Editor's Note In this study, researchers from the Icahn School of Medicine at Mount Sinai, New York City, find that most COVID-19 patients have persistent antibodies to the SARS-CoV-2 virus for more than a year after acute infection. The study also shows that patients with more severe disease had higher…

Editor's Note In this study, researchers from Stanford University School of Medicine found that some COVID-19 patients experience milder symptoms than others because they have more CD8+ T cells (killer T cells) that remember previous encounters with seasonal coronaviruses. The researchers first confirmed that some portions of the SARS-CoV-2’s sequence…

Does it really matter if surgical instruments are submerged in cleaning solution when technologists or nurses scrub them after a case? Is there a reason for the 3-foot separation between dirty and clean areas? Do germs stop at the red line? During the COVID-19 pandemic, much attention has been focused…

Editor's Note Researchers from 17 healthcare organizations report that COVID-19 hospitalizations and death can be reduced with early outpatient treatments. The researchers designed an algorithm comprising treatments in order of disease severity: Immediately give zinc lozenges 5 times per day or zinc sulphate 220 mg every day for 5 days.…

Editor's Note This study by researchers at La Jolla Institute for Immunology, La Jolla, California, finds that T cells fight SARS-CoV-2 by targeting a broad range of sites on the virus, beyond the key sites on the spike protein. By attacking the virus from many angles, the T cells can…

Editor's Note This large US study of patients who contracted COVID-19 confirms and provides risk estimates for numerous complications of the disease. Using US health claims data of 70,288 patients who had a COVID-19-related healthcare visit between March 1 and April 30, 2020, researchers found that 53.4% were admitted to…
