Patient with hypertension or cardiovascular diseases experienced critical disease progression with COVID-19

COVID-19 patients who also suffer from high blood pressure are more likely to fall severely ill with the disease, which also leaves them at greater risk of death.

SARS-CoV-2 exposure in England could be double reported seroprevalence

A new study that recently appeared on the preprint server medRxiv* makes use of a combined method to estimate population exposure to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), taking into account the fact that patients who recover from the infection often do not have circulating antibodies against the virus.

The mystery of Giglio island’s resistance to COVID-19

An intriguing new study explores the mechanisms by which an Italian island called Giglio remained resistant to coronavirus disease 2019 (COVID-19) even after much exposure.

Study supports continuing phase 3 trials of Ad26.COV2.S SARS-CoV-2 vaccine

An international team of researchers has provided further evidence to confirm the immunogenicity and efficacy of a recombinant adenovirus vaccine currently being tested in phase 3 trials for its ability to protect against infection with severe acute respiratory coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

Extract of medicinal plant Artemisia annua interferes with replication of SARS-CoV-2 in vitro

Researchers in the United States have shown that extracts of an aromatic herb called Artemisia annua inhibit the replication of severe acute respiratory coronavirus (SARS-CoV-2) – the agent responsible for the current coronavirus disease 2019 (COVID-19) pandemic.

Antibody recognition of linear SARS-CoV-2 epitopes preserved in mutated B.1.1.7 strain

In a recent medRxiv research paper, the US scientists examined the effects of non-synonymous mutations in the circulating B.1.1.7 strain of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on linear antibody epitope signal for viral spike glycoprotein and nucleoprotein – and demonstrated that mutations should not result in immune evasion.

Researchers demonstrate SARS-CoV-2 infection in human lung bronchioalveolar tissue model

Development of an in vitro human-derived tissue model for studying virus infection and disease progression in the alveolar cells of the lungs responsible for oxygen and carbon dioxide exchange with the blood might enable the study of possible therapies for acute respiratory distress syndrome (ARDS) triggered by SARS-CoV-2.

Study finds association between severity of COVID-19 and shorter telomeres

Patients with severe COVID-19 disease have significantly shorter telomeres, according to a study conducted by researchers at the Spanish National Cancer Research Centre in collaboration with the COVID-IFEMA Field Hospital, published in the journal Aging.

Over half of COVID-19 cases are spread by asymptomatic carriers, CDC study finds

In a new study conducted by researchers at the U.S. Centers for Disease Control and Prevention (CDC), over half of SARS-CoV-2 infections are believed to be transmitted asymptomatically.

Sustained immune response memory detected in recovered COVID-19 patients

A team of researchers at the University of Washington School of Medicine has found that people who had mild COVID-19 developed a multi-layered immune response against SARS-Cov-2. The researchers detected neutralizing antibodies against the virus for at least three months after recovering from the infection.

Vimentin could be a major co-factor that aids SARS-CoV-2 infection

A recent study has found that extracellular vimentin can bind to SARS-CoV-2 spike protein in vitro, and antibodies against vimentin can decrease virus infectivity by up to 80%. This suggests vimentin could aid the virus’s binding to host cells and help in infection.

Could Ivermectin be an effective antiviral against SARS-CoV-2?

A double-blind, randomized, placebo-controlled clinical trial has recently demonstrated that Ivermectin, an anti-parasitic drug, can reduce in-hospital mortality rate of COVID-19 patients.

11 Jan 2021

SARS-CoV-2-induced innate immune responses may vary with disease severity, finds study

Scientists from Germany and China recently conducted a large meta-analysis using transcriptome data of SARS-CoV-2 to evaluate the routes of viral entry and the characteristics of innate immune responses induced by SARS-CoV-2 infection.

How effective are masks in preventing SARS-CoV-2 transmission?

Can face masks protect against SARS-CoV-2 infection? Faruque Ahmad, MD, recently explored the role of face masks in mitigating the coronavirus disease 2019 (COVID-19), caused by SARS-CoV-2.

11 Jan 2021

Seroprevalence and asymptomatic carrier status of SARS-CoV-2 in China

As asymptomatic transmission chains play a role in SARS-CoV-2’s viral spread, a new study by researchers in Wuhan, China, investigated the seroprevalence and asymptomatic carrier status of SARS-CoV-2 in the region.

Schlieren techniques demonstrate patterns of exhaled air spread from wind instruments and singers

In an interesting new research paper published recently on the bioRxiv preprint server, scientists describe the dispersal of exhaled air, potentially infected, from singers and those playing wind instruments, using Schlieren techniques, a visual process that is used to photograph the flow of fluids of varying density. This could help assess measures to assess the actual spread of infectious droplets or aerosols in such situations.

Tetherin downregulation by SARS-CoV-2 enhances viral spread

A new preprint research paper published on the bioRxiv server describes the role of a host protein called tetherin in the spread of the novel coronavirus.

Synthetic lung organoids provide high-throughput platform to identify new cellular targets of SARS-CoV-2

An interesting new study published on the bioRxiv preprint server describes a new platform that allows a high-throughput workflow to generate matched human lung buds in the tens of thousands. This allows researchers to study SARS-CoV-2 infection and therapeutics in lung tissue that mirrors the key aspects of human lung development.

10 Jan 2021

Large-scale genome sequencing shows how SARS-CoV-2 mutated

A new study published on the preprint server bioRxiv* describes the results of genomic sequencing of the virus, which may help trace the routes of transmission of the virus from person to person, and from country to country.

10 Jan 2021

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.
