gates must think he owns the CDC. meanwhile, the CDC did not mention the RCT studies that do not promote mask use
from the link below
A number of randomized controlled trials of masks have been performed and the results, in short, are disappointing. There are no studies (RCTs) proving that mask use by the general community will reduce the number of people who get infected.
In a small number of studies, chiefly involving health care workers, there was a small benefit in the mask wearing group but the authors generally caution against extrapolating their results to the community setting.
In a few studies the mask wearing groups actually did worse then the non-mask groups. In one study with cloth masks, the cloth mask group did so poorly compared to the control that the authors specifically recommend against cloth masks for health care workers.
The CDC actually funded some of these studies so it is outrageous that they fail to mention any RCTs in their own discussion of masks.
The National Institute of Medicine specifically states that medical masks were not designed to prevent infection of the wearer, and per literature reviews of studies using medical masks there is no evidence that they do. And per one of the reviews discussed here, there is also no evidence they actually prevent infections in the patients.
The World Health Organization published a report in 2019 that summarizes the available evidence on masks – the evidence indicates a lack of effectiveness in preventing transmission of influenza.
There are also some indications of possible negative effects from constant mask wearing. The first study looking at viral contamination on the outside surfaces of masks was only published in 2019 and there is little other research on this subject. In addition to the possibility of getting an infection from your own mask, researchers have found elevated CO2 inside masks (over the OSHA recommended limit) and long term mask users report greatly increased incidence of migraine headaches.
