I understand what you’re saying, but I do agree with them until it’s proven otherwise.
I believe they don’t consider it airborne, because normal exhalation does not send contaminated air around where anyone breathing that air could become infected..., that we know of. And I think that’s a reasoned belief for now. Absolutely nothing is in concrete as far as I am concerned though.
Fluids expelled would still have to enter the body trough a compromised skin area, not the lungs.
They have already admitted that someone with symptoms who sneezes or coughs can spread it to you if you are close enough and not wearing protective gear.
Especially small cuts, abrasions, your eyes etc.
Did you read the book, The Hot Zone? One of these threads had a link where you could read it for no cost. It was a very interesting book, and made me have a healthy respect for the value of adequate personal protection in dealing with the disease.
I think the doctors and health care workers who have been working on this outbreak are very brave and self sacrificing. I honestly don’t know how they can do it day after day.
