Domestic cats can be asymptomatic carriers of SARS-CoV-2, show studies

Two recently published studies from Kansas State University researchers and collaborators have led to two important findings related to the COVID-19 pandemic: Domestic cats can be asymptomatic carriers of SARS-CoV-2, but pigs are unlikely to be significant carriers of the virus. SARS-CoV-2 is the coronavirus responsible for COVID-19.

SARS-CoV-2 deactivation on surfaces in 30 seconds with a copper paste

In a recent bioRxiv preprint paper, a team of researchers shows the possibility of using copper, in a new conformation, for effectively killing microbes immediately.

New understanding of glycan signatures of the SARS-COV-2 S1 spike protein

A team of scientists from the University of Oxford, UK, has revealed that site-specific glycosylation differs between spike proteins derived from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and a viral vector-based vaccine candidate.

Optimizing SARS-COV-2 inactivation for COVID-19 research at lower biosafety levels

Researchers at Montana State University have validated and compared two methods for inactivating the causative agent of coronavirus disease 2019 (COVID-19) that would enable the virus to be studied at a lower biosafety level (BSL) than the one currently required.

"Escape mutations" could help SARS-CoV-2 evade immune attack

Researchers in the United States have identified mutations within severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19) – that can reduce antibody binding to the virus, potentially mediating its escape from immune attack.

Examining potential foodborne transmission of SARS-CoV-2 through fresh produce

To address this gap in knowledge, researchers from the Bureau of Microbial Hazards, Health Canada, and Faculty of Medicine, University of Ottawa examined the survival of human coronaviruses on the surface of fresh produce such as apples, cucumbers, and tomatoes.

Vitamin D3 supplementation shows no therapeutic benefits in severe COVID-19 patients, study finds

A team of researchers at the University of São Paulo in Brazil aimed to determine if vitamin D3 supplementation reduces the length of stay in hospitalized patients with severe COVID-19.

Around 10 SARS-CoV-2 virions per cell in human body, study finds

A new study has found that there are about ten virus particles in each cell in the body. The research team from the Weizmann Institute of Science in Israel and the University of California in the USA estimate that each infected person carries around 109-1011 virions during peak infection.

Ancient East Asian peoples may have adapted to coronavirus-like epidemic up to 25,000 years ago

A new study by researchers at the University of Adelaide and Australian National University in Australia and the University of Arizona in the US shows that an ancient coronavirus-like epidemic drove the adaptation of East Asian peoples from 25,000 to 5,000 years ago.

How weather affects SARS-CoV-2 transmission: A US-based case study

How changes in the weather affect severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been the topic of several studies. The preoccupation of researchers with this aspect of the coronavirus disease 2019 (COVID-19) pandemic follows from observations that the flu virus and other coronaviruses follow seasonal patterns. Understanding how SARS-CoV-2’s transmissibility is affected by seasonal changes can thus help us to develop more informed preventative measures against its spread.

Around 30 percent of Australians hesitant to accept SARS-CoV-2 vaccine, study finds

A new study published on the preprint server medRxiv* in November 2020 suggests that a significant proportion of the Australian population is likely to show vaccine hesitancy. This indicates the need for public health messaging as well as, in some cases, other policy measures.

COVID-19 during pregnancy can cause placental inflammation and impaired immunity

A new study conducted by a team of researchers at Johns Hopkins University, USA, has observed how pregnant women infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) show stunted antiviral immune responses.

Severe COVID-19 complications linked to gut barrier breakdown

A new study claims that severe COVID-19 is caused by a positive feedback loop triggered by systemic inflammation and mediated by abnormal gut permeability. This finding could potentially help open up new avenues of treatment.

18 Nov 2020

SARS-CoV-2 causes a unique cytokine storm, study finds

A new study published on the preprint server medRxiv* in November 2020 reports some of the unique elements of COVID-19-induced CRS and how understanding these distinctive characteristics of the disease could help in formulating specific interventions and therapies.

COVID-19's harmful neurological effects are more common in patients with hypertension, diabetes

Some patients with COVID-19 are at higher risk of neurological complications like bleeding in the brain and stroke, according to a study being presented at the annual meeting of the Radiological Society of North America.

People with heart disease can receive high-dose or standard-dose flu vaccines for protection

People with heart disease can receive either the high-dose or standard-dose flu vaccines for protection from heart or lung-related deaths or hospitalizations, according to late breaking research presented today at the American Heart Association's Scientific Sessions 2020.

Children in Melbourne family developed COVID-19 immune response after exposure to virus

Children in a Melbourne family developed a COVID-19 immune response after chronic exposure to the SARS-CoV-2 virus from their parents, a new case report has found.

Aggressive COVID testing minimize the spread of disease among students

An aggressive COVID-19 surveillance and testing effort at Duke University was highly effective in minimizing the spread of the disease among students on campus, according to a case study appearing Tuesday in the CDC's Morbidity and Mortality Weekly Report.
