Masks work by reducing the spread of droplets. That means if you remove your mask by the cloth covering, instead of the ear loops or ties, you're getting potentially infected droplets on your hands and spreading them around. Remove your mask carefully by the ear loops, wash it after use, and wash your hands after removal. The easiest way to wash your masks might be to buy a week's worth and toss them into the washing machine with regular detergent. But I've also been soaking mine in my bathroom sink with hot water and no-rinse detergent, then line-drying in the sun.
Any form of cloth mouth cover, including a mask, can stop coronavirus spreading via invisible saliva droplets when an infected person talks, a study has found. Previous wisdom has said coughing or sneezing poses the highest chance of passing on the SARS-CoV-2 virus -- which causes the disease COVID-19 -- because they expel nasal or bronchial secretions, where the virus is known to be abundant. But coronavirus can also be spread in tiny speech droplets that are invisible to the naked eye, scientists from the National Institutes of Health in Maryland, US, claim. Speaking causes thousands of speech droplets to spray outwards every minute and scientist say it is likely this spreads the coronavirus. Writing in the study, the researchers say: 'Our results suggest that speaking can indeed be a major mode of SARS-CoV-2 transmission.'
Fox News senior judicial analyst Judge Andrew Napolitano weighs in. A new study suggests that homemade face masks with two or three layers may be more effective in preventing the spread of the novel coronavirus compared with a single-layered face covering. Researchers in Australia performed a video study comparing the effectiveness of different layers of cloth masks to surgical masks in their ability to stop the transmission of droplets in the air when speaking, coughing and sneezing. The study, which was published in the journal Thorax., found the effectiveness varied in the cloth masks based on the number of the layers. The single-layer masks reduced spreading droplets from speaking, but the double-layer face covering was better at preventing the spread of droplets from coughing and sneezing, the authors stated.
Wearing a cloth face mask while exercising leads to worse performance, according to the results of a small trial. It found that when donning a face covering, a person's exercise duration drops by 14 per cent while participants also recorded increased feelings of breathlessness and claustrophobia when exercising at higher intensities. The results of the trial on 31 healthy adults have been published online in the British Journal of Sports Medicine (BJSM). Thirty of the participants said that the task -- running on a treadmill to exhaustion -- was harder when wearing a face covering. World Health Organization (WHO) guidance backs up the finding, stating: 'People should NOT wear masks when exercising, as masks may reduce the ability to breathe comfortably'.
Officials hope the widespread wearing of face coverings will help slow the spread of the coronavirus. Scientists say the masks are intended more to protect other people, rather than the wearer, keeping saliva from possibly infecting strangers. But health officials say more can be done to protect essential workers. Dr. James Cherry, a UCLA infectious diseases expert, said supermarket cashiers and bus drivers who aren't otherwise protected from the public by plexiglass barriers should actually be wearing face shields. Face shields are more effective than masks in protecting the wearer from viral infection, Cherry said.
