Fauci responds to the creepy video that shows the coronavirus spreading...

  • The novel coronavirus can spread via droplets, aerosols and fomite. Face masks can reduce transmission in all of these cases.
  • A popular YouTube channel created a simple experiment that shows how many particles a person emits when speaking. Dr. Anthony Fauci has now responded to the results.
  • Droplets and aerosol transmission make the virus so dangerous if face masks and social distancing guidelines are not followed. This frightening experiment proves that everything happens in front of us but is invisible to the naked eye.

The novel coronavirus spreads in three ways, but they are all based on the same rationale. Viral particles must reach the nose, mouth, or eyes. At this point, they may be able to join cells to start replicating. Droplet, aerosol and fomite transmissions are possible with COVID-19, with agencies like the WHO and CDC emphasizing the first. Fomites refer to touching surfaces that may be contaminated to become infected. Meanwhile, droplets and aerosols are essentially the same thing. They are tiny particles that are invisible to the naked eye and may or may not contain water. The larger droplets of saliva are heavier and are drawn to the ground faster by gravity than aerosols, which linger longer in the air and can travel distances greater than 6 feet. By blocking penetration through the nose and mouse, face masks can prevent droplets, aerosols, and even the transmission of fomite.

A new video in slow motion shows exactly how dangerous droplets and aerosols really are. It’s identical to videos released a few months ago warning of the risk of airborne transmission and the importance of wearing face masks and other covers that can protect the person wearing the mask and those around them . The special thing about this high-tech demonstration is that Dr. Anthony Fauci commented on the results.

Droplets and aerosols are also expelled from the mouth while speaking, not just when sneezing and coughing. We would normally ignore them as they would not be dangerous to health. Droplets and aerosols spread colds, flu and other viruses, not just the novel coronavirus. But we are all “trained” to treat these conditions.

The YouTubers at The slow mo guys Set out to create pictures that illustrate exactly how the virus can spread via droplets and aerosols, with and without a mask. With a dark room and backlighting, the YouTubers shot 4K footage at 1,000 frames per second to slow the speed of the particles emerging from the mouth.

They analyzed coughs and sneezes, but also regular conversations. For the speaking part, they used a mask and recreated the experiment. The conclusions are exactly what you would expect from these experiments. Humans throw a lot of invisible particles out of our mouth and it looks gross. We don’t see them in normal life because they are so small. But these particles, especially the aerosols that take longer to deposit, can spread the virus indoors and sometimes even outdoors.

Fauci was a guest on the show, commenting on this simple experiment anyone could do as long as they had access to the correct equipment.

“I think what you just showed is – you know – a graphically beautiful demonstration of the importance of wearing masks and face coverings,” said the health professional. “Because, as the film now shows, you say the same thing,” One, two, three, four “and very little comes out of the masks,” added Fauci, referring to the part of the experiment where the subject’s face was covered with a cloth mask. As Fauci notes, there are still some particles that can leak out of the mask, but the amount is significantly reduced. Face masks do not provide 100% protection and infection is still possible. That is why other health measures are recommended in addition to masks. Social distancing is one of them and should be used concurrently with masks.

Remember, however, that there is an extra layer of protection when everyone wears a mask – particles escaping through an infected person’s mask can still be blocked by your mask. This is especially true if you are wearing a quality face mask such as an N95 or KN95 mask.

“We say, and I think graphical demonstrations like the one you just showed really confirm this. One of the reasons it’s so important to wear face covering is that we now know that around 40% to 45% of people who are infected have no symptoms, ”continued Fauci. “And yet they have viruses in the nasopharynx. And we know that a significant proportion of infections are transmitted by someone who has no symptoms. So people have an understandable, but incorrect, interpretation that the only way to transmit infection is by coughing and sneezing over someone. What they don’t appreciate is that when you speak, even when you don’t speak out loud, and when you sing, which is even worse than just speaking, those particles come out that can stay in the air for a period of time. Some of them fall to the ground, which is why we say, “Stay 6 feet away!” However, some of them are aerosolized and can hang in the air for some time. ”

“This is why it’s so important to wear face-covering,” noted Fauci, even in situations where people aren’t coughing or sneezing around you. Later in the interview, Fauci explains why the virus is so dangerous and what vaccine requirements must be met to fight the pandemic. The full clip follows below:

Chris Smith started writing about gadgets as a hobby and before he knew it he was sharing his views on technical matters with readers all over the world. Whenever he’s not writing about devices, he miserably doesn’t stay away from them, even though he tries desperately. But that’s not necessarily a bad thing.
