    glad you mentioned time windows for viral infections which almost demolishes the social distancing argument in enclosed places with queues - higher 'comfort distances' - more time weighed - high chance of catching covid if after CDC 15 minutes.

    We embarked on a very slippery slope when masks became obligatory. We live in a society where we take a risk anytime we leave our homes. Going from recommended to bullying people into wearing them did nothing to help whatever good they were trying to do.

      Can you see the air (oxygen) outside we all breathe? No
      And can you see the virus? No
      So if the virus is in the air (oxygen) then it's clear that both the air and virus cannot be seen because they're both invisible and since you're able to breathe through the mask then what makes anyone think that the virus isn't getting through your mask too. If it's invisible like the air?... if there even is a virus.
      Masks are a lie and it's about control and that's fact.

    I just want to know what % wearing a surgical mask reduces your change of COVID. Nobody seems to have done a simple study on this. You'd just need to get voluntary test subjects, divide them into mask-wearing and non-mask-wearing, and have a conversation with someone who is positive and infectious, then measure the incidence of COVID in group A vs. group B

    All staff in hospital that I visited during October 22 wore face masks, including all visitors..yet a doctor on a home visit during November 22 when asked by me why are you not wearing a face mask, declared while coughing, I'm not wearing one unless they (presumably the government) tell me to. And this attitude while visiting an elderly patient..was elderly patient vaccinated..well, doctor did not ask..although doctor added he'd been to a concert recently and no one there was wearing one soooo. Previous health visitors all wore masks except Mr Arrogant.. Is he right or wrong?

    would like to ask the following scenario. If standard blue surgical masks used in period of lockdown we effective nursing stroke patient with NG tubes in and receiving nebulisers via electric atomiser pumps in enclosed space. An outbreak occurred and staff. Following a new patient transferred to the ward. Staff had been providing care using standard ppe mask plastic apron as no identified risk. 24 to 48 hours after Virus started to diagnosed in patients on the ward. Staff became ill following this and one staff unfortunately died other became quite ill. The reason I bring this up is staff effected and left with long conditions were finished from work. Fell of financial cliff government /nhs says you could of caught it anywhere. In truth most staff travelled to work and back in own cars. Those who couldn’t work hung out to dry. Claps and echo without substance.

      @I Stand Erected: I don't care if you believe it, Erected, and you sound as though you have made up your mind and are standing firmly on that, however home made double layer tightly woven cotton masks have been estimated to be about 70% effective against viral transmission, including Sars CoV2. How? Because larger droplets that contain millions of viral particles will likely hit a mask and can help prevent these blobs from reaching a person's mucosa in the mouth and nose. The number of viral particles at time of exposure is what determines the severity of Illness (it is called the "innoculum"). No one is saying that cloth and paper masks are 100% effective and that if you wear one that you will never get sick. However, wearing one can greatly reduce your chances of becoming seriously ill. You are free to research this a little further- Stanford did a study, and there are others, which have shown masks to be certainly helpful. Be well, but please stop spreading misinformation.

      @@riskbites Basic physics is calling you out. Covid is not a particle (Edwards 2021 et al), but an aerosol. Aerosols are not able to be caught by PARTICLE filters, especially face masks. 99% of the covid virons that are emitted by monkeys in the Edwards study were emitted as an aerosol. Masks used in a medical clinical setting are used to prevent body fluids from getting in the mouths of the staff and to prevent bodily fluids of the staff from entering open wounds etc of the people being treated. Mask packaging even have printed on them that they do not prevent exposure to virii. The testing on masks physically glues the masks to the dummy, and when glued provide only a 3% reduction in risk. Engineering solutions start at a 90% reduction. I don't know what a "fitted N95 masks" are but I am assuming you mean ventilators. Even HEPA filters used in isolation rooms in hospitals are not guaranteed to filter out virons, so they use a negative pressure system to exhaust all air in the room to the outside of the building to ensure prevention of contamination. There is a lengthy history of engineered solutions since the outbreak of legionnaires disease in "sick buildings". I give this video a 1 out of 10 for the fancy cartoons drawn. I take the 1 away for the shocking use of propaganda promulgated by the medical industry that is vying for funding from communist China or medical supply and pharmaceutical companies. Masks do not provide a lowering of symptoms like a placebo does and are known to cause over 40 pathological diseases and over 20 psychological conditions when used inappropriately, why was there no mention of these in this video?
