I’ve heard conflicting information on whether this virus is 85% or 99% similar genetically to SARS. If it is 99% similar, it suggests to me Novel Coronavirus mutated from SARS. (Facepalm).
I think the point was the patient in question was previously infected and although not completely immune, was still able to keep his virus infection in check. If this is what is actually going on, was it an earlier exposure and infection to SARS years ago or was it an infection, recovery, and reinfection with the Novel Coronavirus?
I agree with you. I don’t understand how this virus can be contained. However, it seems likely Summertime will be a major hinderance to this virus. I heard speculation, actually probably more like hope, that this virus will “Burn out” this Summer and not cause us any further problems.
