I just don't get it. The overwelming data and studies show how effective masks are. If that wasnt the case (like Phuckitman said) why would surgeons, nurses and other hospital staff wear them or wear any PPE.
The reason the CDC changed course (which of course the video conveniently doesnt show) is that the original CDC guidance partly was based on what was thought to be low disease prevalence earlier in the pandemic. We all thought it couldnt spread to the EU and North America but that was not the case. What is worse and so concerning is both pre-symptomatic and asymptomatic transmission are possible – even common. Studies have found that viral load peaks in the days before symptoms begin and that speaking is enough to expel virus-carrying droplets.
Also remember, this video article is from a news pundit and is there to editorialize the news to push a narrative. That is very important for this typically is not found on your nightly 6pm news, they stick to facts.
