A tool designed to detect viral history in a drop of blood has gotten an upgrade in the age of COVID-19. VirScan, a technology that can determine which of more than 1,000 different viruses have infected a person, can now also detect evidence of infection from coronaviruses, including SARS-CoV-2.
The researchers also compared the viral histories of hospitalized and non-hospitalized COVID-19 patients and found that hospitalized patients were much more likely to have had CMV and HSV-1, two common herpes viruses.
