Last, I'd like to point out that while I agree this type of virus is relatively new to humans, and the -2 virus is very new, we do have a wealth of longitudinal knowledge from SARS and MERS cases to work with in conjunction with what we are discovering about SARS-CoV-2. So far, it is not the patients with respiratory illness that we need to be concerned about. It is the patients with zero respiratory symptoms, but high risk of other cardiovascular and autoimmune symptoms. I think we're more baffled by how this one virus can go from putting someone on a ventilator to putting someone at a significant risk of stroke in such a short period of time.
That said, I agree with you that these are apples and oranges. The brain-eating amoebas are a panic thing. COVID-19 is not something to shake a fist at. COVID-19 has been found in spinal fluid. Given SARS and MERS do not share this trait, we have a lot more reason to take -2 as a serious threat, regardless of its extremely high short-term survival rate.
