I've read from many news and scientific sources that COVID spreads primarily through respiratory droplets, but I've also read multiple sources that have said we don't entirely know yet. Is it fomites, droplets, or aerosols? Is it some combination? Do we have a complete understanding of it?

With how infectious the B117 variant appears to be, it seems like it would spread through aerosols, since most other infectious diseases that are very contagious tend to spread through aerosols, like measles, tuberculosis and varicella. If that's the case, why do so many sources keep claiming that it's through droplets? I've also read an article on the Johns Hopkins website that suggested the scientific community was initially wrong about the mode of transmission for tuberculosis, so is that possible for COVID?

Thank you!

Please can you try edit your question to include links to where you found those statements (ideally primary sources). It'll improve the question and any potential answers. Thanks. $\endgroup$ – user438383 Jan 21 at 9:25
