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 respiratory coronavirus infections, including infections from the flu virus and the severe acute re...

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, while in others, the disease can be fatal. However, the reasons for this diversity in symptoms are not ...

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 against the disease. The different vaccines have reported efficacies ranging from over 90% for mRNA v...

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 environment-friendly circular economy model. Polymer materials have become an essential part of modern life a...

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, strategies have involved severe restrictions on people’s movements and gatherings, social distancing, ...
