Dus alle mannen binnen laten blijven, want daarbij is de kans veel groter dat het virus overgedragen wordt.
Daar is ook geen speld tussen te krijgen. Het ging er mij om dat je op tv pleit voor iets wat totaal niet haalbaar is. Er zijn niet genoeg mondkapjes voor de zorg. Laat staan voor kapsalons, nagelstudio's etc.
Daarnaast zijn er hier in ieder geval veel te veel kappers. Zou mij niets verbazen dat er via kapsalons en nagelstudio's in Nederland heel veel witgewassen wordt.

Ja wat is je punt? Nogmaals, het gaat er mij om dat er dus blijkbaar onderzoeken zijn waaruit blijkt dat het effect van mondkapjes niet bewezen is. Moet ik nu linkjes van die twitterberichten plaatsen?
En even voor de volledigheid, ik heb de wijsheid niet in pacht en ga ook niet doen alsof, blijkbaar zijn er allemaal wetenschappers en knappe koppen die er nog meer verstand van hebben dan wij en die niet op één lijn zitten.

Er is vrij veel kennis in Azie opgedaan met dergelijke pandemieen. Ze dragen vrijwel allemaal mondkapjes.

To help stop coronavirus, everyone should be wearing face masks. The science is clear

Do face masks protect against coronavirus? Here's what scientists know so far

That’s the worry I have after reading a paper by Roman Wölfel and colleagues, published this week in Nature. It shows that people are most infectious in the first week after catching Covid-19. During that time they often show no or few symptoms.
In other words, Covid-19 moves like a silent assassin, with unwitting accomplices. Maybe you’ll be one of them. The best way to ensure that you’re not: wear a mask, and keep your distance from others. Don’t wear an N95 respirator, the type in desperately short supply in hospitals, which is designed to keep doctors safe even when doing potentially dangerous medical procedures. But almost any kind of simple cloth covering over your mouth, such as a home-made mask, or even a bandanna, can stop the assassin in its tracks.
The Wölfel paper explains we must focus our efforts on stopping the spread of droplets. This is because the virus is primarily transmitted through tiny droplets of saliva ejected when we speak. You can’t see them, but they are there. We also know that these droplets can go significantly further than the 6ft which is widely cited as a safe distance.
Research supported by Nobel prize-winning virologist Harold Varmus tells us that placing a layer of cloth in front of a person’s face stops 99% of the droplets.
So, the science is clear. We do not know when we are sick. If we are sick, then when we speak we are projecting virus-laden droplets into the air. Wearing a simple cloth mask stops those droplets in their tracks. “I’m not going to wear a surgical mask, because clinicians need those,” said Dr Harvey Fineberg, chair of the National Academy of Sciences’ standing committee on emerging infectious diseases and 21st century health threats. “But I have a nice western-style bandanna I might wear. Or I have a balaclava. I have some pretty nice options.” Fineberg led a committee of experts that has just released an expert consultation explaining that the virus can spread through talking, or even breathing. Q&A How can I protect myself and others from the coronavirus outbreak?

