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.

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.

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.

Low indoor air humidity increases spread of SARS-CoV-2

The airborne transmission of the coronavirus SARS-CoV-2 via aerosol particles in indoor environment seems to be strongly influenced by relative humidity.

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.

Children play a larger role in the community spread of COVID-19 than previously thought

In the most comprehensive study of COVID-19 pediatric patients to date, Massachusetts General Hospital (MGH) and Mass General Hospital for Children (MGHfC) researchers provide critical data showing that children play a larger role in the community spread of COVID-19 than previously thought

COVID-19 linked to type 1 diabetes and diabetic ketoacidosis in children

A team of researchers at Imperial College Healthcare NHS Trust and Imperial College London has found a link between COVID-19 and new-onset type 1 diabetes in children. The research is published in the journal Diabetes Care.

SARS-CoV-2 hijacks antiviral factors to promote infection in human lung cells

Now, a new study published in the preprint server bioRxiv in August 2020 shows that under conditions resembling those in vivo, IFNs may promote efficient viral invasion instead.

Lab-on-a-chip technology detects COVID-19 antibody

A robust, low-cost imaging platform utilizing lab-on-a-chip technology created by University of California, Irvine scientists may be available for rapid coronavirus diagnostic and antibody testing throughout the nation by the end of the year.

New prototype device non-invasively detects COVID-19 in exhaled breath of infected patients

Few people who have undergone nasopharyngeal swabs for coronavirus testing would describe it as a pleasant experience.

Breast milk is not a potential source of infection, indicates study

As the novel coronavirus continues to spread around the world, so do the concerns of breastfeeding mothers.Although there have been no documented cases to date of an infant contracting COVID-19 as a result of consuming infected breast milk, the critical question of whether there is potential for this form of transmission remains.

Researchers identify mechanism that explains lower-quality immune response in COVID-19 patients

The release of massive amounts of proteins called cytokines can lead to some of the most severe symptoms of COVID-19.

Could the high rate of mutations bring about SARS-CoV-2's extinction in India?

A new study published on the preprint server bioRxiv in August 2020 shows the importance of uncovering the dynamics of the virus with particular attention to geographic variation.

Fresh and frozen food can harbor SARS-CoV-2 for at least 21 days

A recent study published on the preprint server bioRxiv in August 2020 suggests that foodborne contamination may underlie these outbreaks and that this route of transmission should not be overlooked to contain the pandemic.

Cytokine storms may prevent the development of long-term immunity to SARS-CoV-2

Shiv Pillai, MD, PhD, investigator in the Ragon Institute of MGH, MIT and Harvard and professor at Harvard Medical School (HMS), recently published a paper in Cell showing that that high levels of some cytokines seen in COVID-19 patients, as part of a cytokine storm, may prevent the development of long-term immunity to SARS-CoV-2, the virus that causes COVID-19.

Study reveals important trends in early COVID-19 patients in Massachusetts

Data from the first COVID-19 patients treated at three large Massachusetts hospitals reveal important trends, including disproportionate representation of vulnerable populations, high rates of disease-related complications, and the need for post-discharge, post-acute care and monitoring.
