For those new to these threads, let me explain why the CDC (and some other health organizations) felt they had to lie about the aerosol nature of the disease.
There is an international shortage of masks of various kinds because they were needed in China. Those shortages mean that hospitals do not have as many masks as they need to protect their workers.
Therefore they are telling health care professionals to cover the patient’s face with a mask and to enter the room without a mask.
This will not work because the patient will have already contaminated the air in the room (including vents and other surfaces) and the health care worker will become exposed when they enter the room.
So, part of why this disease is so dangerous is that health care workers will get sick in large numbers and will not be available to assist the public.
The CDC decided to risk the health of health care workers rather than coming clean, because they did not want to cause a panic, and wanted to buy time to ramp up mask and other medical equipment production.
More details on how the patient contaminates their room even with the mask about halfway through the first video on the left:

(hint: think bathroom...)
The CDC is either
a) utterly, criminally incompetent
b) utterly, criminally trying to cause the US to crash as revenge on Trump
Choose either one or both.
