A2.(1) Major historical error in 1910 became paradigm:
+ correct observation (ease of infection in close proximity) was misinterpreted as being due to ballistic droplets
+ Stated that aerosol infection was nearly impossible

A2(2) Unfortunately paradigm has reigned till today

For COVID-19, and other diseases, droplets are accepted w/o evidence. But aerosol evidence is NEVER enough

As stated by Chapin in 1910: aerosols very unlikely, the burden of proof is on their proponents

A2(3) The unquestioning proclamation of droplets as the main mode of transmission by @WHO and @CDCgov
is especially troubling, given that they have never been demonstrated to transmit any disease in the history of medicine

A2(4). Fierce resistance of aerosol trans. for 110 yrs led to only VERY contagious diseases (measles, chickenpox) being accepted as aerosol trans. Less contagious aerosol dis. not accepted

Leading to an artifact of history being confused w/ a law of nature

A2(5). The erroneous assumption that any aerosol-transmitted disease *has to be* extremely contagious leads to a lot of problems in health care, because "airborne precautions" are needed (scarce and expensive). Which leads to strong resistance
