STUDY: Masks make no significant difference


A new study indicates there is no statistically significant difference when it comes to wearing a mask or not outside the home to prevent Covid-19 spread.

According to the study, 1.8% of participants with masks got coronavirus. That compares to 2.1% of participants without masks.

A recommendation to wear a surgical mask when outside the home among others did not reduce, at conventional levels of statistical significance, incident SARS-CoV-2 infection compared with no mask recommendation.

ACPJOURNALS Study

The study is from the Annals of Internal Medicine. It is titled:

“Effectiveness of Adding a Mask Recommendation to Other Public Health Measures to Prevent SARS-CoV-2 Infection in Danish Mask Wearers, A Randomized, Controlled Trial.”

  1. I think we have to be careful in drawing conclusions.

    My understanding is the study says, in our present climate, where nearly everyone is wearing a mask, it doesn’t matter for the healthy if they wear a mask.

    However if the sick and asymptomatic were not to wear masks, we don’t know if masks are useless.

  2. Yeah, trying to stop a virus (particularly an RNA based corona virus) is a little like trying to stop a sandstorm with a chain-link fence.

  3. The mask reduces the risk of being exposed to virus, but the important thing is that if you are having the virus you are less likely to transmit it.

  4. I think people should concentrate on improving their immunity instead of relying solely on outside mitigation strategies. There is so much you can do for yourself. Just working on things like Vit D, C, melatonin, better diet, losing weight, good sleep, exercise, being in nature- all attainable, a lot of it free.
    Doing these things alleviates much fear and gives you control over the situation. Also, if you look at all cause mortality stats in U.S. to give you perspective you will find that about 2.3. million people die in the U.S. each year. This averages out to around 230,000 people each month (stats from CDC). Cancer, heart disease, diabetes, obesity, etc (all comorbidities for Covid-19) are listed.. The total number of Covid-19 now? 275,00 deaths in 9 months? How many would have occurred normally? What can you work on now for your immunity?

  5. If this true than how do you explain that republicans are 4 times more likely to catch and die from COVID19 than democrats. I can’t believe that the virus is political.

    1. Who told you that? New York City, New Jersey. Massachusetts, Connecticut, and Michigan were hardest hit. Not exactly hotbeds of conservatism.

  6. Does this mean strictly outdoors? “Outside the home” is a big vague. Does it include inside grocery stores, for example, where people experience closer contact? I’m not surprised not wearing a mask in a part doesn’t spread it. I do it all the time. Can you clarify this, please?

  7. Over the years, study after study conclude that masks are ineffective against a virus and essentially act as a safety talisman. This year, on the other hand, these same results are condemned in the press and the Leftist politicians.
    Study after study shows that the Left ends up destroying what they control: science, governments, sports, journalism, education, etc.

  8. This study should be repeated. In an era where false studies are planted in medical journals to make political hay, repeating the same design in other countries s/b worth the trouble.

  9. That is not news, they were two virologists out of Michigan, high-level scientist, who produced evidence that a mask was not effective. They went on to reveal in their video that in fact, wearing a mask was a greater health risk than not wearing a mask. This is about “control.“ There is a whole world of sheep out there who have been conditioned to no longer have critical thinking skills and to rely on government to dictate their lives. I am not one of them!

  10. Obviously more peer review and study is needed here. If masks are useless then what does work or do we just wait for a vaccine?

    1. It’s a virus. There is no “work” with a virus; you get it.

      That’s why your immune system is so critical, and why wearing the face diaper is bad for your health, and your immune system.

        1. This is advocating for people to throw themselves into harms way just to try and have an argument against masks. Masks don’t help the wearer, they’re for the people around the wearer. It’s to prevent other people from potentially getting covid from you.
          While this seems annoying and like you shouldn’t have to wear one if you know you don’t have covid: almost 40% of people with covid don’t present symptoms. You could simply just not know. Also, if you don’t have covid, good on you, but what about other people who do? It is easier to commit to an action as a whole, and simply protect everyone than to get involved in some round-about process to avoid just wearing a simple piece of cloth.

