Most SARS-CoV-2-infected individuals develop durable B cell-mediated immunity

Researchers from the Johns Hopkins University and The Johns Hopkins Bloomberg School of Public Health, Baltimore, Maryland, USA, investigated the durability of B cell immunity following SARS-CoV-2 infection and recovery in their recent work published on the preprint server medRxiv.

Evidence of robust and persistent antibodies against SARS-CoV-2

A team of researchers from the Icahn School of Medicine at Mount Sinai, New York, have worked in collaboration to try and answer one of the most baffling questions surrounding the coronavirus disease 19 (COVID-19) pandemic: do antibodies against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) last after a primary infection?

SARS-CoV-2 mutations becoming more contagious

A team of researchers working with Scott Wesley Long from Houston Methodist Hospital and colleagues from Texas, New York, and Illinois studied the patterns of genetic mutations of SARS CoV-2 and its impact on the second wave of infections worldwide.

SARS-CoV-2 T-cell immunity is retained for at least six months

Now, a new study published on the preprint server bioRxiv shows that functional SARS-CoV-2-specific T-cell responses are retained for six months following infection. However, the strength of this response depends on the clinical features of the primary infection.

SARS-CoV-2 attack rates among household contacts higher than among non-household contacts

Now, a team of researchers at the National Centre for Infectious Diseases in Singapore aimed to determine the transmission risk factors of SARS-CoV-2 among household and non-household contacts.

AI speech processing framework detects inaudible COVID-19 cough

Now, a team of researchers at the Massachusetts Institute of Technology (MIT) has found that asymptomatic people may differ from those who are healthy in the way they cough. The differences are inaudible to the human ear but can be detected by artificial intelligence (AI).

Researchers track the flight trajectory of airborne cough droplets

The ongoing COVID-19 pandemic has led many researchers to study airborne droplet transmission in different conditions and environments. The latest studies are starting to incorporate important aspects of fluid physics to deepen our understanding of viral transmission.

16 new lineages of SARS-CoV-2 emerge in South Africa despite lockdown

Published in a recent medRxiv* paper, researchers from South Africa, the United Kingdom, and Brazil found that these mutations in SARS-CoV-2 lineages are localized to South Africa. These unique strains, not found elsewhere in the world, are thought to have contributed around 42% to the country's total infection rate.

Adaptive evolution of human coronaviruses may necessitate frequent reformulation of vaccines

Researchers from the Vaccine and Infectious Disease Division at the Fred Hutchinson Cancer Research Center, USA, have revealed that adaptive evolution in the antigenic regions facilitates seasonal coronaviruses to escape the host immune responses and to cause recurrent infections.

Rapid generation of divergent synthetic antibodies against SARS-CoV-2 in a cell-free engineering platform

In a groundbreaking bioRxiv paper, a research group from the Massachusetts Institute of Technology (MIT), Harvard University and Howard Hughes Medical Institute in the US engineered antibodies against the receptor-binding domain (RBD) of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike glycoprotein by using a novel approach. In doing so, they also identified more than 800 predicted binder families.

Re-thinking advance care planning during COVID-19 pandemic

Researchers in the UK have warned that healthcare professionals and providers need to consider how Advance Care Planning (ACP) can be resourced and normalized as part of standard care during the current coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), ahead of recurrent or future waves.

Beta-blockers could be used to treat COVID-19, study finds

Beta-blockers could potentially be used to treat COVID-19, according to a new international study by Italian and Australian scientists.

Study estimates the proportion of COVID-19 deaths due to air pollution

Long-term exposure to air pollution generated by human activity is linked to about 27 per cent of COVID-19-related deaths in East Asia and 15 per cent mortality in South Asia and worldwide. These deaths could be largely prevented by adopting air quality regulations, says a new study.

New model uses people’s breathing rates to track virus-carrying droplets

How many virus particles you inhale and where they land within the respiratory tract can affect your chances of contracting COVID-19, according to assistant professor Saikat Basu of South Dakota State University's Department of Mechanical Engineering.

Remdesivir metabolite GS-441524 inhibits SARS CoV-2 in mouse model, finds study

This new study titled, "Remdesivir Metabolite GS-441524 Efficiently Inhibits SARS-CoV-2 Infection in Mouse Model," was released online as a preprint on the bioRxiv* server, prior to undergoing the peer-review process.

Study elucidates mechanisms behind protective farm effect on childhood asthma

Asthma impacts millions of children already at a young age. Children growing up on a farm have a lower risk of developing asthma than children not living on a farm.

Estonian researchers provide clues to control the aggressive nature of SARS-CoV-2

Recent study by Estonian researchers in University of Tartu explains how coronavirus is activated before attacking the cell and what could help to impede that.

Only 56 percent of people intend to have free flu vaccination in the U.K. amid COVID

Now, a team of researchers at Keele University and Public Health England aimed to determine how many residents in the U.K. intend to get flu shots amid the COVID-19 pandemic. The researchers found that 55.8 percent of people intended to have the vaccination.

Children with asthma having fewer attacks amid the coronavirus pandemic, study says

During the coronavirus disease (COVID-19) pandemic, an international team of researchers has found that children with asthma experienced fewer upper respiratory tract infections, emergency visits, fever episodes, asthma attacks, and hospital admissions compared with the previous year.

Global collaboration provides a COVID-19 disease map

A collaboration of researchers from 120 different institutes across 30 countries including France, Germany, Australia, Japan, USA, India, Turkey, Brazil, and Canada initiated an effort to develop a COVID-19 Disease Map - a collection of computational models and diagrams of molecular mechanisms implicated in COVID-19.
