This is a very difficult time, and I do not envy the position the Bishops are in.
I suspect that if this disease were more like leprosy there would be no suspension. But the Wuhan coronavirus is much more contagious than leprosy, kills people faster than leprosy, and unlike leprosy can be transmitted before any symptoms are presented.
Given the extreme risk that the illness poses to others and the high likelihood of transmission, it seems to me that to forego reception of the Sacrament when ill with it would be an exercise of justice toward them in exactly the same way that one would be obligated to not attend Mass while sick with it.
Maybe I'm just speaking from a position of ease, but I think that if I was sick with this thing I'd forego the Sacrament and trust to the mercy of God, who knows how much I would desire it. I may have the right to receive the Sacraments, but I do not have the right to endanger the lives of others in order to do it.
