Genomic analysis provides clues about SARS-CoV-2 ancestry and transmission

Researchers in the UK conducting a genomic analysis of severe acute respiratory virus syndrome coronavirus 2 (SARS-CoV-2) and SARS-like coronaviruses in the bat and pangolin have identified strong host-associated divergences that could provide clues about the ancestry and interspecies transmission of SARS-CoV-2.

SARS-CoV-2 spike protein antibodies can persist up to 200 days after symptom onset

Researchers report SARS-CoV-2 antibodies to the spike protein (S protein) can persist 200 days after symptom onset, but that antibodies to the nucleoprotein (N protein) can reduce much more rapidly.

SARS-CoV-2 versus Zika: Comparing and contrasting the flow of research

An interesting study published on the preprint server medRxiv in November 2020, dealing not with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that is the cause of the COVID-19 pandemic, but with the publications that have appeared as a consequence of the outbreak, comparing them with the similar trove of publications that followed the Zika virus outbreak in 2016.

Bariatric surgery linked to lower risk of hospital and intensive care unit admission

A Cleveland Clinic study shows that among patients who have obesity and who tested positive for COVID-19, a past history of bariatric surgery was significantly associated with a lower risk of hospital and intensive care unit admission.

BCG vaccination appears to trigger cross-reactive SARS-CoV-2-specific T cell response

Recently, researchers from the Monash University and Monash Medical Centre, Clayton, Victoria, Australia, investigated whether peptide sensitization using BCG can produce cross-reactive T cells specific to SARS-CoV-2. Their study is published on the preprint server, medRxiv.

Mefloquine shows potential as anti-SARS-CoV-2 drug

A team of scientists from Japan has identified the approved anti-material drug, mefloquine, as a potential candidate to treat severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Specifically, mefloquine has been shown to prevent the entry of SARS-CoV-2 into host cells and reduce the viral load in vitro.
