Ferret study shows SARS-CoV-2 airborne transmission dynamics

A team of researchers led by Sander Herfst from Erasmus University Medical Center in The Netherlands suggests severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) could spread through the air at a one-meter distance and cause infection in a new ferret model study.

SARS-CoV-2 in wastewater may pose risks to marine mammals

Endangered marine mammals — seals, dolphins, whales, and otters — are almost as vulnerable as humans in becoming infected from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Researchers from the Dalhousie University in Canada published a study in Science of The Total Environment that found human wastewater as a potential mode of coronavirus transmission to animals.

Business Risk Index quantifies the potential risk of COVID-19 transmission

Just one year after the World Health Organization declared the novel coronavirus a global pandemic, three COVID-19 vaccines are available in the United States, and more than 2 million Americans are receiving shots each day.

Study: Slow walkers have higher risk of contracting severe COVID-19

SLOW walkers are almost four times more likely to die from COVID-19, and have over twice the risk of contracting a severe version of the virus, according to a team of researchers from the National Institute for Health Research (NIHR) Leicester Biomedical Research Centre led by Professor Tom Yates at the University of Leicester.

New strategy may change the course of evolving COVID-19 pandemic

Launched in April 2020 by the World Health Organization (WHO), European Commission, France and The Bill & Melinda Gates Foundation, the ACT Accelerator is a partnership of leading public health agencies with equity at its heart.

Study explores how SARS-CoV-2 mutations produce antibody resistance and enhanced transmissibility

An interesting new study deals with the effects of the natural mutations in the spike antigen of the SARS-CoV-2, the pathogen that is responsible for the ongoing coronavirus disease pandemic.

Backtracking occurs within SARS-CoV-2 replication-transcription complex

Researchers continue to achieve a better understanding of SARS-CoV-2, the virus behind the ongoing COVID-19 pandemic. One such effort has been reported in a new preprint on the bioRxiv server, dealing with the phenomenon of backtracking.

The role of RNA capping of SARS-CoV-2 in immunity evasion

The SARS-CoV-2 pathogen successfully uses multiple immune evasion mechanisms to achieve infection within its host. An intriguing new study describes one such process, which may help develop drugs to counteract the virus more effectively.

New study tests how mutations in SARS-CoV-2 affect antibody neutralization

Using pseudoviruses with single amino acid substitutions, researchers found that mutations in SARS-CoV-2 reduce monoclonal antibody neutralization differently. However, convalescent sera samples did not lose neutralization potency many and were also effective against the B.1.1.7 (UK-derived) strain.

Study suggests daily testing instead of self-isolation for contacts of SARS-CoV-2 cases

In the study, which appeared in the pre-print server medRxiv*, the researchers aimed to evaluate the acceptability and engagement with the daily testing as an alternative to self-isolation. They found that daily testing is acceptable and may help promote adherence to self-isolation.

New SARS-CoV-2 lineage has spread across many Brazilian states

Researchers in Brazil have identified the emergence of a new lineage of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in Brazil that has spread across multiple states in the country.

Chimeric vaccines may provide universal protection against viruses like SARS-CoV-2

Researchers in the United States have developed “chimeric” vaccines that provided cross-protection against different strains of sarbecovirus in mice, including the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that causes coronavirus disease 2019 (COVID-19).

Study unveils SARS-CoV-2 persistence and contamination concentration on common surfaces

A recent environmental study from the United Kingdom, currently available on the bioRxiv preprint server, shows that certain common surfaces could represent an infectious risk if contaminated with high concentrations of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – albeit the level of viable viral particles is likely to be low.

Scientists discover how novel pathogens promote colorectal cancer development

Do BMMFs, the novel infectious agents found in dairy products and bovine sera, play a role in the development of colorectal cancer? Scientists led by Harald zur Hausen detected the pathogens in colorectal cancer patients in close proximity to tumors.

Researchers use wastewater to monitor prevalence of COVID-19 for first time in United Arab Emirates

Early warning systems are vital in preventing surging waves of the coronavirus disease 2019 (COVID-19) pandemic. Researchers have used wastewater samples to detect the spread of the virus in the United Arab Emirates from municipal and commercial aircraft, the first of its kind in the country, and the largest to date.

White-tailed deer susceptible to SARS-CoV-2, finds study

White-tailed deer have been observed to be susceptible to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). They can also transmit the virus both through direct and indirect contact to one another, researchers find. The research paper is available to be read online in the Journal of Virology.
