SARS-CoV-2 variants show distinct humoral response and transcriptional profiles in hamster model

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a novel, highly infectious respiratory virus, and the causative agent of coronavirus disease 2019 (COVID-19) pandemic. SARS-CoV-2, which first originated in Wuhan, in Hubei province of China, is a member of the Coronavirdae family and has a large, non-segmented RNA genome.

High individual-level variability in SARS-CoV-2 shedding may explain superspreading

Researchers in the United States have provided a high-resolution description of the viral dynamics involved in acute infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

Study identifies SARS-CoV-2 spike conformation exposing potential new therapeutic targets

Researchers in the United States have demonstrated that the viral spike protein used by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to infect host cells adopts an open conformation exposing novel epitopes that could serve as targets for therapeutic strategies to protect against coronavirus disease 2019 (COVID-19).

Israeli study of breakthrough infections following full BNT-Pfizer vaccination, 40% immunocompromised

Severe forms of coronavirus disease (COVID-19) linked to high mortality rates might arise in a minority of fully-vaccinated individuals with many co-occurring medical conditions, finds a recent study by Israeli researchers published in the journal Clinical Microbiology and Infection.

Wildtype SARS-CoV-2 more widespread in 10-19-year-olds prior to vaccine availability in the USA

A new study aimed to investigate the susceptibility of adolescents as compared to older adults in the United States during the summer of 2020.

Neutralizing aptamers block SARS-CoV-2 infection in vitro

A new study describes the clinical utility of aptamers against SARS-CoV-2.

Blood test could be a simple and effective method for monitoring SARS-CoV-2 infection

A blood test that quantifies the protein ACE2, the cellular protein which allows entry of the coronavirus into cells, as well as ACE2 fragments, produced as a result of interaction with the virus, could be a simple and effective method for monitoring SARS-CoV-2 infection, according to a study led by Javier Sáez-Valero, from the UMH-CSIC Neurosciences Institute in Alicante, published in FASEB Journal.

Could aspirin intake reduce mortality risk in COVID-19 patients?

Scientists from the Michigan State University, USA, have conducted a systematic review and meta-analysis to compare mortality rate in coronavirus disease 2019 (COVID-19) patients who are aspirin users or non-users. The Findings reveal that the use of aspirin is associated with a significant reduction in overall and in-hospital mortality rates.

Scientists develop mouse-specific SARS-CoV-2 strains that efficiently replicate in standard laboratory mice

A team of scientists in France recently developed a mouse-adapted strain of SARS-CoV-2 that efficiently replicates in the lungs of standard laboratory mice and induces mild to moderate disease. The study is currently available on the bioRxiv* preprint server.

Study examines asymptomatic, presymptomatic and symptomatic transmission dynamics of SARS-CoV-2

A new preprint, available on the medRxiv* server, describes how researchers found at least a third of infected individuals to be asymptomatic, but that a fifth of them successfully passed on the virus to others. In comparison, about a quarter of symptomatic cases did so, especially when the symptoms included fever, cough and shortness of breath. In these circumstances, up to 30% of them transmitted the virus.

Colonization by SARS-CoV-2 not synonymous with infection, screening study highlights

A new study released as a preprint on the medRxiv* server throws cold water on this notion, however, by demonstrating that in a set of asymptomatic cases, less than a tenth actually had evidence of SARS-CoV-2 infection. This finding has serious implications for the practices mentioned above, since they may be neither justifiable nor cost-effective as means to break the chain of viral transmission.

“React and inject”: synthetic peptide-modified nanodiamonds as emergency pan-coronavirus vaccines

A recent study published in the MDPI journal, Pathogens, describes a coronavirus peptide vaccine antigen in the form of nanodiamond-based formulations, that demonstrated a robust and long-lasting immune response. The nanodiamonds proved to be a powerful and versatile platform for antigen conjugation. This could make it a safe and effective strategy for the production of off-the-shelf vaccines against multiple coronaviruses.

Study reports low risk for COVID-19 in Emergency Medical Service personnel exposed to aerosol-generating procedures

The U.S. Centers for Disease Control and Prevention (CDC) reports that emergency medical service personnel exposed to aerosol-generating procedures (AGP) on COVID-19 patients are generally at low risk of infection. The findings, published in CDC’s Emerging Infectious Diseases, support clinical strategies that maintain established and evidence-based practices for emergency conditions.

Study evaluates the prevalence of COVID-19 symptoms more than seven months after diagnosis

The SARS-CoV-2 virus, responsible for the COVID-19 disease, can cause symptoms that last for several weeks to months. The most common are persistent fatigue, shortness of breath, cardiac symptoms, neurologic symptoms and psychiatric manifestations.
