How comorbidities affect SARS-CoV-2 viral entry

Almost from the start of the current COVID-19 pandemic, it has become clear that individuals suffering from other medical conditions like diabetes, cardiovascular disease, and lung disease are far more likely to contract the infection and to have a poorer outcome.

Face masks essential in combating asymptomatic spread of SARS-CoV-2 aerosols and droplets

The coronavirus disease (COVID-19) occurs through the transmission of droplets and aerosols from infected people through speaking, breathing, coughing, and sneezing. Wearing masks can reduce the airborne transmission of the novel coronavirus, a new study finds. The research is published in the journal Science.

Examining the envelope protein of SARS-CoV-2

A new study by researchers at the University of Valencia and published on the preprint online server bioRxiv in May 2020 reports the topology of the envelope protein of the virus, which could contribute to a better understanding of how the virus interacts with other cell components and hopefully help to fight the disease better.

Genomic variation and descent of SARS-CoV-2 strains in India

The pandemic of COVID-19 that is still affecting over 188 countries and territories the world over has taken over 359,000 lives in just under five months, while affecting at least 5.8 million people. Different strains have diverged from the original strain detected in Wuhan, China.

Ferritin heavy chain protein shows promise as a potential SARS-CoV-2 vaccine or antiviral

A new study published on the online preprint server bioRxiv in May 2020 reports the construction and testing of a new ferritin-based antigen-bearing protein that has biological activity towards the ACE2 receptor. This could indicate its potential for development as a vaccine or antiviral.

Research provides important insights into genetic adaptation of SARS-CoV-2 to humans

In their groundbreaking paper available on the preprint server medRxiv, University of Pittsburgh researchers were appraising signals of SARS-CoV-2 genome evolution and found that purifying selection (i.e., removal of deleterious mutations) represents the dominant trait during early coronavirus disease (COVID-19) pandemic - suggesting that the virus will evolve as it diversifies in a growing number of hosts.

Clinical trial of COVID-19 vaccine starts in Australia

Over 100 candidate vaccines are being explored as a means of ending the COVID-19 pandemic. Eight of these have already made it to clinical trials in humans, and another 94 are in the pre-clinical evaluation stage.

SARS-CoV-2 RNA in blood tests not associated with infectious virus

The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has challenged hospitals and laboratory services worldwide. Diagnostic testing for SARS-CoV-2 initially lagged but is now primarily based on the use of reverse transcriptase-polymerase chain reaction (RT-PCR) to detect viral nucleic RNA in the samples. However, viral RNA has also been reported in several small series of cases, though its significance and frequency remain unclear.

How India's lockdown has affected mental health

India’s public landscape has transformed dramatically over the last couple of months, with the most prolonged lockdown that the present generation can remember. Declared on March 24, 2020, the lockdown ensured that hundreds of millions of people were effectively confined to home, except when they ventured out, armed with a self-attested affidavit, to stock up on essentials.

Study shows children and adults have a comparable expression of SARS-CoV-2 entry-related genes

A recent paper by researchers from China demonstrated comparable expression levels of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) cell entry mediators in adults and children, suggesting that previously implied difference in viral-entry associated genes is likely not responsible for milder symptoms in children. The study is currently available on the medRxiv preprint server.

COVID-19 only kills 1% of people in remote Papuan village with limited resources

A researcher from Vrije Universiteit Amsterdam, The Netherlands, and a tropical medicine expert who lives in Wamena, Indonesia have published a unique account of a village in the Papuan highlands of Indonesia that has experienced what was presumed to be an outbreak of coronavirus disease 2019 (COVID-19)

Neurological complications of COVID-19: What is known so far?

Researchers at the São Leopoldo Mandic School of Medicine in Brazil have presented a review of the current data available on the neurological effects of coronavirus disease 2019 (COVID-9).

Mouse model mimics clinical course and pathology observed in COVID-19 patients

A mouse model of infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) reproduces features observed in human patients, researchers report May 26 in the journal Cell Host & Microbe.

CanSino's potential coronavirus vaccine triggers immune response in clinical trial

Scientists across the globe are racing to develop a vaccine that can provide protection against coronavirus disease (COVID-19). An effective and safe vaccine would curb not only the current coronavirus pandemic but also prevent future outbreaks

Blood clotting disorders may explain some of the worst symptoms of COVID-19

The hypothesis that blood clotting disorders may explain some of the worst symptoms of COVID-19, including respiratory failure and pulmonary fibrosis, was suggested in mid-April by researchers in Brazil affiliated with the University of São Paulo's Medical School (FM-USP) via an article accepted for publication by the Journal of Thrombosis.

What affects the case fatality rate of COVID-19? Analysis of top 50 affected countries

Ever since the beginning of the international spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that causes COVID-19 disease, researchers have been trying to identify the risk factors that increase the chances of infection. Now, a new study published on the preprint server medRxiv in May 2020 discusses various potential factors and reports the observed associations.

Many different T cell receptors recognize SARS-CoV-2 antigenic sites

The global COVID-19 pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is spreading over the world. However, not much is known about how the adaptive immune response kicks in following the viral challenge. This knowledge is crucial to predicting the efficacy of a vaccine and estimating the chances of reinfection.

Study finds very low level of SARS-CoV-2 in two San Francisco Bay areas

A new study published on the preprint server medRxiv in May 2020 reports a very low prevalence of antibodies in two separate populations living in the San Francisco Bay Area.

Heparin resistance among COVID-19 patients admitted to ICU

A new study has shown that COVID-19 patients admitted to the Intensive care unit may be resistant to the naturally occurring anticoagulant Heparin. The study titled, “Heparin resistance in COVID‑19 patients in the intensive care unit,” was published in the latest issue of the Journal of Thrombosis and Thrombolysis.
