RE:RE:RE:RE:RE:RE:Face Masks.... more common sense Sorry to tell you common sense does drive with science. The covid-19 virus have shown to stay alive (ie. effective) from 3 hours to 3+ days outside of the host, depending on the type of surface, temperature and humidity condition. Surely the water content of the liquid droplet can evaporate during those time period, leaving the covid19 virus not encased with anything. If the surface is not disturb or air draft blown by it, virus likely stay put and eventually die off. However, if the surface is in high traffic area or high air movement area, the virus can be lift back up above the surface. Studies have shown the virus stay put on the ground if there is no disturbance. IE it is low chance getting infected by covid19 by aerosol transmission BUT IT IS NOT NEVER.
By N95 specification, it can stop 95% of particles at .3 micron or bigger, however, the covi-19 virus is approximately 0.125 micron. Hence why WHO had said face mask is not effective against covid19 but WHO didn't clarify the reason nor helping the curb the covid19 outbreak. IMO face masks does work by preventing water droplets in the air and when talking, sneezing and coughing. So, WHO is disingenuous about face mask purpose. .

N95 Respirators
An N95 respirator is a respiratory protective device designed to achieve a very close facial fit and very efficient filtration of airborne particles.
The 'N95' designation means that when subjected to careful testing, the respirator blocks at least 95 percent of very small (0.3 micron) test particles. If properly fitted, the filtration capabilities of N95 respirators exceed those of face masks. However, even a properly fitted N95 respirator does not completely eliminate the risk of illness or death.

Shouldn't they be wearing NBC charcoal filtered gas masks instead? Are you telling me you are smarter on this topic than a medical doctor??

Use your common sense.
wheeloffortune wrote: You have zero common sense. Evaporation works through steam. The human body doesn't release steam (you've been watching too many cartoons). Respiratory droplets with COVID 19 on it are propelled through the air by air pressure from our lungs and fall to the ground like a cannon ball with a range of 6'. That's why the CDC recommends a social distance of 6 feet. It's not air borne like a fart--it doesn't move through the air like a fart.
RagingBull3 wrote: Ever hear of EVAPORATION !!! When some of those tiny water droplets carrying the Virus evaporate in the air, where do you think the virus is left? In the air. They are air borne!!!
You ever see how a humidifier works?? It shoots a mist of water in the air. It evaporates even before it hits the ground.
wheeloffortune wrote: Wrong. CDC says the virus is not airborne, it only exists on floating water droplets which is why the N95 is effective for that size of particle matter. When you cough or sneeze, the virus is released in water droplets--the virus doesn't float alone in air. On surfaces, it lives in bacteria up to 24 hours. It cannot survive alone. Concentration affecting life or death again is nonsense, as it can replicate really fast if the immune system doesn't respond properly. Where are you getting this from??
Preexisting conditions plays a large role whether you live or die. What they've found is the highest risk factor is morbid obesity, a BMI of 30+ or 40 lbs overweight because your lungs aren't large enough to handle the spread. Dr. Vuong's collegue in NY found 70% of patients who have no other preexisting conditions were hooked up to ventillators only had morbid obesity in common. His collegue in NY has patients in their 30s hooked up to ventilators with no other condition than morbid obesity, 40+ lbs overweight. It's not an old person virus. Watch this video explaining what COVID-19 is and how it can kill you from a Dr. Duc Vuong, a general surgeon from Texas who wrote 13 books. https://www.youtube.com/watch?v=4J0d59dd-qM
RagingBull3 wrote: are they 100% effective.... of course not. N95... I think means 95% only, and that for particular matter of a certain size. A virus is much smaller.
But it does provide some protection. Some is better than NONE. It can reduce the amount (concentration) of viruses entering your body. Concentration of initial infection probably plays a large role in how bad you get, if you live or die.
Face Mask best use probably is for the infected person to wear it. Stoping/reducing the spread at its source.
And since we don't know who's infected or not, best everyone wear a mask.
Some protection is better than none. Some prevention is better than none.
