Wow! So now it is officially announced that COVI19 can be transmitted via the air. Jeeez will wonders never cease!
Not exactly. But it is a best guess, tho, based on evidence. Pretty unethical to test this by purposefully putting people in a situation where they are exposed to airborne virus but not droplets.
And this is how science works, and sometimes doesn't work because of lack of data.
Putting all the anecdotal evidence and laboratory observations together it could well be that COVID can be airborne... but then maybe not survive for long. So, sometimes it appears it's definitely airborne, but then, not so much. It needs more testing... but we can't test it on humans ethically.
It is definitely in droplets. It can be passed by touch, but not as much as other viruses. Also, viral load until infection is unknown, making any of the vectors possibly worse or not as dangerous. Susceptibility may be affected by T-cells that 'remember' a previous coronavirus cold strain.. or not.
We still haven't gotten to the one year anniversary of the discovery of the virus. So much we don't know simply because we couldn't possibly know. All we have is the limited data we have and experience with other similar viruses. And COVID is turning out to be very unlike other viruses.
CDC almost always states things in terms of likelihood unless rigorous experimentation has given clear results. When people (whether the media or the general public) read CDC statements and then remove the "likelihood" language into definitive yes/no statements... then you get problems.
You also get problems when public policy is made based on "likelihood language" and people don't like the policy and so they attack the "likelihood language" as lies or incompetency.
The real incompetency is not reading the language carefully.
