A cheap and widely available asthma drug appears to significantly reduce the risk of people being hospitalised with Covid-19, if it is taken within the first week of developing symptoms, research suggests. If the results are confirmed by other ongoing studies, inhaled budesonide – which both stops people from getting worse and shortens the length of their illness – could become the first treatment in the early stages of infection. The Stoic...

Letters Dr Jonathan Fluxman responds to a report about a Covid coughing study and calls for urgent change ‘We now know that any movement of air in and out of the chest generates aerosols, and the greater the respiratory effort (like deep breathing and coughing), the greater the volume of aerosols released.’ Photograph: Getty ‘We now know that any movement of air in and out of the chest generates aerosols, and the greater the respiratory effort (like deep breathing and coughing), the greater the volume of aerosols released.’ Photograph: Getty Fri 5 Feb 2021 12.43 EST Last modified on F...

Researchers from Bristol found that coughing produces 10 times more infectious 'aerosol' particles compared to speaking or breathing.

NHS staff are at ‘far greater risk from coughing than working in ICU’ Luke O'Reilly The NHS has been urged to rethink staff safety after a new study found that Covid can linger in the air from patients' coughing. The study found that coughing generated 10 times more aerosols (tiny infectious particles that can be breathed into the lungs) than speaking or breathing, The Guardian reported. The research, conducted by the University of Bristol and North Bristol NHS trust, sheds light on why NHS staff are four times more likely to catch coronavirus than members of the public. ...

The risk of airborne transmission of COVID-19 away from intensive care settings is greater than previously believed, a study revealed as questions swirl over aerosols in Australia. The UK study found that coughing released up to 10 times more concentrated aerosols emissions than the mean concentration from speaking or breathing. "Cough remains a significant aerosol risk," warned the study from the University of Bristol, which has not yet been peer reviewed. It said that "cough appears to generate significant aerosols in a size range compatible with airborne transmission of SARS-CoV-2", me...
