In your own source it is said unproven with detailed explanation:

>If we strip the above-displayed videos of their captions, we can take a look purely at what the videos show. In one case, it looks like a person was the victim of a traffic accident. In another, it appears that a man suffered a head injury. But since these videos appeared online during heightened hysteria about an outbreak of an illness, it’s easy to see how a passerby may have made the assumption that these incidents were connected to the coronavirus.

Folks, if you see someone collapse on the street and they're wearing a mask. TAKE THE MASK OFF OF THEM. They're not getting enough oxygen. It is taxing to breath through an N95 mask. Source: I passed out when I put on a surgical mask while my wife was getting an epidural. Not from seeing the needle because I didn't even see the needle, and I don't get squeamish anyway. I have low blood oxygen and it was too hard to breath through the mask.

Perhaps I'm selfish, but if I see someone wearing a mask and they collapse, the last thing I'm going to do is get near them...
