Giver mundbind mening? Does a face mask make sense?

Virus er ekstremt små.

Er virus en golfbold, er hullerne en fodboldbane. If the virus is a golf ball, the holes are a soccer field.

Hele foråret meldte myndighederne forskelligt ud om mundbind og corona. Throughout the spring, the authorities made different announcements about masks and corona.

Der er ikke meget viden for, at en maske beskytter dig selv. There is little evidence that a mask protects you.

Det kan give en falsk tryghed at gå med maske. Wearing a mask can give a false sense of security.

Så skulle man have det på i offentlig transport. Then you'd have to wear it on public transportation.

Uanset om der var andre eller ej. Whether there were others or not.

Det gjorde man, fordi smittetrykket var stigende. This was done because the infection rate was increasing.

Bruger alle mundbind, forebygger det. Everyone wears a face mask, preventing it.

Lad os slå én ting fast: Mundbind som teknologi virker. Let's get one thing straight: face masks as a technology work.

Lægerne har brugt dem siden 1910 for at begrænse smitte med fx pest. Doctors have been using them since 1910 to limit the spread of diseases such as the plague.

Men det, man er uenige om, er, om det giver mening at gå med dem - But what they disagree on is whether it makes sense to wear them

- eller om det bare giver falsk tryghed. - or if it just gives you a false sense of security.

- Forstår du, hvis der er forvirring? - Vi er blevet klogere. - Do you understand if there's confusion? - We've become smarter.

Forskellige kilder har sagt forskellige ting om mundbind. Different sources have said different things about face masks.

Det har været svært. It's been difficult.

Mundbind er en del af virkeligheden, og jeg vil vide mere. Face masks are part of reality and I want to know more.

Jeg vil finde ud af, hvilke mundbind der virker - I want to find out which face masks work

- hvilke der er til gene, og hvilke der er dårlige. - which are annoying and which are bad.

- Goddag. Hvad laver I her? - Vi tester mundbind og masker. - Hello, hello, hello. What are you guys doing here? - We're testing masks and masks.

Force Technology må teste og certificere mundbind og masker. Force Technology may test and certify face masks and masks.

Her foregår en praktisk test af et personligt værnemiddel. This is a practical test of a personal protective equipment.

I kammeret er der salttåge. Hvis salt slipper ind i masken, kan det måles. In the chamber there is salt mist. If salt enters the mask, it can be measured.

De tester hundred forskellige mundbind om ugen. They test a hundred different masks a week.

Måske en tredjedel dumper. Maybe a third fail.

Et godt mundbind kan brugeren holde ud at have på - A good face mask is one that the user can stand to wear

- samtidig med, at det filtrerer brugerens udånding eller nys. - while filtering the user's exhaled breath or sneeze.

Jeg vil lige klarificere. Mundbind og masker er to forskellige ting. I want to clarify. Face masks and masks are two different things.

Ansigtsmasker beskytter den, der har den på mod at indånde farlige ting. Face masks protect the wearer from breathing in dangerous substances.

Det kan være slibestøv, partikler eller biologiske farer som virus. This could be grinding dust, particles or biological hazards such as viruses.

De er ikke behagelige at have på længe. They are not comfortable to wear for long.

Mundbind skal beskytte andre mod din udånding. Face masks should protect others from your exhaled breath.

De bruges af læger og kirurger, så deres patienter ikke bliver smittet. They are used by doctors and surgeons so their patients don't get infected.

Sundhedsstyrelsen anbefaler dem, hvis du er smittet måske uden at vide det. The Danish Health Authority recommends them if you are infected, perhaps without knowing it.

Så er der det her: Et stofmundbind eller en community mask. Then there's this: A cloth face mask or a community mask.

De er ulovlige at sælge som andet end beklædning - They are illegal to sell as anything other than clothing

- for de skal ikke leve op til krav om filtrering og materialekvalitet. - because they don't have to meet filtration and material quality requirements.

Lad os se, hvad laboratoriet siger. Let's see what the lab says.

De er til at have på. Det er vigtigt for at få folk til at gå med dem. They're wearable. That's important to get people to wear them.

