I wonder if in certain circumstances, it can infect tissue almost directly, without having to travel too far in the blood stream. Nasal and lung tissue is fairly accessible in a direct way. To that extent, it is almost external tissue like skin, without the barrier the skin has of dead skin tissue.

It's an interesting point to debate . . . sort of like having the virus present but being asymptomatic in a way
