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.

Should a COVID-19 vaccine be mandatory for children?

As the search for a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine continues, with some candidate vaccines nearing the completion Phase III clinical trials, a trio of experts weighs in with some sound reasoning as to whether any future vaccine should be considered mandatory for children. The viewpoint article is published in the journal JAMA Pediatrics in September 2020.

Study indicates factors that could have contributed to delayed detection of SARS-Cov-2 in the US, Europe

SARS-CoV-2 arrived in Washington State somewhere between late January and early February 2020, sparking rapid community transmission of the virus that went undetected for several weeks before this community spread became evident, prompting a change in testing criteria to emphasize individuals with no travel history.

Blood clots can be an early indication of COVID-19, shows study

A new paper by vascular surgeons at the University of Miami Miller School of Medicine, published in the Journal of Vascular Surgery, describes how thrombosis (blood clots in the circulatory system) was an early indication of infection in a COVID-19 patient.

Study compares clinical features of COVID-19 and seasonal influenza in children

As the fall approaches, pediatric hospitals will start seeing children with seasonal influenza A and B. At the same time, COVID-19 will be co-circulating in communities with the flu and other respiratory viruses, making it more difficult to identify and prevent the novel coronavirus.

Scientists find new way to capture "live" images of immune cells inside the lungs

University of Calgary scientists have discovered how to capture "live" images of immune cells inside the lungs.

A better understanding of SARS-CoV-2 in children

Researchers at Duke University School of Medicine in Durham, North Carolina, have conducted a study showing that Hispanic ethnicity is associated with an increased risk of infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) among children.

Single-dose adenovirus-vectored vaccine protects mice against SARS-CoV-2

The researchers selected the human adenovirus type 5 on which to base their vaccine because this replication-defective vector had already been used in their Ebola vaccine, with an excellent safety and immunogenicity profile in a phase 1 trial. The current study aimed to produce a vaccine that could offer mucosal vaccination and enhanced protection against this respiratory virus.

New technique enables real-time observation of influenza A hemagglutinin during viral entry

Unlike living organisms, to avoid extinction, viruses need to hijack living host machineries to generate new viruses.

People may have a pre-existing immune response to COVID-19 thanks to common colds

Now, a new study shows that some people have immune responses against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes COVID-19, thanks to how the body reacted the last time it caught a cold. This means that even if a person has not been exposed to the novel coronavirus, the body has a memory of it and can trigger an immune response to fight the infection.

Iota-carrageenan from red seaweed inhibits SARS-CoV-2 in laboratory conditions

In a recent bioRxiv paper, a research group from the Marinomed Biotech biopharmaceutical company in Austria showed that a sulfated polysaccharide iota-carrageenan has the propensity to inhibit cell entry of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by using an in vitro neutralization assay.

Face masks do not lead to false sense of security, shows study

Existing limited evidence suggests that wearing face coverings to protect against COVID-19 does not lead to a false sense of security and is unlikely to increase the risk of infection through wearers foregoing other behaviours such as good hand hygiene, say researchers from the University of Cambridge and King's College London.

Researcher receives Outstanding Investigator Award for groundbreaking microvascular and circulation research

Sarah Yuan, MD, PhD, professor and chair of the Department of Molecular Pharmacology and Physiology at the USF Health Morsani College of Medicine, has received a highly competitive National Heart, Lung, and Blood Institute (NHLBI) Outstanding Investigator Award to continue breaking new ground in microvascular and circulation research.

BATM introduces three new diagnostic kits for COVID-19 and other respiratory illness

BATM, a leading provider of real-time technologies for networking solutions and medical laboratory systems, announces the launch of three new diagnostic kits to significantly advance the diagnosis of COVID-19 and other respiratory illnesses.

Scientists identify compounds that block replication of COVID-19 virus

As the death toll from the COVID-19 pandemic mounts, scientists worldwide continue their push to develop effective treatments and a vaccine for the highly contagious respiratory virus.

Genes associated with SARS-CoV-2 human lung cell infection

Now, a new study published on the preprint server bioRxiv in June 2020 attempts to make sense of this data to identify viral genes that are explicitly expressed in the cells infected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This could help reveal new therapeutic targets.