    2. Earl,

      Do your own research. The masks havent worked from the beginning. The virus is actually small enough to go through the mask. Wearing nothing is safer than the mask. it allows you to breath with taking in less oxygen putting more strain on the body. This makes the body more susceptible to a weakened immune system. Take some vitamin d and go work out.

    3. If masks don’t work, the lockdowns don’t work, and there’s no vaccine, we might have to rely on the immune system that’s been in place for the entirety of human existence. That system is 99+% effective across the whole population. For the highest at risk group (75+yrs old) the survival rate is about 95%. The vaccines they tested on healthy younger volunteers are 90-94% effective with nasty side effects they’ve only begun to start cataloguing. Your choice, but I say eat good food, exercise a little bit, and enjoy whatever life is your to live. Death comes for us all some day.

    4. Nothing will work. It’s a virus and spreads just like influenza. Masks are useless. Even vaccines won’t stop all people from getting it. Every year millions of people get flu shots and still get the flu.

      1. Exactly!…are we gonna have to have a covid shot every year too? I don’t do a flu shot and probably won’t do a covid shot either…j/s

      2. But, the typical influenza vaccine is only 40-60% effective. So, infection in some of the cohort that was vaciafed is to. E expected.

      3. You’re absolutely right. So long as humans live in social communities, all parasitic life forms that depend on humans to survive, will find a path to infect them. The only known factor regarding viral transmission is the fact that it is the quantity of virus exposure (viral load) that has a direct relationship to the severity of the illness. A light exposure typically results in little to no symptoms while heavier exposure increases the likelihood of more severe illness. So avoidance of heavy exposure is the only proactive strategy. It is unreasonable to expect to control exposure but reasonable to control the amount of exposure. Masks are not the answer, but they do signal to everyone that the environment is ripe with virus and we need to limit our exposure to mitigate the risk.

        1. I’ve heard that too. Makes lots of sense. I remember in my animal health classes a million years ago the prof saying “A virus needs a host”….which means it’s not like a bacteria that can form a spore and live in the soil for years……I have to assume that might still be true……

      4. Ding Ding Ding

        We have a winner!

        However people willfully disregard this because the MASK gives them a (false) sense of SAFETY / SECURITY! The MSM has perpetuated this hoax for 9-10 months now and the washing of the brain has taken hold solidly.

        It will take months, years to undue the damage to individuals psyche.

    5. Having conducted peer review I wonder, what exactly do you expect others to find with the data that has been provided?
      Are you disputing the data or the results.
      Studies aren’t designed to appease conformation bias.

    6. Unless you are immune challenged, it doesn’t matter anyway. This virus is lethal to less than 1% of the people who contact it. When you consider the government incentives to increase the count it may not even be as deadly as the flu.

      Did you know that even with seat belts and air bags, people still die in auto accidents? Should I assume that you don’t drive?

    7. What does work? A working immune system. People with metabolic related diseases are the most vulnerable. If you’re vulnerable, stay home. Otherwise, quite being afraid of a virus with a 99% survival rate.

    8. As Hamilton said “A nation which can prefer disgrace to danger is prepared for a master and deserves one.

      Short interpretation: use your Creator given unalienable right to life and make your own decision how to protect it.

      I’m a retired atmospheric chemist and choose not to wear a mask for a myriad of reasons.

      I’m not a doctor, but ones I trust choose to be prophylactic with Trump’s first medicine. Works for me.

    9. DISTANCE WASHING REG. LOTS OF OUTDOOR AIR WALKING EXERCISE 80YRS OLD FEEL GREAT WORK AN D WALK EVERY DAY AFTER THE SPAINISH FLU DRS WROTE DO NOT GET SHUTUP IN ROOMS WITH OTHERS GET OUTSIDE EXERCISE BREATHE FRESH AIR AND GET EXERCISE I WILL ADD DO NOT LISTEN TO THOSE WHO WOULD LOCK US IN GET THE IDEA IF NOT WAKE UP
