  • 234,157,620 cases
  • 4,790,062 deaths
  • 210,951,931 recoveries


  • Brazilian researchers have taken the first steps toward understanding why some people are naturally resistant to infection by SARS-CoV-2. (Castelli et al, 2021)
  • Researchers have shown how SARS-CoV-2 proteases attack the cell and how they can be targeted to stop viral replication using existing drugs. (Meyer et al, 2021)
  • A unique type of tiny antibody, produced by llamas, could provide a new treatment against COVID-19. (Huo et al, 2021)
  • New research has reported that a component of the human interferon system that activates SARS-CoV-2 cellular defences is defective in a proportion of individuals. (Wickenhagen et al, 2021)
  • Scientists at La Jolla Institute for Immunology (LJI) have published a detailed map of where human antibodies bind to SARS-CoV-2. (Hastie et al, 2021)
  • A new study has found that combined measurement of granulocytes and well-known biomarkers in the blood can predict COVID-19 severity. (Lourda et al, 2021)
  • New research has reported the identification of a cell surface protein, CD47, that may be critical in contributing to severe forms of COVID-19. (McLaughlin et al, 2021)
  • Researchers have found that the nasal microbiota may hold clues as to which individuals will develop symptoms from SARS-CoV-2. (Kolhe et al, 2021)
  • A version of SARS-CoV-2 has been modified to glow brightly in cells and animal tissues, enabling researchers to track the spread and intensity of viral infection. (Ye et al, 2021)
  • Penn State researchers have created a new tool that can predict with reasonable accuracy the amino acid changes in the virus’ spike protein that may make variants more infectious. (Chen et al, 2021)

Other news

  • The University of Oxford and Oracle’s cloud system is being used by researchers to help identify COVID-19 variants faster. (Oracle, 2021)
  • According to new research, the COVID-19 pandemic has triggered the biggest decrease in life expectancy since World War II. (Aburto et al, 2021)
