There was a rumor going around that members of the general public shouldn't ware face masks, implying they didn't help. Often this rumour was deliberately spread to discourage members of the public hoarding face masks because else such hoarding might prevent the people that need it most, like health care workers, from having them.
So do face masks really protect against catching C19?
The answer from the experts is simply is yes, despite them giving only limited protection. The message from the experts is that limited protection is certainly better than nothing because it really does significantly reduce your risk even though they very far from eliminates that risk and the experts warn that you shouldn't allow your face mask give you a false sense of security and think it would allow you to safely socialize with your friends for hours; That is another reason why that rumor was deliberately initially spread that you shouldn't ware them although they have generally stopped trying to do that more recently.
So the message from the experts is that face masks really are worth wearing. But as this video shows, it really helps to know a few extra things, such as how you should use those masks and what materials are the best ones if you make your own home made mask.
