Again, this is not a risk. You've already been told what ARE risks which to repeat are unprotected vaginal or anal intercourse (penetrating) or sharing of IV drug needles. Air inactivates the virus. Nothing has changed since the last time you posted.
Even if it is a bleeding cut, it is unlikely to pass through. Blood clots very quickly.
And every second the virus is outside a host, it slowly degrades.
Nope it doesnt. The virus cant just randomly penetrate the epithelial layer. It is like asking , can u walk through a wall?
