Are masks necessary to stop the spread of Covid-19?

A research done in 2010 (Cowling, B. et al.) about face masks and their effectiveness in preventing influenza transmission concluded that:

"...there remains a substantial gap in the scientific literature on the effectiveness of face masks to reduce transmission of influenza virus infection. While there is some experimental evidence that masks should be able to reduce infectiousness under controlled conditions, there is less evidence on whether this translates to effectiveness in natural settings. There is little evidence to support the effectiveness of face masks to reduce the risk of infection." Full study can be found here.

Another study from 2012 (Bin-Reza et al. (2012)) which examined different studies about masks and virus transmission found that:

"None of the studies we reviewed established a conclusive relationship between mask ⁄ respirator use and protection against influenza infection."
"...there is a limited evidence base to support the use of masks and/or respirators in healthcare or community settings. Mask use is best undertaken as part of a package of personal protection, especially including hand hygiene in both home and healthcare settings. Early initiation and correct and consistent wearing of masks/respirators may improve their effectiveness. However, this remains a major challenge – both in the context of a formal study and in everyday practice."
"There were 17 eligible studies … None of the studies established a conclusive relationship between mask/respirator use and protection against influenza infection." The study can be found here or here.

Is it political or pure science?

The CDC had a no-mask policy in place for more than 10 years. Here are the actions the CDC recommended in 2009 for interns to reduce the H!N! virus transmission:

1. Wash hands frequently with soap and water. If soap and water are not available, use an alcohol-based hand rub*
2. Cover your mouth and nose with a tissue when coughing or sneezing.
3. Avoid touching your eyes, nose and mouth
4. People who are sick with an influenza-like illness (ILI)...should stay at home

Note that the above does NOT mention wearing a mask. This sits well with Anthony Faucie's first remark about wearing masks outside, on March 8, 2020 in a CBS' "60 Minutes" interview:

"...Right now people should not be walking around with masks. When you are in the middle of an outbreak, wearing a mask might make people feel a little better and it might even block droplet but it is not providing the perfect protection that people think that it is... When you think masks you should think healthcare providers needing them." Here is the video of this segment and another video here.

Anthony Fauci retracted his initial statement, in an interview on June 12 2020, when asked by  "So, why weren't we told to wear masks in the beginning?":

"Well, the reason for that is that we were concerned the public health community, and many people were saying this, were concerned that it was at a time when personal protective equipment, including the N95 masks and the surgical masks, were in very short supply. And we wanted to make sure that the people namely, the health care workers, who were brave enough to put themselves in a harm way, to take care of people who you know were infected with the coronavirus and the danger of them getting infected."

So, in actuality, Fauci and his circle of decision takers told one thing to the American people while knowing it is not true. Some will call it a white lie and some will call it a blatant lie. Regardless of how people perceive this 180 degrees turn, we can assume that in the next time he has a big thing to announce it might not be what he is saying. Either as the big brother who knows better or the biggest advocate of the Pharmaceutical companies, which he has stakes in some, specifically the vaccine industry. Here is the link to his answer.

On April 27th the CDC recommended that ONLY people with Covid-19 symptoms should wear masks. Currently, July 2020, the CDC changed its policy and recommend everyone above the age of 2 years to put a mask on when being in a close proximity to people whom are not family members. To add to the confusion, the CDC itself recognizes that more research on cloth masks is needed to determine the efficiency of those masks. The CDC acknowledges a randomized controlled study that examined the efficacy of cloth masks in healthcare settings, where the result from this trial does NOT favor the use of cloth masks.

Face masks are not effective against Covid 19, by Dr Sherri Tenpenny, who is an American osteopathic medical doctor, researcher and author. She has invested 20 years, and over 40,000 hours, researching, documenting and exposing the complex issues of vaccine development, testing and distribution. As an internationally renowned speaker and author, her articles have been translated into over 12 languages.

Covid censorship about masks research:

Asymptomatic transmission of COVID-19 didn’t occur at all, study of 10 million finds Only 300 asymptomatic cases in the study of nearly 10 million were discovered, and none of those tested positive for COVID-19.

Anthony Fauci about Masks before he flipped his opinion/lie and before he recommended to wear goggles to protect the eyes from being an entry point for the virus.:

Mask might block a droplet- but its not providing the perfect protection that people think it is.

In an email from February 2020, Fauci states that asymptomatic people CANNOT spread the virus.