Prof David Heymann CBE, a World Health Organization (WHO) adviser, said, “I think that wearing a mask is equally effective or more effective than distancing.”
In a paper published in Nature on Friday, a five-year study from the University of Hong Kong and the University of Maryland has found that a simple non-fitted mask blocked 100% of coronavirus droplets and aerosol. There’s a vast chasm between what the science is showing and what many countries are doing. Masks may be the most important weapon in our war on the virus. But we’re not even using it.
Worse, key leaders continue to lessen its importance. The WHO recommends only wearing a mask if you are sick, or looking after somebody who is sick. With the new evidence, this makes no sense, if it ever did. Many people who are infected don’t even know it. No wonder so many people are expressing such confusion about whether they should wear a mask.
Other key data offers even more proof. Every country with enforced mask usage shows dramatically lower death rates compared with countries not using masks widely.
We can also see dramatic results when a country changes its policy on masks. Masks were hard to come by in South Korea until late February. Then the government stepped in and ensured a supply for every person in the country. Up until then, South Korea showed a similar-shaped exponential trajectory to Italy. After that point the exponential growth slowed, and today the number of active cases is decreasing. There is no economic lockdown there.
Stanford economic policy research experts state that “the firm recommendation against masks in community settings appears incompatible with the available evidence”. Modeling by Yale researchers estimates that “the benefits of each additional cloth mask worn by the public are conservatively in the $3,000-$6,000 range due to their impact in slowing the spread of the virus”. A cloth mask is basically free, since you can make one from old T-shirts or sheets. So the economic payoff is hard to question. What other investment pays off by over 1,000 to 1?
One huge challenge is that mask wearing only really pays off when most people do it. A Food and Drug Administration analysis of the flu estimates that if 50% of the population uses a mask, virus transmission is reduced by half. If 80% of the population uses a mask, the virus is “essentially eliminated”.
That is why many jurisdictions have adopted laws that require mask use whenever in crowded places, such as public transport or shops. Some jurisdictions go further and require masks whenever out in public.
“Masks for All laws” are now in place in Israel, Austria, the Czech Republic, Hong Kong, Mongolia and elsewhere, with more locations added every day. In the United States, where these laws are taking a long time to appear, some counties are going it alone, including Laredo in Texas and Riverside county in California, which have created their own local mask use laws. New York and Texas haven’t yet used legislation, but their leadership have made a clear and direct plea to their communities to always wear a mask when in public.
These steps don’t replace the need for social distancing and hand-washing. We need to use the entire set of tools we have in our toolbox to stop this killer.
If we can’t rely on our governments to take this step, then we will have to take things into our own hands. We must rely on grassroots community efforts to get up to that magic 80% compliance number. We know this is possible, because the Czech Republic did it last month. In that country, a brilliantly effective social media and influencer campaign saw the country go from 0% mask use to nearly 100% mask use in three days. Then the government followed and made it the law.
Now it’s time for the rest of us to make this happen in our own communities.
That’s a marked difference from previous federal guidance that recommended only sick people or those caring for someone who is sick wear face masks. According to newly updated guidelines from the U.S. Centers for Disease Control and Prevention, anyone who is around other people should cover their mouth and nose with a cloth face cover, which the health agency says can be made from household items or common materials found at home. That, in turn, has raised questions about how people can best make their own face coverings at home, whether by sewing cloth masks or fashioning something out of bandanas or other fabric.
Wearing cloth face masks while in public can help prevent a person from potentially transmitting an infection to someone else. “If everybody wears a mask, it can prevent asymptomatic carriers from inadvertently infecting other people because it can trap the virus inside the mask,” says Dr. Larry Chu, a professor of anesthesiology at the Stanford University Medical Center. “That can help prevent the spread.”

Kunnen we allemaal ons voordeel mee doen, dus lijkt me een strak plan.
Duidelijk standpunt en het is je te prijzen.
Ook is het zo dat ik een patroon herken. Je ziet dat landen en instanties met meer pandemie ervaring eerder, meer en actiever mondkapjes promoten en/of gebruiken.
De laatste eckté pandemie in NL was in de eerste wereldoorlog die ervaring missen we hier een beetje. Overigens lijkt het er steeds meer op dat het standpunt van het RIVM niet persé onjuist is. Juist de individuele gebruiker heeft niet zoveel aan (niet-medische) mondkapjes. De groep heeft juist heel veel aan mondkapjes.
Mondkapjes die betrekkelijk makkelijk te maken zijn van kleding....

Dan ga je dat maar maken. Godsklere één van de rijkste landen ter wereld. Zet al die horeca-werklozen achter een naaimachine of verzin iets anders. Dat er te weinig (stoffen) mondkapjes zijn is een gebrek aan focus of zo je wilt aan ernstig falen.
Je regelt maar wat. Stoffenmondkapjes zijn géén hogere wiskunde (al zal JMD wel geen held zijn achter het naaimachine).
Kun je dat ook onderbouwen, in China en Singapore is er bijvoorbeeld geen verplichting om de straat op te gaan met een mondkapje.

Ja en dan ben ik ook erg benieuwd of er een patroon is dat die landen het beter doen met mondkapjes.

Hoor net dat een oud-collega van mij vrijdagavond is beboet. Ze hield met haar man een BBQ in de tuin en had twee bevriende stellen uitgenodigd. De sterke arm arriveerde en schreef zes boetes van 400 euro pp uit. Scheen dat die waren getipt door de buren.... Denk dat ze de komende vakantie daar niet voor de plantjes zal zorgen!

In Duitsland iig ( nog? ) niet. Daar is men het ook niet met elkaar eens. Er wordt dan ook volop gediscussieerd of die huisgemaakte mondkapjes wel voldoen en het goed signaal zijn.
Behalve die van Tankwart natuurlijk. Die zijn wel heel erg goed!:duim:
