Study shows P681H mutation is becoming globally prevalent among SARS-CoV-2 sequences

In a recent bioRxiv preprint study, researchers from the University of Hawaii showed that the S gene of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is continuously mutating according to the sequence and phylogenetic analysis.

Naturally selected mutations of SARS-CoV-2 easily duplicated in vitro

In a recent and timely paper, currently available on the bioRxiv preprint server, researchers from Israel and France demonstrated how in vitro evolution of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) receptor-binding domain (RBD) follows contagious mutation spread – but can also generate an efficient infection inhibitor.

Researchers pinpoint spike protein regions as targets for passive and active COVID-19 vaccines

Researchers at Stanford University School of Medicine have identified regions of the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that have relatively few mutations and might therefore serve as important targets for prophylactic agents against coronavirus disease 2019 (COVID-19).

Modeling study sheds light on SARS-CoV-2 genome packaging

Researchers at the University of North Carolina at Chapel Hill have conducted a study exploring how the spatial patterning of certain genomic RNA regions in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) promotes compaction, packaging, and cyclization of the viral genome.

New test detects SARS-CoV-2 in less than 5 mins

A fast and accurate virus detection strategy is very crucial to reduce the rate of transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the pathogen responsible for COVID-19. The global scientific research community responded to this unprecedented demand in diagnostic testing by developing several detection platforms, the most sensitive of which detect the viral RNA.

How do SARS-CoV-2 antibodies change over time in recovered patients?

Researchers studied convalescent plasma from recovered coronavirus disease 2019 (COVID-19) patients, with samples collected up to 34 weeks after recovery. They found IgG antibodies gradually declined with a median half-life of about 60 days.

Airborne transmission of SARS-CoV-2 is possible in enclosed environments, a study finds

A team of scientists recently revealed that inside a closed room, the chance of airborne SARS-CoV-2 infection directly depends on the number of symptomatic COVID-19 patients in the room and the duration of exposure.

Researchers develop a low-cost, saliva-optimized RT-LAMP assay for faster detection of SARS-CoV-2

SARS-CoV-2 pandemic has highlighted the shortcomings in emergency response globally and has driven a massive demand for in vitro diagnostic testing technologies. In order to address these issues, researchers from the US recently used the new pH dye LAMPShade Violet (LSV) in RT-LAMP. LSV has better visual contrast between high and low pH and a stronger inflection point, both of which enable easy interpretation of results and reduces ambiguity.

Link between fever, diarrhea, severe COVID-19, and persistent anti-SARS-CoV-2 antibodies

A new preprint research paper appearing on the medRxiv server describes a link between the persistence of neutralizing antibodies against the virus, disease severity, and specific COVID-19 symptoms.

High-affinity SARS-CoV-2 RBD drives mutation spread, forms basis of new COVID-19 inhibitor

Now, an intriguing recent study appeared on the bioRxiv * preprint server describes the use of in vitro evolution to elicit affinity maturation of the viral receptor-binding domain (RBD) of the spike protein to bind the host cell angiotensin-converting enzyme 2 (ACE2) with greater affinity.

Potential role of chitinase 3-like-1 in severity of COVID-19

Now, an intriguing preprint research paper on the bioRxiv server reports the identification of an enzyme called chitinase 3-like-1 (CHI3L1) that mediates this age-dependent impact of the virus and could serve as a powerful therapeutic approach in mitigating the severity of COVID-19 in this high-risk group.

Antibodies and inflammatory markers are pervasive in colostrum of SARS-CoV-2 infected women

A recent study, currently available on the medRxiv* preprint server, is among the first to reveal the presence of antibodies against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in colostrum and to demonstrate elevated cytokine levels in colostrum from women exposed to the virus.

7 Jan 2021

Potential treatment approach to new COVID-19 variant

Researchers in the United States have demonstrated a potential new approach to treating infection with the new variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

Facemasks significantly reduce simulated SARS-CoV-2 transmission in classroom setting

Researchers at the University of Wisconsin-Madison have conducted a study showing that wearing facemasks in the classroom setting can be highly effective at reducing the aerosol transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

How has the COVID-19 pandemic affected the mental health of older adults? A UK case study

A team of researchers at University College London, UK, recently explored how the COVID-19 pandemic has affected the mental health of older adults across Britain.

SARS-CoV-2 viral load in saliva may be linked to COVID-19 disease severity

Researchers at Yale University School of Medicine found that SARS-CoV-2 viral loads in saliva are higher for patients with associated risk factors and underlying conditions that lead to severe COVID-19 and death. Thus, saliva viral loads could be used to predict disease severity.

Males at higher risk of severe COVID-19 and mortality in Indian case study

A new US-based study by researchers at Dartmouth College, the Development Data Lab, IDFC Institute, Johns Hopkins University, and the University of Chicago shows that the infection fatality rate (IFR) could be twice as high for men compared to women and increases much less at older ages compared to high-income countries.

Which strain should SARS-CoV-2 vaccine candidates target?

A researcher at Clemson University, USA, has recently explored how governments might effectively combat the pandemic through strategic vaccination as new variants and strains of the virus emerge. The study suggests that vaccine candidates should target the fast-spreading variant, even when the initial prevalence is much lower.

Severe COVID-19 recovered patients do not display long-lasting adaptive immune responses, finds study

A team of scientists from the University of Valencia and INCLIVA Health Research Institute, Spain, has recently investigated the durability of immune responses specifically developed against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative pathogen of coronavirus disease 2019 (COVID-19).

7 Jan 2021

Danish study suggests local lockdown had no effect on SARS-CoV-2 infection rate

The onset of the coronavirus disease 2019 (COVID-19) pandemic led to severe restrictions on public mobility and interaction, national or state-wide lockdowns, school and workplace closures, and curfews. The result was widespread economic hardship, in addition to the toll on health.
