A common compound in mouthwashes found to inhibit SARS-CoV-2 in vitro Researchers found that cetylpyridinium chloride, found in most mouthwashes, lowers infectivity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in vitro, likely by inhibiting viral fusion with target cells. With more tests to prove validity, mouthwashes could be a simple, cheap way of curbing transmission. Studies in the past have shown that mouthwashes can have antiviral properties. They can decrease airborne...

SARS-CoV-2 antibody levels and types differ by disease severity, study finds Researchers have measured the antibody levels and types in hospitalized coronavirus disease 2019 (COVID-19) patients with different disease severity. Their results suggest gut immune pathways could play a role in reducing virus-based inflammation and recovery. COVID-19, the disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), affects people differently. Some patients are asymptomatic, whi...

Effective vaccine strategies for New South Wales Australia under different vaccine supply By modeling the effect of different vaccination scenarios, researchers say rapid mass immunization will terminate the disease, or immunizing 66% of the population with a 90% efficacy vaccine will achieve herd immunity. The approval of some vaccines recently against COVID-19, the pandemic disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), marks a turning point in the fight a...

In partnership with Neste, a leading producer of renewable fuels and feedstock for the chemical industry, Royal DSM aims to expand sustainable feedstock for polymer production and offer products that can support a more environme...

Quantifying SARS-CoV-2 transmission in large urban areas Researchers have developed a detailed model of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission in New York and Seattle, USA. They found the risk of transmission is a combination of the place and the behavior of people who visit it. Several strategies have been put in place to curb the transmission of COVID-19, the illness caused by the SARS-CoV-2 pathogen. As there are no effective pharmaceutical treatments, stra...

How does the UK’s COVID-19 response compare to others in Europe? Researchers modeled the health benefits and economic loss caused by coronavirus disease 2019 (COVID-19) in the UK and compared them to four other western European countries. Their results suggest the British Government’s response may outweigh the economic loss incurred. There have been more than 74.28 million confirmed cases and over 1.65 million deaths worldwide. The economic damage has also been severe, with the gross domest...

The company was established as a subsidiary of an automotive industry specialist Duracare to create safe and COVID-free areas with nanotechnology. Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) spreads when a person touches contaminated surfaces then directly touches their mouth, nose, or eyes. More than 68 million people have been infected wo...

Survey suggests COVID-19 vaccine hesitancy stems from a distrust in the vaccine development and approval process Survey results of COVID-19 vaccine hesitancy in Pennsylvania suggest that fewer people are likely to get the COVID-19 vaccine than the number of people who got the flu shot last year. Several countries have now granted approvals for vaccines to curb COVID-19, the disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). However, the vaccine will be truly eff...

Researchers use HACCP framework to assess COVID-19 transmission risks in universities Using the Hazard Analysis of Critical Control Points (HACCP) framework, researchers assessed the risk and mitigation strategies for universities with students returning to campus. The methodology allowed a rapid response to curb disease transmission with continuing education. The coronavirus disease 2019 (COVID-19) pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has disrup...

The effect of vaccination on the spread of COVID-19 disease Researchers from Cornell University, USA,  have modeled the effect of vaccination on the spread of COVID-19 disease. They suggest that vaccinating healthcare workers first followed by people who have many social interactions, such as grocers and airline cabin crew, will help reduce transmission. The research is published on the preprint server medRxiv*, prior to peer review. Vaccines have been an essential strategy in the fight again...
