Imaging exhaled breath to provide new insights into Covid-19 transmission

A new method for visualizing breath that is exhaled while someone is speaking or singing could provide important new insights into how diseases such as Covid-19 spread and the effectiveness of face masks. “Scientists believe the SARS-CoV-2 virus is primarily spread through respiratory droplets that can be carried in the breath or expelled through coughing or sneezing,” said Thomas Moore from…

Researchers explore coronavirus interactions with cells

Scientists from Würzburg and the US have charted the first global atlas of direct interactions between SARS-CoV-2 RNA and human host cells. This may provide a starting point for novel treatments. SARS-CoV-2 infections pose a global threat to human health and a formidable research challenge. One of the most urgent tasks is to gain a detailed understanding of the molecular interactions between the…

Covid sensor ring detects even subtle symptoms

A smart ring that generates continuous temperature data may foreshadow Covid-19, even in cases when infection is not suspected. The device, which may be a better illness indicator than a thermometer, could lead to earlier isolation and testing, curbing the spread of infectious diseases, according to a preliminary study led by UC San Francisco and UC San Diego.

Covid-19 a far more serious threat than seasonal influenza, confirms huge data set

Nearly twice as many people were admitted to hospital for Covid-19 at the height of the pandemic than were for influenza at the peak of the 2018/2019 flu season, a study of French national data published in The Lancet Respiratory Medicine journal has found (Covid-19, 89,530 patients vs influenza, 45,819 patients).

How SARS-CoV-2 benefits from helpers within the human body

Like all viruses, the novel coronavirus is dependent on help from the human host cell. Proteins are the functional units of the cell and enable the virus to enter the host cell or help the virus to replicate. Scientists from Charité – Universitätsmedizin Berlin and from the Berlin Institute of Health (BIH), along with colleagues from the United Kingdom, Germany and the United States, have…

Digital health tools to fight Covid-19

A great deal of solutions using new technologies have been released to help tackle the Covid-19 pandemic and a panel of international experts shared a few examples during the Barcelona Health Summit last October.

Covid-19 vaccine will probably be unavailable for many until 2022

Nearly a quarter of the world’s population may not have access to a covid-19 vaccine until at least 2022, warns a study published by The BMJ. A second study estimates that 3.7 billion adults worldwide are willing to have a covid-19 vaccine, highlighting the importance of designing fair and equitable strategies to ensure that supply can meet demand, especially in low and middle income countries.

AI test rules out Covid-19 diagnosis within one hour

An Artificial Intelligence test has been shown to be able to rapidly screen patients arriving in Emergency Departments for Covid-19, using clinical information routinely available within the first hour of coming to hospital. Results of the CURIAL study, published in The Lancet Digital Health, show that the AI test correctly predicted the Covid-19 status of 92.3% of patients coming to Emergency…

Covid-19: risk increased sevenfold for healthcare workers

Healthcare workers are 7 times as likely to have severe Covid-19 infection as those with other types of ‘non-essential’ jobs, finds research focusing on the first UK-wide lockdown. And those with jobs in the social care and transport sectors are twice as likely to do so, emphasising the need to ensure that essential (key) workers are adequately protected against the infection, say the…

Covid-19: Is CT more sensitive than PCR testing?

Covid-19 causes characteristic changes in lung tissue visible in CT scans and chest radiographs, known as “ground-glass” opacities. Imaging is now considered a valid alternative, possibly even superior to RT-PCR. ‘This sparked an international debate about the role of CT in the diagnostic work-up of Covid-19,’ said radiologist Professor Cornelia Schäfer-Prokop.
