positive for antibodies among those sampled was 8%, but as dialysis patients are not representative of the US population, invetsigators standardized the results with respect to age, sex, race and ethnicity and region, to get an estimate of 9.3% seropositivity for the US adult population.

  • They found that there was a wide variation by state, with seven states having 0% seropositivity, to New York, an early pandemic hotspot, topping the list with 33%.

  • "This research clearly confirms that despite high rates of COVID-19 in the US, the number of people with antibodies is still low and we haven't come close to achieving herd immunity," remarked study author Julie Parsonnet.
