In our analysis of seroprevalence of SARS-CoV-2 spike protein receptor binding antibodies from a nationwide representative sample of patients receiving dialysis, we find that despite the USA contemporaneously leading the world in the numbers of diagnosed cases, overall, fewer than 10% of US adults had evidence of seroconversion in July, 2020. ./cache/cord-328865-ekgqdjlk.txt ./txt/cord-328865-ekgqdjlk.txt
