Elegant, efficient way to find recombinant SARS-CoV-2 viruses from >85,000 genomes

The low divergence of near-identical genomes that are sequenced in short periods presents a statistical challenge that is not addressed by methods available currently. In a recent bioRxiv** paper, Ales Varabyou et al. from John Hopkins University present an efficient method designed to detect recombination and reassortment events between clades of viral genomes – a new algorithm called ‘Bolotie’.

Study on domestic cats and dogs in COVID-19+ households

A recent survey conducted by a team of scientists from France reveals that pets living with confirmed coronavirus disease 2019 (COVID-19) patients have a high prevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies. The study is currently available on the bioRxiv* preprint server.

No discernable difference in SARS-CoV-2 viral loads of young children versus older children and adults

Sharline Madera et al. , in a recent medRxiv* preprint paper, show a detailed investigation of viral nucleic acid among young children and adults, involving over 5,000 cases confirmed by RT-PCR (Reverse Transcriptase – Polymerase Chain Reaction) assay.

Bat and pangolin coronavirus structure sheds light on SARS-CoV-2 evolution

Researchers at Tsinghua University, Beijing, have conducted a study providing possible new insights into the evolution and cross-species transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the agent responsible for the current coronavirus disease 2019 (COVID-19) pandemic.

UV-C irradiation rapidly inactivates SARS-CoV-2 on surfaces

Researchers at University Hospital Tübingen, Germany, have shown that ultraviolet C (UV-C) irradiation effectively inactivates surface-dried preparations of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the agent that causes coronavirus disease 2019 (COVID-19).

Bioinformatics analysis reveals genes and pathways shared in COVID-19 disease and comorbidities

Using bioinformatics approaches, researchers have identified genes and pathways shared among patients with comorbidities and having severe COVID-19. The research is published on the preprint server bioRxiv in September 2020.

Shielding strategy could be ineffective in reducing COVID-19 prevalence and mortality

With the recognition that certain subgroups of the population seemed to have a higher risk of developing severe disease following infection, some countries put shielding policies into place to protect them from infection.

A subunit SARS-CoV-2 vaccine may offer broader protection against virus

A new study published in the preprint server bioRxiv in September 2020 reports on the structure of this protein, as revealed by cryo-electron microscopy (cryoEM).

23 Sep 2020

Molecular dynamic simulations reveal detailed spike-ACE2 interactions

The current COVID-19 pandemic has spread throughout the world. Caused by a single-stranded RNA betacoronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which is closely related to but much more infectious than the earlier highly pathogenic betacoronaviruses SARS and MERS-CoV, has impacted social, economic, and physical health to an unimaginable extent.

Common genetic variants may influence susceptibility to COVID-19

Researchers in the United States and Japan have conducted a study suggesting that a commonly occurring genetic variant influences susceptibility to infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the agent that causes coronavirus disease 2019 (COVID-19).

Study suggests herd immunity to COVID-19 in Brazilian city of Manaus

According to the study estimates, the transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes COVID-19 – rapidly increased in Manaus between March and April, before slowly declining between May and September.

Baseline T cell signatures predict clinical outcomes of SARS-CoV infection

In a recent bioRxiv preprint paper, researchers from the Department of Medical Informatics and Clinical Epidemiology, Oregon Health & Science University, Portland, OR, and Department of Global Health, University of Washington, Seattle, WA, discuss their study in mice that undergo detailed immunophenotyping before getting infected with SARS-CoV.

Expert warns that COVID-19 cases in the UK could reach 50,000 per day

In the United Kingdom, health experts said that the country could face an exponentially growing death rate from COVID-19 within weeks unless urgent action is taken to control the spread of the virus. At present, the country has the highest official COVID-19 death toll in Europe and the fifth-largest across the globe.

CDC withdraws guideline on SARS-CoV-2 airborne spread

The U.S. Centers for Disease Control and Prevention (CDC) recently published a new guideline, recognizing that the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can spread via aerosols. Now, the health agency takes back its statement by deleting the updates published on Sept. 18.

Acquisition of a natural mutation primes SARS-CoV-2 for neutralization by a cross-reactive antibody

A team of scientists from the United States reveals that the acquisition of a natural mutation makes severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) susceptible to neutralization by a cross-reactive SARS-CoV antibody. The study is currently available on the bioRxiv* preprint server.

Confirmed early re-infection with SARS-CoV-2

As scientists strive to develop commercially viable and effective antivirals and vaccines to counter the growing COVID-19 pandemic, there is considerable uncertainty about how long and how durable the immunity induced by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is. A new paper recently published in the journal Clinical Infectious Disease in September 2020 reports a confirmed case of re-infection with this virus following recovery.
