Should outdoor face covering be normalised to reduce transmission of SARS-CoV-2—or should anti-Covid efforts rather focus on indoor protection? Experts argue the case for both sides in this controversial debate.
Vigorous and rapid air exchanges might not always be a good thing when it comes to addressing levels of coronavirus particles in a multiroom building, according to a new modeling study. The study suggests that, in a multiroom building, rapid air exchanges can spread the virus rapidly from the source room into other rooms at high concentrations. Particle levels spike in adjacent rooms within 30…
New research by University of Texas at Dallas scientists could help solve a major challenge in the deployment of certain Covid-19 vaccines worldwide — the need for the vaccines to be kept at below-freezing temperatures during transport and storage. In a study published online in Nature Communications, the researchers demonstrate a new, inexpensive technique that generates crystalline…
Researchers at the University of Oxford report that the risk of the rare blood clotting known as cerebral venous thrombosis (CVT) following Covid-19 infection is around 100 times greater than normal, several times higher than it is post-vaccination or following influenza. The study authors, led by Professor Paul Harrison and Dr Maxime Taquet from Oxford University’s Department of Psychiatry and…
Any future attempts to reduce the spread of Covid-19 should be focused on tackling close airborne transmission of the virus which is considered to be the primary route for its circulation, according to experts. Respiratory experts argue that it is now clear that SARS-CoV-2 is most likely to transmit between people at close range through inhalation rather than through contact with surfaces or…
Researchers running the Com-Cov study, launched in February to investigate alternating doses of the Oxford-AstraZeneca vaccine and the Pfizer vaccine, announce that the programme will be extended to include the Moderna and Novavax vaccines in a new study.
Antimicrobial technologies such as coatings and textiles containing silver and copper are helping people during the Covid-19 pandemic by ensuring that whatever they touch, whether that is a door handle or their own mask, is free from live SARS-CoV-2 particles. But how exactly do these antimicrobial technologies work? How can a silver, copper or even polymeric coating kill microorganisms such as…
More than four in five (86%) people who were unsure or said no to a Covid-19 vaccine in December 2020 would now take one, or have already been vaccinated, finds the latest research by the Virus Watch study conducted by University College London (UCL).
Even as vaccines are becoming more readily available, protecting against the asymptomatic and pre-symptomatic spread of the virus (SARS-CoV-2) that causes Covid-19 is key to ending the pandemic, say two infectious disease experts at the Georgetown University Medical Center. In their Perspective, “SARS-CoV-2 Transmission Without Symptoms,” published in the journal Science, they make the case…
In what is believed to be the first published study of Covid-19 vaccine effectiveness in long-term care facilities such as nursing homes, a research team co-led by the Yale School of Public Health found a widely used vaccine is highly successful in preventing infections. Residents of such facilities, particularly those in skilled nursing facilities (SNFs), have experienced disproportionately high…
Miniature cameras which patients can swallow to get checked for cancer are being trialled across the NHS. The imaging technology, in a capsule no bigger than a pill, can provide a diagnosis within hours. Known as a colon capsule endoscopy, the cameras are the latest NHS innovation to help patients access cancer checks at home. Traditional endoscopies mean patients need to attend hospital and have…
Diphtheria – a relatively easily-preventable infection – is evolving to become resistant to a number of classes of antibiotics and in future could lead to vaccine escape, warn an international team of researchers from the UK and India. The researchers, led by scientists at the University of Cambridge, say that the impact of Covid-19 on diphtheria vaccination schedules, coupled with a rise in…
The European Commission has launched a contingency plan to meet the challenge of the various mutations of the coronavirus. Karolinska Institutet and Karolinska University Hospital are contributing to a new network for the evaluation and testing of new vaccines. The network is called "Vaccelerate" and it will contribute both to the evaluation of ongoing and future vaccinations, as well…
Research scientists at Aarhus University and Aarhus University Hospital have investigated the mechanisms by which hypertension leads to arterial damage and atherosclerosis. The results may facilitate the development of new therapies. Hypertension is a prevalent condition affecting approximately one third of all adults. It is also the leading global cause of morbidity and mortality. The condition…
A potential new treatment to protect immunosuppressed patients from human cytomegalovirus (HCMV) has been discovered by scientists at the University of Cambridge. Their study shows that certain epigenetic inhibitors expose and help to destroy dormant HCMV infections, which often reactivate to cause serious illness and death in these vulnerable groups. Subject to clinical trials, their proposed…
Preventing air contamination in healthcare facilities is crucial to minimise the airborne spread of Covid-19 and its new strains. Universal masking, rigorous use of and safe disposal of PPE, plus building ventilation are vital. Twenty-four studies reporting hospital SARS-CoV-2 air contamination are summarised in a meta-analysis by a multi-institutional team of French researchers. These show that,…
A team of researchers studying the effectiveness of different types of face masks has found that in order to provide the best protection against Covid-19, the fit of a mask is as important, or more important, than the material it is made of. The researchers, from the University of Cambridge, carried out a series of different fit tests, and found that when a high-performance mask – such as an…
Cardiovascular diseases are the most common cause of fatalities in Germany. Medical wearables which measure vital parameters such as the blood pressure, heart rate and blood oxygen levels in real time could help detect these diseases early, and treat them on a preventive basis. In daily life and during sports activities, in the form of fitness bracelets or smart watches, these small, portable…
Patients given preventive blood thinning drugs (prophylactic anticoagulants) within 24 hours of admission to hospital with Covid-19 are less likely to die compared with those who do not receive them, a new study finds. Clinical trials are now underway to see if prophylactic anticoagulants could be an effective treatment for Covid-19. In the meantime, the researchers say these findings provide…
Scientific and public health experts have been raising the alarm for decades, imploring public officials to prepare for the inevitability of a viral pandemic. Infectious epidemics seemingly as benign as "the flu" and as deadly as the Ebola virus provided ample warning, yet government officials seemed caught off guard and ill prepared for dealing with Covid-19.
People who are sceptical of getting vaccinated against infectious diseases may soon get a whole new perspective on things. Professor Robert Böhm and Associate Professor Guido Makransky from the Center for Social Data Science (SODAS) and the Department of Psychology at the University of Copenhagen have received DKK three million in funding from EIT Health for developing a virtual reality app to…
The first evidence from genetic data that high blood pressure is causally associated with the most common heart rhythm disorder is published in the European Journal of Preventive Cardiology, a journal of the European Society of Cardiology (ESC).
With Covid-19 dominating medical science and human concern, chemists at the University of Sydney have developed a method to quickly and safely synthesise protein vaccines for respiratory diseases for pre-clinical tests. Their approach can be used to test vaccine strategies against novel pandemic pathogens such as SARS-CoV-2, the virus that causes Covid-19.
Even those who understand the scientific process, trust medical experts and know how important vaccines are for fighting infectious diseases might still have some questions or concerns about the new Covid-19 vaccines. Here, Thaddeus Stappenbeck, MD, PhD, helps set the record straight on 8 common questions, concerns and myths that have emerged about Covid-19 vaccines.
Before the pandemic, the lab of Stanford University biochemist Peter S. Kim focused on developing vaccines for HIV, Ebola and pandemic influenza. But, within days of closing their campus lab space as part of Covid-19 precautions, they turned their attention to a vaccine for SARS-CoV-2, the virus that causes Covid-19. Although the coronavirus was outside the lab’s specific area of expertise,…
