Round-up: COVID-19 July 2021 (Part Two)

It’s hard to keep track of all of the latest news and research surrounding the coronavirus – so we have done it for you with our latest COVID-19 round-up!


At the time of writing, there have been:

  • 192,848,567 cases
  • 4,142,769 deaths
  • 175,364,116 recoveries


  • Researchers have created an atlas that charts how 152 different antibodies attack SARS-CoV-2 spike protein variants. (Tong et al, 2021)
  • New research has found that SARS-CoV-2 mutations are occurring in similar locations to that of its closest relatives. (LaTourrette et al, 2021)
  • A new study has found that people who develop five or more symptoms in the first week of infection are more likely to develop long COVID. (Aiyegbusi et al, 2021)
  • Researchers have produced a stem cell model that demonstrates a potential route of entry of SARS-CoV-2 into the human brain. (Wang et al, 2021)
  • An international team of researchers has shown that the L452R mutation of the SARS-CoV-2 spike protein, which is common to two mutant strains (Epsilon and Delta), is involved in cellular immunity evasion via the human leukocyte antigen (HLA) A24. (Motozono et al, 2021)
  • In cell culture studies, researchers have found that the SARS-CoV-2 variant B.1.617 is less sensitive to inhibition by antibodies. (Hoffmann et al, 2021)
  • Researchers have developed an innovative method to detect and quantify the more transmissible B.1.1.7 (Alpha) variant of concern via wastewater epidemiology. (Lee et al, 2021)

Other news

  • In a recent Viewpoint article, Dana Crawford of Case Western Reserve University argued that the lack of sequencing of SARS-CoV-2 variants by the U.S. and other countries is impeding the global response to the COVID-19 pandemic. (Crawford and Williams, 2021)
  • Researchers from Florida Atlantic University’s College of Engineering and Computer Science are the first to model COVID-19 completion versus cessation in clinical trials using machine learning algorithms and ensemble learning. (Elkin and Zhu, 2021)
