Masks - Page 4

Two meters for well people.    Isolation if person displaying symptoms.

Aerosolized spray not just larger droplets from coughs and sneezes is considered very difficult to deal with for health professionals within the critical care setting.  

Critical patients on lower levels of aided breathing such as Cpap, Bipap expel copious amounts of aerosolized secretions.    

That’s one reason why so many full respirators are needed.  

To be honest as I’ve said in previous post we need to find ways to provide protection whether it’s bandanas, stitched fabric, or diving masks.  

ALL need frequent replacement and or very effective cleaning.   

Wash hands often.    Stay at home.   

Hi, quite right. I have only gained information by looking at differing expert & medical varying opinions. I have questioned the distances mentioned. ( I did rule out a vacuum "point"!), only vapour droplets in air (still or movement, breeze or waft etc). The point I was trying to make regarding such virus (mean distance aside). The virus does not exist (air-borne) unless suspended as I mentioned by expelling said droplets.The cleaning of apparel (masks, spectacles, gloves etc) should be discarded or cleaned, which is much of you were saying. As regard water. I was referring to vapour, ie steam & clouds (which seem to defy gravity)

Hi V,

I use a vaporiser for medical purposes. I can confirm that vapour does not sit in the air for 10 mins, it disperses in seconds, droplets are not vapour either  - I don't know who these people are making such claims, but we all know there's a lot of confusing information out there.  I do agree with caution and not belittling anyone wish to offer helpful advice. But I am a reasonably intelligent individual and do understand some basic scientific facts, so forgive me for being a little sceptical about some points raised.

Business insider - the resource, is generally used for the financial markets and economy type reporting, so this is clearly an article they've referenced from somewhere else.

In the meantime, I did think the article posted up by by another helpful forum member - https://smartairfilters.com/en/blog/best-materials-make-diy-face-mask-virus/ on what you can use to make a mask if you don't have one, could prove useful for those who  need to go out shopping and do not have a surgical mask to hand.

We differ & we can explain both sides of the story, quoting vapour, quoting steam from a kettle or pressure-cook, aerosols etc (who in my experience I can confirm vapour does "sit" in the air.

Sir I have not timed "10 minutes" length from steam or from an aerosol. I too do not wish to belittle anyone, understand your scientific explanations. I am not talking about vapour, only the vapour which emanates from the human body, which may or not carry the virus.(see if you can see your breath on a cold day, just gently breathing out.)

As I clarified above both, expert & medical have varying opinions.

Advice in the Uk is that face masks have very limited effect as the vast majority of infection is caused by touching surface with the virus on them. The biggest thing you can do to protect yourself apart from isolation is to wash your hands after touching any surface. The danger from other people is expressed as exposure closer than 2m for 20 minutes. Essentially all that a mask will do is stop you sneezing a percentage of your germs onto surfaces. In the NHS  practitioners use special masks that need to be fit tested.....i.e. any tiny gaps will allow free flow of air.

The biggest ecconomic boost in this crisis is for mask manufactureres because people believe they ill keep them from the virus.

I agree, as a retired nurse standard hospital masks only protect the wearer for 2 minutes in normal circumstances. Builders masks only prevent breathing in dust & don't  give protection against infection. Unfortunately our local Guardia insist we wear masks & gloves even when taking the dogs out to have their toilet breaks & have chased walkers when in a very quiet area in our village orange groves! They insist anyone outside has masks & gloves on making getting to the local shop a nightmare for us in a small village where very few people have either! 

good on ya ray, seanie

I heard somewhere on Spanish TV ( Cinque o RTVE) that the forces of law and order may be spreading the virus involuntarily by asking for and then handling peoples documents without changing their gloves and sterilising their hands between each person that they check.

Correos, letters,paperwork, money or anything is touched has the potential to pass the virus. Hands to face, mask, spectacles. All potential. Therefore cleanse after touching anything. No other way forward.
