ACE2-TMPRSS2 profiling indicates tissue vulnerability to SARS-CoV-2 infection

A new study published in April 2020 on the preprint server bioRxiv reports that the different levels of susceptibility of various organs to viral attack by the SARS-CoV-2 virus causing the huge pandemic of COVID-19 sweeping around the world can be predicted from the level of expression of two molecules, the ACE2 receptor, and the TMPRSS2 protein.

Remdesivir prevents COVID-19 progression to severe pneumonia, animal study shows

A team of scientists at the National Institute of Allergy and Infectious Diseases, which is part of the U.S. National Institutes of Health, has tested the efficacy of remdesivir, a nucleotide analog prodrug with a broad antiviral activity, as a COVID-19 treatment.

Scientists unveil novel coronavirus variants in India

The global coronavirus disease COVID-19 pandemic is ravaging the world, affecting 185 countries and territories and infecting 2.4 million people. Now, a team of scientists aims to shed light on the variants of the novel coronavirus strains in India, showing how changes correspond to its transmission and how it causes disease.

Computer simulations yield promising vaccine candidate against SARS-CoV-2

In a recent study that appeared on a preprint server bioRxiv, scientists from India designed a multi-epitope peptide-based vaccine that predicted high immunogenic response in the population.

Scientists predict how the novel coronavirus spreads in a typical household

A team of scientists recently carried out a study on the transmissibility of the virus in households. Simply put, they’re trying to predict how the virus spreads in a typical family: if one person gets sick, how many others get sick? How sick? How long would it take the family to recover? These are the practical questions this study tries to answer.

Remdesivir drug stops novel coronavirus from replicating

Scientists from the University of Alberta have published findings that the antiviral drug remdesivir prevents replication of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by inhibiting RNA replication. The study, published in April 2020 in the Journal of Biological Chemistry, follows on the heels of earlier reports from the same lab in February, showing the drug's effectiveness against the related Middle East Respiratory Syndrome (MERS) virus.

Novel coronavirus can be airborne for 13 feet

The novel coronavirus can travel up to 13 feet or 4 meters from patients in hospital wards, a new study has found. This is twice the distance current guidelines recommend for social distancing.

The race is on for a coronavirus vaccine, 70 candidates, 3 at human trial stage

Amid the coronavirus disease (COVID-19) global pandemic that is infecting millions of people across the globe, hope sparks as the World Health Organization (WHO) reports that seventy vaccination trials for the novel coronavirus are underway, with three already at the human trial stage.

Stray dogs possible origin of COVID-19 pandemic

After tracing coronavirus signatures in different species, a new research article published in the journal Molecular Biology and Evolution shows that stray dogs (more specifically dog intestines) may have acted as the origin of current severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic.

How does COVID-19 attack the body?

The coronavirus disease (COVID-19) attacks the lungs, leading to pneumonia, and eventually, a cascade of serious complications. But how does COVID-19 kill? Is it the virus itself or the result of the person’s immune system response?

Novel coronavirus attacks and destroys T cells, just like HIV

The immune system has many components that work together in protecting the body from foreign invaders. One of the most important types of immune cells is T lymphocytes or T cells, a type of white blood cell that acts as the core of adaptive immunity, the system that modifies the immune response to specific pathogens.

Cats, ferrets more vulnerable to COVID-19 than dogs

A recent Chinese study published on the preprint server BioRxiv finds that cats and ferrets appear to be extremely vulnerable to the virus, but dogs, pigs, and poultry do not seem to contract it. As preprints, papers are not yet peer-reviewed, undergoing only basic scientific screening.

First detailed map of transcriptome and epitranscriptome for novel coronavirus (SARS-CoV-2)

A team of researchers has come out with the first detailed map of the transcriptome and epitranscriptome of the virulent SARS-CoV-2 that causes COVID-19 disease, the illness that has become a pandemic ravaging both developed and less developed countries of the world. The study, published in the journal Cell in April 2020, may assist in the development of new vaccines and therapeutics.

Recovered South Korean COVID-19 patients test positive again

Following the reports from different countries of patients recovered from coronavirus disease (COVID-19) but testing positive again during the control diagnostic appraisal, South Korea's Centers for Disease Control and Prevention (CDC) documents a similar occurrence in 51 patients.

Weekly COVID-19 fatality predictions from leading epidemiologists

While many developed and developing countries are reeling under the impact of the SARS-CoV-2 virus, which causes COVID-19 disease, preventive and therapeutic measures alike need more accurate forecasts of fatal and non-fatal events to achieve preparedness and ensure an optimal outcome. Now scientists at Imperial College, London, have come up with a new weekly forecast of the number of deaths due to coronavirus and the likely number of cases reported in countries where the virus is actively spreading.

Chinese newborns experienced mild form of COVID-19

A new paper published by Dr. Zhi-Jiang Zhang and colleagues from Wuhan University in the European Respiratory Journal in April 2020 reports that COVID-19 apparently left little impact on newborns born to infected mothers at the height of the epidemic.

Ai used to detect COVID-19 pneumonia

Coronaviruses have 'spilled over' to human populations throughout history, causing respiratory illnesses, often associated with pneumonia. The severe acute respiratory syndrome (SARS), which emerged in 2002 in China, and the Middle East Respiratory Syndrome (MERS), which was first seen in Saudi Arabia in 2012, are similar to the current global pandemic spreading worldwide, the coronavirus disease (COVID-19).
