While the virus probably can be spread through surfaces and hand to hand contact, I think we are overreacting to that aspect of it. These cases are probably very rare in comparison to just breathing the virus in. There are theories that it can spread through the protein receptors in the eyes, maybe if you stuck your fingers directly into you nose... for the most part it is an overcompensation for just staying away from people. Continuing washing hands is probably a good practice, but I doubt it will make significant strides in slowing down the virus.

There is no reliable data to suggest what you are saying. Because it's a new virus, and it wasn't recognized for some time, we don't have any way of knowing the actual rate of death per case, much less do we know how many have come in contact with it to say how many were exposed, and percentage of those who were subsequently affected. What we DO know is that the death rate continues to drop as more people are tested and on record.

And because people don't generally freak out about the flu, because we're used to it, there is likely a HIGH percentage of people who've gotten the flu, and never went to the doctor to report it. I've had it twice, both times I ended up relapsing, and I didn't go to the hospital either time. But with coronavirus hysteria? People get hot flashes and they are running to the doctor.

You just can't quantify these things without being able to take into account the massive contextual differences.
