Editor's Note This study by researchers at Brown University, Providence, Rhode Island, reveals the cellular mechanism behind why the elderly and patients with preexisting conditions are at higher risk of infection, severe side effects, and death from COVID-19. The researchers detail their discovery that circulating levels of a protein called…

Editor's Note This study led by researchers at State University of New York, Binghamton, finds that social-distancing measures implemented by states in the early months of the COVID-19 pandemic resulted in smaller death rates, but led to larger second waves. Conversely, social-distancing measures implemented by states later in the pandemic…

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 This study by researchers at the University of Louisville finds that state mask mandates did not help slow COVID-19 transmission. The analysis compares COVID-19 case growth rates in 33 states that imposed statewide mask mandates on or before August 2, 2020, with states that imposed mask mandates after…

Editor's Note Two studies suggest that immunity to COVID-19 persists for at least a year and perhaps a lifetime, the May 26 New York Times reports. Researchers focused on memory B cells, which retain a memory of the COVID-19 virus. They found that even though the patients’ antibody levels fell…

Editor's Note A study by the Riken research institute and Kobe University using Fugaku, the world’s fastest supercomputer, finds that wearing two masks offers little benefit in preventing the spread of COVID-19 compared to one well-fitted disposable mask, the March 4 Reuters reports. The researchers found that tightly-fitted surgical masks…

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…
