SARS-CoV-2 D614G variant enhances infectivity, replication and transmission

Researchers in the United States and Japan have conducted a study showing a common mutation in the spike protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) - the agent that causes coronavirus disease 2019 (COVD-19) - enhances the infectivity, replication, and early transmission of the virus.

Danish vs. Swedish data shows social interaction major risk factor for SARS-CoV-2 infection

A new study published on the preprint server medRxiv* in September 2020 compares the prevalence of antibodies to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in Danish and Swedish healthcare workers, to conclude that “social interaction is one of the biggest risk factors for getting infected with SARS-CoV-2.”

A TLR2 agonist reduces SARS-CoV-2 in upper respiratory tract of ferret model

In a recent bioRxiv* preprint paper, Professor Miles W. Carroll et al. study an agonist for reducing the SARS-CoV-2's viral load. They show that prophylactic intra-nasal administration of TLR2/6 (toll-like receptor) agonist, INNA-051, reduces viral RNA in the nose and throat, in a ferret model.

Sleep apnea increases risk of severe COVID 19

Coronavirus disease (COVID-19) is a respiratory disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. A subset of COVID-19 patients face a severe form of the disease with hospitalization, respiratory failure, or death. Severe COVID-19 is primarily characterized by respiratory distress, and the common risk factors are older age, obesity, cardiovascular disease, diabetes, and poor lung function.

College football crowds could impact COVID-19 spread

The observed increase in COVID-19 cases coinciding with the reopening of college campuses all over the US has drawn intense scientific attention. A recent paper, by Washington State University researchers, published on the preprint server medRxiv* in September 2020 reports that this threat is directly linked to the holding of in-person sporting events on these campuses.

New graphical tool to identify potent neutralizing antibodies against SARS-CoV-2

A new study by researchers at the Indian Institute of Science and the University of Queensland and published on the preprint server medRxiv in September 2020 discusses using a novel tool to identify the most effective among currently known anti-SARS-CoV-2 NAbs.

Australian scientists develop a nasal spray that could stop SARS-CoV-2 infection

The novel product, called INNA-051, is being developed by Ena Respiratory, and laboratory experiments have shown that it reduced viral replication by as much as 96 percent in the animal study. Spearheaded by Public Health England’s (PHE) Deputy Director, Professor Miles Carroll, the new study described the potential treatment and has been published in the open-source preprint server bioRxiv*.

Case fatality rates for COVID-19 and health indicators

Researchers from Turkey and Switzerland collaborated to study the nation-specific case fatality rates for COVID-19 caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The pandemic has affected around 33.5 million people worldwide and killed over 1 million making it one of the largest global health crises in recent memory.

SARS-CoV-2 infects human embryonic epithelial and lung cells

As COVID-19 continues to spread the world over, investigators are still trying to understand how it ravages the human body. A recent study published on the preprint server bioRxiv in September 2020 shows that the virus is capable of infecting human embryonic cells that are destined to form the epithelial surfaces of the body, both internal and external, as well as lung cells.

Discovery of specific kinase as a novel drug target against SARS-CoV-2 and other coronaviruses

By using a modern genome-wide knockout approach to single out coronavirus host factors in human cells, researchers from Rega Institute in Belgium discovered a potential new target that might be exploited for developing drugs against the ongoing coronavirus disease (COVID-19) pandemic, but also future outbreaks of highly pathogenic coronaviruses

Fasting blood glucose levels upon admission tied to COVID-19 prognosis, study finds

In the study, which appeared on the pre-print open-source medRxiv* server, the investigators aimed to determine the prognostic value of blood glucose in predicting outcomes in COVID-19 disease, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

SARS-CoV-2 re-infection is real but rare: Case study

Now, American researchers have looked at all reported cases of re-infection and the possible reasons behind them. Their study titled, “Re-infection with SARS-CoV-2 and Failure of Humoral Immunity: a case report,” is published online on the preprint server medRxiv in September 2020.

J&J's COVID-19 vaccine shows potent immune response in phase 2 human trial

A multicenter phase 1/2a randomized, double-blinded, placebo-controlled clinical trial has been conducted recently to evaluate the safety, reactogenicity, and immunogenicity of a non-replicating adenovirus-based vaccine, namely Ad26.COV2.S against severe acute respiratory coronavirus 2 (SARS-CoV-2) infection.

Hamsters and ferrets clear low dose SARS-CoV-2 infection in 14 days

A recent study by French researchers has demonstrated that experimental exposure to severe acute respiratory coronavirus 2 (SARS-CoV-2) is capable of inducing mild infection in hamsters and ferrets within 7 – 10 days of exposure. However, the infection completely resolves within 14 days. The study is currently available on the bioRxiv preprint server.
