Geographic distribution of undiagnosed seropositivity in the United States from May to July 2020. Raw serology data for (A) IgG, (B) IgM, and (C) IgA against SARS-CoV-2 spike protein and the receptor binding domain (RBD) of spike protein are displayed. Cut points for positivity are shown as red dashed lines; data are optical density (OD). (D) Serologic phenotype of antibody presence in 304 seropositive participants. (E) The map of the United States displays seropositivity in the six regions surveyed: Northeast: ME, NH, VT, MA, NY, CT, RI, PA, and NJ, 7.5% (95% CI, 3.9% to 12.4%); Midwest: MN, IA, WI, IL, IN, MI, and OH, 1.6% (95% CI, 0.3% to 2.4%); Mid-Atlantic: MD, DE, DC, VA, WV, KY, TN, NC, SC, and GA, 8.6% (95% CI, 2.6% to 18.9%); South/Central: FL, MS, AL, LA, AR, MO, KS, and OK, 3.0% (95% CI, 1.2% to 5.0%); Mountain/Southwest: TX, NM, AZ, CO, UT, WY, NE, SD, ND, MT, and ID, 4.5% (95% CI, 1.3% to 9.5%); West/Pacific: WA, OR, NV, CA, AK, and HI, 1.9% (95% CI, 0.2% to 3.8%). Each person in (E) represents 100 participants; orange represents weighted prevalence estimate within the geographic region.

When the coronavirus pandemic began, health officials said it caused a new infection that we knew very little about.

So a team of researchers at the National Institutes of Health started a clinical study to find out how prevalent COVID-19 was all over the United States.

Michelle O'Neill reports the peer-reviewed study found there were four to five times more undiagnosed cases of COVID-19 for every known case.

Lead Investigator, Dr. Matt Memoli, and his team worked with two universities to conduct the study entitled, "Undiagnosed SARS-CoV-2 Seropositivity During the First Six Months of the COVID-19 Pandemic in the United States."

The clinical study is online published by "Science Translational Medicine."
