Even if aerosols spread it which as you say is looking likely, masks will still help to contain SOME droplets, there doesn’t even need to be any research on this tbh it’s just common sense. Something over someone’s mouth and nose is going to catch some droplets. And on a whole population level, even a tiny amount can make a difference with infection control
There’s two ways I’m looking at this.
If COVID spreads only via droplets, then yes, source control may be a factor. So why not just ask those who are actively sick to wear a mask? Why mask the healthy?
If it’s spread via aerosols, then everyone would need to wear a tightly fitting N95 indoors, nothing less. Surgical masks that everyone wears are useless in those scenarios.
I’ve never understood the angst about wearing a mask in a shop or on a bus, for those who are able to
Probably that all vulnerable populations should be fully vaxxed by now? Just a guess.
So you say Japan still get slammed by flu, well how does that prove anything? Masks aren’t meant to eradicate a virus I thought, just help to control the numbers a tiny bit and help reduce viral load. So you could argue Japan’s flu numbers would be even higher without them. But there’s no way of knowing is there, again it’s just a common sense thing to do
Hard to prove a negative but people said that the reason that COVID didn’t kill so many in Asia was because of mask wearing. Well, it doesn’t work on seasonal flu ... which is less transmissible to start with?
Also, people are saying here that mask wearing made seasonal flu disappear worldwide in 2020, but it never made a discernible difference at any point in the past in Asia, so 🤷♀️
How nice that you lived in Japan, it’s like a different world isn’t it compared to here? There COVID handling has been pretty good too from what I’ve read, they don’t have the appalling death toll we have for a start
I don’t live in Japan anymore but you are dead wrong here. Japanese government dithered about, Japan never locked down (legally they can’t force businesses to shut down), there’s much less of a WFH culture so packed trains in cities ...
Conspiracy theory was going around that the Japanese government was somehow hiding deaths so they could have the Olympics that year, but it’s wasn’t true (no excess deaths)
You couldn’t even get a COVID test for love or money until very, very recently so cases tell you very little about the Japanese situation.
And now their vaccine rollout is a complete shambles.
I think you must mean South Korea 😂
