One reason for the constantly changing information is that this virus is still very new to humankind. That's why it's called the "novel" coronavirus. The findings of the medical community keep changing because all we have to go on it what's happened so far. So the way things "seemed to be" a year ago, when the virus was just a few months old, would of course have to be different after millions have died from the disease, and many more millions were sickened by it. The medical and scientific researchers are learning all the time, and passing their findings along to us.
For instance, it was logical to think, at the beginning, that this disease was easily spread by touching surfaces (tables, countertops, doorknobs) that had the virus sitting on them. Recent research shows that that wasn't really true, it spreads almost entirely through the air, especially when propelled by sneezing, coughing, or yelling. So of course, masks are more effective than wearing gloves.
There seems to be an air of suspicion in some members of this forum, against scientists and others who are educated in this subject. I think some people have been indoctrinated to mistrust the findings of science and think there is a conspiracy out there to fool the public into believing what is not true, for some reason. But I think the answer is much simpler. We are all just learning, and our knowledge is incomplete. We do the best we can. Scientists are working very hard to seek answers, and I think the speed with which they came up with a vaccine is astonishing!
Interesting question, Asp, thanks for asking it.
