Hyo-Jick Choi, a biomedical engineer and professor at the University of Alberta in Canada, says he has a potential solution: A mask that can kill harmful pathogens, rather than just block them. The secret ingredient is table salt.
Viruses and other pathogens travel either through the air; in droplets such as saliva or phlegm from coughing, sneezing, speaking, or breathing; or on surfaces.
"The coronavirus-carrying droplets, expelled from coughing, sneezing, speaking or breathing, can stay on the surface of the masks," Choi told Business Insider. "The biggest technical challenge of the current surgical mask and n95 respirator is that they cannot kill the virus sitting on their surface, which increases the chance of the contact transmission."
But when a virus-carrying droplet encounters a mask coated in Choi's salt solution, he says, it begins to absorb the salt. Then once the liquid evaporates, all that remains is the virus and the crystallized salt — which slices through the virus, neutralizing it.

...Interesting to see if this is developed further

The couple behind us has a little girl not more than 4yrs the grand parents have turned up every Sunday since lockdown because their out in their garden,Sunday just gone they were there again,then later on they had another guy with his 2 girls and they were not keeping their distance
The message there is all about social distancing ... don’t go socialising in parks / countryside etc ... yet yesterday there were around 40,000 ( forty THOUSAND) logged at a nearby beach !!
Seems to be mostly bad news from the U.S. and England these days unfortunately. Canada and Australia seem to be doing okay overall from what I can tell with a couple of particularly bad areas in each. If anyone had been well prepared they would at least have had 100% testing early on for all nursing homes and their employees.
Had trouble getting flour here and had to get a much bigger bag than normal.
We wont get back to normality for a very long time,the way I look at it take one day at a time,forget about plans six month down the line,I only go out shopping once a week never go out for a walk,get plenty of exercise walking up and down the stairs thankfully got a nice garden to relax and enjoy the plants in colour the birds that come and feed it's lifts your spirits
The head of WHO has apparently just stated that the worst is yet ahead of us and latest tests show that only 2 to 3% of populations have been infected by Covid 19 ana that’s even in heavily affected countries !!
