Sydney study about wearing masks

[tropical]

Re: Sydney study about wearing masks

"I have some questions:

Is it confirmed that surgical masks must be changed every time you come back home? "

WRONG, CHANGED EVERY TIME AFTER CHANGING THE EXPOSING ENVIRONMENT, at least yes but for such a virus the surgical mask is totaly UN-protective ...

"If you do not have the luxury of having 100 masks for yourself, is there any way to re-use them? Would bleach be a good idea? The masks are made of thin fabric... wouldn't getting them wet damage them?
Also, I read that influenza virus can typically only live 24 hours outside of the body, couldn't you simply put them aside (heat them in the microwave? or maybe leave them in the fridge?) and wait 1 day?"

If you want reinfect yourself from the outer side of the mask ...
100 pieces (1 a day, 3 months) of surgical have a very low price compared to the N95/100 ...

"Is it true, as tropical said, that the masks filter will only protect you from droplets from people sneezing, and not the smaller air-borne viruses from people coughing?"

If you want dig the literature to check now in the middle of an chimerized pandemic ... go on.

"And that brings me to my final question: how easily does it spread? Would a person have to cough or sneeze on you... or can the virus simply be floating in the air on an empty street, and you walk by and inhale it?

Current developments depict it as very infectious spreading.
Both can harm you if the air is full of pulvisculus with infectious droplets, but an empty street without direct infected air streams probably don't.

Without an sealed mask with a net under the micron, the best you can do is ducking at home.
