Researchers compare COVID-19 transmission risk when singing, speaking and breathing

Now, a new study* set to determine if singing and playing of woodwind and brass instruments produce more respiratory droplets and aerosols than speaking. Further, they want to know if the size and temperature of the venue will make a difference in the accumulation of aerosol droplets in the air.

Bioinformatics identifies key genes and cellular pathways in COVID-19

The COVID-19 pandemic is showing no signs of waning or extinction anytime soon. Now, a new study published on the preprint server bioRxiv* in August 2020 shows a new bioinformatics approach to studying the pathogenesis of this disease, by uncovering the differentially expressed genes (DEGs) and cell signaling pathways that cause the disease characteristics. This will help develop better therapies to counter the effects of these genes.

No evidence of active SARS-CoV-2 in breastmilk of infected women

A recent study published in the journal JAMA in August 2020 suggests that SARS-CoV-2 RNA does not represent replication-competent virus and that breast milk may not be a source of infection for infants.

Geographers conduct first daily surveillance of emerging COVID-19 hotspots

Over the course of the coronavirus epidemic, COVID-19 outbreaks have hit communities across the United States. As clusters of infection shift over time, local officials are forced into a whack-a-mole approach to allocating resources and enacting public health policies.

Influenza A virus can spread by airborne aerosolized fomites, finds study

Viruses like the influenza virus and even the novel coronavirus are capable of spreading from person to person via airborne droplets as well as dust, fibers, and other surfaces. Now, a new study provides evidence of airborne virus transport on microscopic particles called “aerosolized fomites.”

Study evaluates the reliability of new serological assays for detecting SARS-CoV-2 antibodies

Approximately four months after the initial description of cases of atypical pneumonia in Wuhan, China, in December 2019, COVID-19 had become a major pandemic threat.

Websites selling home-based COVID-19 testing kits providing inadequate or misleading information

In the UK and US, many websites are selling direct to user self-sampling and testing kits to detect SARS-CoV-2. Recently, a cross-sectional observational study was carried out to check the completeness and accuracy of information provided by these websites.

Fewer rhinovirus infections in Philadelphia after COVID-19 stay-at-home orders

Philadelphia and its surrounding counties issued a series of "stay-at-home" orders on March 17, 2020 in an effort to curb the spread of COVID-19.

New SARS-CoV-2 vaccine effective in macaques

Researchers from the biotechnology company Novavax in Gaithersburg, Maryland, have developed a vaccine against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that successfully induces immunogenicity and protection against the virus in macaques.

COVID-19 could compromise key element of immune response

Researchers at the University of Melbourne have made the unsettling discovery that infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) might compromise the activation of the CD8+ T-cell responses that would usually ameliorate disease and drive recovery in cases of respiratory disease.

Post-mortem study of dead COVID-19 patients finds lung damage and blood clots

A new post-mortem study of patients who have died from COVID-19 found severe damage to the lungs and signs of blood clotting in major organs.

Whey protein from human breastmilk inhibits SARS-CoV-2 infection

Many scientists have reported the effects of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection on pregnancy and the virus has been detected in breastmilk. Now a new study published on the preprint server bioRxiv* in August 2020 shows that whey protein in human breastmilk efficiently prevents infection with SARS-CoV-2 as well as post-entry viral replication.

Study shows how increased resilience can reduce anxiety, depression during COVID-19 pandemic

When it comes to worrying about the COVID-19 pandemic, a new study demonstrates that people are more concerned about whether their family members could contract the virus or if they are unknowingly spreading the virus themselves than they are with contracting it.

Cells lining the nose are key entry point for coronavirus, shows study

Scientists at Johns Hopkins Medicine, experimenting with a small number of human cell samples, report that the "hook" of cells used by SARS-CoV-2 to latch onto and infect cells is up to 700 times more prevalent in the olfactory supporting cells lining the inside of the upper part of the nose than in the lining cells of the rest of the nose and windpipe that leads to the lungs.
