We have several factors going on....."experts" all have opinions and many differ. When they are working on something new like C-19, they are forced to learn as they go.....and that will provide changing opinions. The public generally reads or hears and believes what they want to see or hear. The C-19 virus is not an exact science yet (hopefully we will learn enough to get it more exact), and thus difference of opinions, what seems to be misleading information, and unfortunately, social media generally throws in "misinformation". We will know the facts and more accurate causes and out comes some time in the future when C-19 is contained or wiped out and science will have enough accurate information to analyze.