For forbrugeren er det umuligt at se, om filtreringsevnen er der. For the consumer, it's impossible to see if the filtering ability is there.

Derfor stilles der krav. That's why there are requirements.

- Har I testet dem? - En del. - Have you tested them? - Quite a few.

Vi har testet dem efter kravene til mundbind og masker. We have tested them according to the requirements for face masks and masks.

Det har de selvfølgelig lidt svært ved at leve op til. Of course, they have a hard time living up to that.

Vi spurgte Sundhedsstyrelsen, om de anbefaler et produkt - We asked the Danish Health Authority if they recommend a product

- hvor det ikke er testet, om det virker. - where it has not been tested to see if it works.

Altså om dårlige mundbind giver en falsk tryghed. That is, whether bad masks give a false sense of security.

Vi har ikke fået svar. We have not received a response.

Det med dokumentation er aldrig sort/hvidt. Documentation is never black and white.

Engangsmundbind er veldokumenterede - Disposable face masks are well documented

- og stofmundbind har måske ikke den samme filtreringsgrad - - and fabric face masks may not have the same degree of filtration

- men det er alt andet lige bedre end intet mundbind. - but it's better than no face mask at all.

Men hvor meget bedre er det kontra det bøvl, det giver? But how much better is it versus the hassle?

Et norsk studie siger: A Norwegian study says:

I en situation med 1,9 nye tilfælde pr. 100.000 borgere pr. uge - In a situation with 1.9 new cases per 100,000 citizens per week

- vil 200.000 skulle bruge mundbind perfekt i en uge - - 200,000 will have to wear a face mask perfectly for a week

- for at forhindre ét nyt smittetilfælde. - to prevent one new case of infection.

Styrelsen siger, at mundbind er effektive, hvor afstand er svært. The agency says face masks are effective where distance is difficult.

Men hvorfor mundbind, når man ikke kan holde afstand? But why wear a face mask when you can't keep your distance?

Mundbind er ikke finmaskede nok til at fange virus alene. Face masks aren't fine-meshed enough to catch the virus on their own.

Virusser er virkeligt små, hvis de flyver alene. Viruses are really small if they fly on their own.

Men når man taler, hoster, nyser, kommer virus ud i små vanddråber. But when you talk, cough, sneeze, the virus comes out in tiny water droplets.

Dem skal mundbindet fange - The face mask must catch them.

- så det ikke ender med en sky af dråber med smitte. - so you don't end up with a cloud of infectious droplets.

Lad vise det med en kopi af et videnskabeligt forsøg. Let's show it with a copy of a scientific experiment.

Man ser, at selv stofmasker begrænser mængden af små dråber, der kommer ud. You can see that even fabric masks limit the amount of small droplets that come out.

Det er ikke lige så godt som mundbind og masker - It's not as good as face masks and masks

- men det er bedre end ingenting. - but it's better than nothing.

Forsøget tager dog ikke højde for, at man kan bruge mundbindet forkert. However, the study does not take into account the possibility of using the face mask incorrectly.

Man kan røre ved det. Man kan sætte det og vende det forkert. You can touch it. You can set it down and turn it upside down.

Det ser dumt ud ... It looks stupid...

Det ser elegant ud, fordi jeg har 20 års erfaring. It looks elegant because I have 20 years of experience.

... og forringer effekten. ... and degrades the effect.

Bruger man det helt forkert, kan det skade. If used incorrectly, it can cause damage.

Selv hvis du bruger det korrekt - Even if you use it correctly

- er det ikke bedre mod smitte end hygiejne og afstand. - it's not better against infection than hygiene and distance.

Effekten af et mundbind er måske det halve af en meters afstand. The effect of a face mask is perhaps half the distance of a meter.

Derfor kan det ikke erstatte en meter eller to. Therefore, it can't replace a meter or two.

Men lægger jeg det oveni at holde afstand - But if I add that on top of keeping my distance...

- får jeg ekstra beskyttelse, selvom det ikke er perfekt. - I get extra protection, even if it's not perfect.
