None of the mutations currently documented in the SARS-CoV-2 virus appear to increase its transmissibility in humans, according to a study led by UCL researchers. The analysis of virus genomes from over 46,000 people with COVID-19 from 99 countries is published today in Nature Communications. First and corresponding author Dr Lucy van Dorp (UCL Genetics Institute) […]
Temperature checks not very effective in detecting COVID-19 infection in symptom screenings
Temperature and COVID-19 symptom checks like the ones used at schools and doctor’s offices have again proved inadequate for spotting coronavirus infections and preventing outbreaks. A study of Marine recruits found that despite these measures and strict quarantines before they started training, the recruits spread the virus to others even though hardly any of them […]
Study measures effectiveness of different face mask materials when coughing
A team of researchers have tested everything from t-shirts and socks to jeans and vacuum bags to determine what type of mask material is most effective at trapping the ultrafine particles which may contain viruses such as SARS-CoV-2, the virus which causes COVID-19. The researchers, from the University of Cambridge and Northwestern University, tested the […]
Vitamin D levels appear to play role in COVID-19 mortality rates
After studying global data from the novel coronavirus (COVID-19) pandemic, researchers have discovered a strong correlation between severe vitamin D deficiency and mortality rates. Led by Northwestern University, the research team conducted a statistical analysis of data from hospitals and clinics across China, France, Germany, Italy, Iran, South Korea, Spain, Switzerland, the United Kingdom (UK) […]
Mouthwashes could reduce the risk of coronavirus transmission, study shows
Sars-Cov-2 viruses can be inactivated using certain commercially available mouthwashes. This was demonstrated in cell culture experiments by virologists from Ruhr-Universität Bochum together with colleagues from Jena, Ulm, Duisburg-Essen, Nuremberg and Bremen. High viral loads can be detected in the oral cavity and throat of some Covid-19 patients. The use of mouthwashes that are effective […]
In cell studies, seaweed extract outperforms remdesivir in blocking COVID-19 virus
In a test of antiviral effectiveness against the virus that causes COVID-19, an extract from edible seaweeds substantially outperformed remdesivir, the current standard antiviral used to combat the disease. Heparin, a common blood thinner, and a heparin variant stripped of its anticoagulant properties, performed on par with remdesivir in inhibiting SARS-CoV-2 infection in mammalian cells. […]
Will Wearing a Mask Protect You Against Coronavirus?
Fear of coronavirus infection has led to a massive increase in sales of surgical face masks and respirators. While the evidence is conflicting, some studies suggest healthy people do limit their chances of infection if wearing a face mask, especially properly fitted N95 or N100 respirators. With 663,828 reported COVID-19 cases across 177 countries and territories as […]
Wuhan study shows lying face down improves breathing in severe COVID-19
In a new study of patients with severe COVID-19 (SARS-CoV-2) hospitalized on ventilators, researchers found that lying face down was better for the lungs. The research letter was published online in the American Thoracic Society’s American Journal of Respiratory and Critical Care Medicine. In “Lung Recruitability in SARS — CoV-2 Associated Acute Respiratory Distress Syndrome: A […]
Coronavirus spreads quickly and sometimes before people have symptoms, study finds
Infectious disease researchers at The University of Texas at Austin studying the novel coronavirus were able to identify how quickly the virus can spread, a factor that may help public health officials in their efforts at containment. They found that time between cases in a chain of transmission is less than a week and that […]
New coronavirus stable for hours on surfaces
The virus that causes coronavirus disease 2019 (COVID-19) is stable for several hours to days in aerosols and on surfaces, according to a new study from National Institutes of Health, CDC, UCLA and Princeton University scientists in The New England Journal of Medicine. The scientists found that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was detectable […]
