How the common cold can provide protection against COVID-19

In a recent study, researchers found that prior infection with the rhinovirus can provide a more effective immune response against SARS-CoV-2 infection.

Myocarditis after SARS-CoV-2 vaccine

A group of Italian researchers has published a study in the Canadian Journal of Cardiology (CJC), that explores a rare case of progressive dyspnea and constrictive retrosternal pain after a SARS-CoV-2 vaccine.

Antibody combination REGEN-COV prevents symptomatic disease following SARS-CoV-2 infection

Researchers in the United States have demonstrated the effectiveness of early treatment with REGEN-COV™ at preventing symptomatic disease among people infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

Can rapid antigen tests help screen for COVID-19?

The spread of SARS-CoV-2 is driven by the high proportion of asymptomatic and very mild infections, allowing people to move around and engage in public activity normally. There are many modeling studies that suggest that large-scale screening for the presence of this virus can help curb transmission at this point, from people with few or no symptoms. A new study points out the accuracy of SARS-CoV-2 antigen-detection rapid diagnostic tests for this purpose when used at the point-of-care.

Teachers and school staff should be prioritised for COVID vaccines

In a communication paper recently published in the Journal of Paediatrics and Child Health by Koirala et al. (June 8th, 2021), it is argued that Australian schools should remain open, with proper testing, tracing, and quarantine protocols in place.

Role of traditional medicine against SARS-CoV-2

A group of researchers at Kannur University reviewed selected papers and in silico work on potential drug leads that could be used to manage COVID-19.

Innovative protocol that processes saliva samples before testing may improve COVID-19 detection

The collection of nasopharyngeal swab (NPS) samples for COVID-19 diagnostic testing poses challenges including exposure risk to healthcare workers and supply chain constraints. Saliva samples are easier to collect but can be mixed with mucus or blood, and some studies have found they produce less accurate results.

SARS-CoV-2 B.1.1.345 variant carrying E484K mutation detected in New York

The report, published in the journal Clinical Infectious Diseases, revealed that the variant detected has been spreading at an alarming rate since November. By February 2021, it accounted for 12.3 percent of all cases in the area.

Could 3D printed swabs be used to collect COVID-19 test samples?

Researchers have evaluated 3D printed sample collection swabs made in-house and found them to be a reliable alternative to commercial swabs.

Researchers find natural metabolites help SARS-CoV-2 escape antibodies

An international team of scientists has identified a human molecule — biliverdin — as a potential severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) target. The binding of the heme metabolite to the N-terminal domain of SARS-CoV-2 is associated with the virus’s ability to dodge the immune system by suppressing antibody binding to the spike protein.

B.1.617.2 variant of SARS-CoV-2 is partially resistant to antibody-mediated neutralization

A team of scientists from France has recently conducted a study to evaluate the sensitivity of the B.1.617 variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to antibody-mediated neutralization.

New, portable saliva screening test detects SARS-CoV-2 in five-minutes

International research led by Monash University and the Peter Doherty Institute for Infection and Immunity has achieved a proof of concept for a new, fast, portable saliva screening test that uses an infrared light technology to confirm infection with SARS-CoV-2.

Person infected with SARS-CoV-2 can transmit infection to three to five other people

What started as the preliminary analysis of routine laboratory data has since evolved into the largest-ever study of viral load levels in patients with SARS-CoV-2.

Researchers develop a novel probiotic formulation with high anti-SARS-CoV-2 potency

A team of international scientists recently conducted a randomized clinical trial to assess the safety and efficacy profiles of a novel probiotic formulation in symptomatic coronavirus disease 2019 (COVID-19) patients. The findings indicate that the probiotic formulation is highly effective in reducing symptom severity in COVID-19 patients without causing any adverse events.

SARS-CoV-2 UK variant may induce more inflammation, study suggests

Since COVID-19 was first detected in December 2019 in Wuhan, China, many different variants of its causative virus – SARS-CoV-2 – have emerged. Through increased viral fitness, some of these have risen to predominance over earlier variants in a remarkably short period of time. New research, by a team of scientists at major institutions in France, examines the reasons behind this phenomenon in one such variant of concern (VOC), the so-called UK variant.

New testing protocol for SARS-CoV-2 can process thousands of samples within 48 hours

Researchers at the Vienna BioCenter designed a testing protocol for SARS-CoV-2 that can process tens of thousands of samples in less than 48 hours. The method, called SARSeq, is published in the journal Nature Communications and could be adapted to many more pathogens.

Research looks at viral presence around hospitalized COVID-19 patients

Researchers in Canada aimed to determine the burden of SARS-CoV-2 in the air and on surfaces in the rooms of patients hospitalized with COVID-19.
