Genomic analysis provides clues about SARS-CoV-2 ancestry and transmission

Researchers in the UK conducting a genomic analysis of severe acute respiratory virus syndrome coronavirus 2 (SARS-CoV-2) and SARS-like coronaviruses in the bat and pangolin have identified strong host-associated divergences that could provide clues about the ancestry and interspecies transmission of SARS-CoV-2.

The American Lung Association say to wear masks to stop the spread of COVID-19; Here’s why

Dr. Albert Rizzo speaks to News-Medical about the importance of wearing masks to help control the spread of COVID-19.

Study: e-cigarette users have increased susceptibility to flu, COVID-19

In a controlled study of smokers, nonsmokers, and e-cigarette users, University of North Carolina School of Medicine researchers found that e-cigarette users exhibited significantly altered immune responses to a model of influenza virus infection, suggesting increased susceptibility to disease.

Children's DTP vaccine may provide cross-immunity for COVID-19

He found that the viruses subject to pediatric vaccinations do not have cross-reactive epitopes for SARS-CoV-2, showing they cannot provide protection against COVID-19.

Researchers use aerosolized molecules to shut down proteins generated by coronavirus

Researchers at Georgetown University Medical Center have successfully used molecules comprised of small strands of RNA to shut down the production of destructive proteins generated by the COVID-19 virus.

New strategy for designing COVID-19 antiviral drugs to inhibit key viral protein

SARS-CoV-2, the respiratory virus that causes COVID-19, attacks the body in multiple steps. Gaining entry into cells deep within the lungs and hijacking the human host cell's machinery to churn out copies of itself are two of the earliest steps -- both essential for viral infection.

Llama antibodies could be a potent nanoweapon against COVID-19

Today in Science, researchers at the University of Pittsburgh School of Medicine describe a new method to extract tiny but extremely powerful SARS-CoV-2 antibody fragments from llamas, which could be fashioned into inhalable therapeutics with the potential to prevent and treat COVID-19.

Research shows why certain people infected with COVID-19 show no symptoms

Researchers worldwide have been surprised to see that individuals can be infected with the SARS-CoV-2 virus - the virus that produces COVID-19 - without showing symptoms. Since these individuals expose others to infection without knowing it, it is important to find an explanation and hopefully a solution to this.

Mouth may be primary route of SARS-CoV-2 infection and transmission

A new study published on the preprint server medRxiv in October 2020 shows that the virus also multiplies robustly in the oral cavity, indicating that saliva plays a role in viral transmission.

Researchers develop lab-grown lung model to study SARS-CoV-2 infection

A team of Duke University researchers has developed a lab-grown living lung model that mimics the tiny air sacs of the lungs where coronavirus infection and serious lung damage take place.

COVID-19 containment measures affecting other seasonal respiratory viruses

A recent study published on the preprint server medRxiv* in October 2020 indicates that so far, the containment measures put in place to prevent the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have effectively prevented the transmission of many other respiratory viruses.

New article explores the endemic potential of COVID-19 virus

A new article by Columbia Mailman School researchers Jeffrey Shaman and Marta Galanti explores the potential for the COVID-19 virus to become endemic, a regular feature producing recurring outbreaks in humans.

Will COVID-19 become a seasonal virus?

In this interview, Dr. Hadi Yassine and Dr. Hassan Zaraket speak about their research into whether COVID-19 will become a seasonal virus.

A TLR2 agonist reduces SARS-CoV-2 in upper respiratory tract of ferret model

In a recent bioRxiv* preprint paper, Professor Miles W. Carroll et al. study an agonist for reducing the SARS-CoV-2's viral load. They show that prophylactic intra-nasal administration of TLR2/6 (toll-like receptor) agonist, INNA-051, reduces viral RNA in the nose and throat, in a ferret model.

Novel nasal treatment could protect people from COVID-19

A novel nasal treatment developed to boost the natural human immune system to fight common colds and flu, has proved remarkably successful in reducing COVID-19 viral replication test results, released today, reveal.

SARS-CoV-2 emergence linked with decrease in circulation of common respiratory viruses

Analysis of samples taken to test for respiratory viruses over the past five years suggests that the emergence of SARS-CoV-2 was associated with a large drop in circulation of other common respiratory viruses during the first wave.

AI used to define the cytokine storm implicated in fatal COVID-19

A new study published on the preprint server bioRxiv* in September 2020 reports the use of artificial intelligence (AI) to identify an invariant or universal host immune response found in all viral pandemics so far. The association of this response with severe COVID-19 phenotypes indicates a new understanding of the human immune response in viral pandemics.

Research explains why flu is dangerous for pregnant women

A team of researchers at the Royal Melbourne Institute of Technology (RMIT) University explains why flu can lead to potentially fatal complications during pregnancy, suggesting that the virus does not only stay in the respiratory tract but spreads throughout the body.

COVID-19 mitigation efforts significantly decrease influenza activity

The mitigation strategies implemented to curb the spread of COVID-19 appears to reduce the transmission of influenza in the United States, Australia, Chile, and South Africa. These strategies may augment influenza vaccines, especially for high-risk populations during the seasonal influenza transmission.

Different variants of SARS-CoV-2 identified in San Francisco Bay Area sewage

A team of scientists at the University of California, Berkeley, Innovative Genomics Institute, Illumina, Inc., and Stanford University has performed a genomic sequencing of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) collected from sewage in the San Francisco Bay Area.
