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.

BfR-Corona-Monitor: Many respondents have become more cautious about coronavirus

Starting this week, the new regulations for the containment of the coronavirus adopted by the Federal Government and the Länder will come into force throughout Germany.

Key populations need to be prioritized for early COVID-19 immunization in Canada

Canada's National Advisory Committee on Immunization (NACI) recommends vaccinating key populations, such as people at risk of severe illness or death, those at risk of transmitting the virus and essential workers, during the initial rollout of a COVID-19 vaccine in Canada.

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.

Study finds a subset of quick COVID-19 healers and antibody 'sustainers'

One of the pressing questions about COVID-19 remains: How long does immunity last? One key indicator of immunity is the presence of virus-specific antibodies.

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).

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.

Some of the main osteoporosis treatments could have a protective effect against COVID-19

Some of the principal treatments for osteoporosis, denosumab, zoledronate and calcium, could have a protective effect against COVID-19 in patients who take them, specifically a 30 to 40% reduction in the rate of infection, according to the results of a joint study by Hospital del Mar, the Hospital del Mar Medical Research Institute (IMIM), Pompeu Fabra University and the Pere Virgili Health Park.

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.

Primary care for acute health conditions declined dramatically since UK lockdown

Researchers have conducted a study showing substantial reductions in the number of people attending primary care services for key physical and mental health conditions in the UK since lockdown was introduced on March 23rd this year.

Eye's cornea can resist infection from novel coronavirus

New findings from researchers at Washington University School of Medicine in St. Louis suggest the eye's cornea can resist infection from the novel coronavirus.

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.

Review: One in five COVID-19 patients may only show gastrointestinal symptoms

Almost one in five patients with COVID-19 may only show gastrointestinal symptoms, according to a review of academic studies published in the journal Abdominal Radiology. The findings of the review suggest abdominal radiologists need to remain vigilant during the pandemic while imaging patients.

The best COVID warning system? Poop and pooled spit, says one Colorado school

Carol Wilusz's mornings now often start at 4 a.m., scanning the contents of undergraduates' feces. Specifically, scanning the data on how much coronavirus they flushed into the shadows, destined to be extracted from 17 manholes connected to dorm buildings on Colorado State University's Fort Collins campus.

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.
