Startling report suggests COVID-19 may have first appeared in 2012

Now, a report on the website Independent Science News by researchers Jonathan Latham, and Allison Wilson suggests that the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes the coronavirus disease (COVID-19), may not have originated at a Wuhan wet market in 2019, but 1,000 miles away in 2012, in a Chinese mineshaft where workers fell ill with a mysterious, pneumonia-like illness after being exposed to bats.

Can the coronavirus SARS-CoV-2 be spread through frozen food?

It is well-known that the coronavirus disease (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), can spread through respiratory droplets when people sneeze, cough, or talk. Recent evidence has also shown that the virus can hang in the air for hours, hinting at the possibility of airborne transmission.

Scientists claim signs of lasting SARS-CoV-2 immunity

Questions have been raised by many health experts on whether being infected with SARS-CoV-2 brings lasting immunity. Now, scientists have uncovered signs of strong and lasting immunity in people who even had a mild illness of COVID-19.

Coronacept - A trap-and-destroy molecule against SARS-CoV-2

A new study published on the preprint server bioRxiv* in August 2020 reports a novel engineered molecule based on human and other mammalian orthologues of ACE2 fused with the Fc part of the antibody. This molecule interacts more tightly with the viral receptor-binding domain (RBD) to constitute a powerful immunoadhesin that targets the virus for destruction.

Targeting SARS-CoV-2 with off-the-shelf CAR-NK cells

The current COVID-19 pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continues to spread and cause disease and death in many countries even today. At present, there is no effective treatment. A recent study published on the preprint server bioRxiv in August 2020 reports the potential of a new class of drugs called CAR NK cells, which could be used off-the-shelf to treat this disease.

Potential inhibitors of SARS-CoV-2 identified

Now, a new study published on the preprint server bioRxiv in August 2020 reports the discovery of two inhibitors of the helicase enzyme, which is essential for viral replication and the most highly conserved non-structural coronavirus (CoV) protein.

ARDS may not be the primary lung iInjury in COVID-19

A new Italian study published on the preprint server medRxiv in August 2020 shows that this may not be an adequate explanation, since ARDS is a nonspecific diagnosis. Instead, they say, antemortem lung biopsy shows a “Covid pattern” of acute lung injury, which could guide the application of therapeutics.

Scientists reveal most likely order of COVID-19 symptoms

Now, a team of researchers at the University of Southern California (USC) has revealed the order of symptoms often experienced by those who infected with SARS-CoV-2. Knowing the order of the symptoms may help the patients seek medical help immediately. The research is published in the journal Frontiers in Public Health.

U.S. scientists to create coronavirus strain for human challenge trials

Now, a team of scientists in the United States plans to create a coronavirus strain that can be used for human challenge trials, a controversial type of study wherein health volunteers would be vaccinated and intentionally infected with the virus.

SARS-CoV-2 spike pocket is a putative target for antiviral design

In a methodologically rigorous study, researchers from the University of Oxford have recently shown how the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike glycoprotein harbors a lipid-binding pocket which modulates the stability of the prefusion trimer and provides conformational shielding from antibodies. Their findings are currently freely available on the bioRxiv* preprint server.

Number of in-person health care visits not linked to COVID-19 infection in pregnant patients

In the spring of 2020, as Massachusetts experienced a surge in COVID-19 cases in the Boston area, four area hospitals conducted universal testing among all pregnant patients at the time of admission for SARS-CoV-2, the virus that causes COVID-19.

COVID-19 virus acts as a 'sponge' to deplete specific host microRNAs

Why is the COVID-19 virus deadly, while many other coronaviruses are fairly innocuous and just cause colds?

Frequently used serology test may not detect SARS-CoV-2 antibodies, shows study

Two different types of detectable antibody responses in SARS-CoV-2 (COVID-19) tell very different stories and may indicate ways to enhance public health efforts against the disease, according to researchers at The University of Texas MD Anderson Cancer Center.

Gaiter face covering provides respiratory containment of exhaled droplets

Experts with the West Virginia University Center for Inhalation Toxicology found that – assuming it's a good fit - a gaiter will, despite recent reports, provide a respiratory containment of exhaled droplets comparable to a common over-the-ear cloth mask.

FDA grants emergency use authorization to Yale's SalivaDirect COVID-19 diagnostic test

Today, the U.S. Food and Drug Administration issued an emergency use authorization (EUA) to Yale School of Public Health for its SalivaDirect COVID-19 diagnostic test, which uses a new method of processing saliva samples when testing for COVID-19 infection.

Influenza-virus-based vaccine platform another viable option against SARS-CoV-2

In a novel proof of concept study, published on the bioRxiv preprint server, U.S. researchers used attenuated influenza viral particles that express severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) receptor-binding domain to induce neutralizing antibodies in mice – unveiling another viable vaccine candidate for preventing coronavirus disease (COVID-19).

COVID-19 pandemic as severe as 1918 influenza pandemic

A recent study published in the journal JAMA Network Open reveals that the excess death toll observed during the initial period of coronavirus disease 2019 (COVID-19) pandemic in New York City is comparable to that observed during the peak of the H1N1 influenza pandemic in 1918.

Preexisting drug shows promise as a weapon against SARS-CoV-2 virus

First appearing in late 2019 in Wuhan City, China, the SARS-CoV-2 virus continues to cause sickness and death across the globe.

Can SARS-CoV-2 die out without immunity?

As the COVID-19 pandemic continues to take thousands of lives every day in different parts of the world, vaccine and antiviral research is continuing, as the only hope of emergence from under its shadow. However, a recent study by researcher Bhavin S Khatri at Imperial College London and published on the preprint server medRxiv* in August 2020 suggests that the pandemic may die out more rapidly than thought, provided the reproduction number is kept low.

COVID-19 during pregnancy shows no affect on placental structure and pathology

A new study published on the preprint server medRxiv in August 2020 shows that the placenta in pregnant women infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) does not show any signs of abnormality that can be attributed to the infection.
