The virus has entered into Adam’s nose pushing through his mucus further into the nasal cavity.
I really hope you don’t catch what I’m getting I’m sneezing all over the place and I’m starting to get cold.
Im not going to catch it I’m immune to everything!
A few days later...
Achoooo!
As Adam sleeps he sneezes multiple times allowing the virus’s particles to spread around the room and go into Amy’s nose. While the virus continues to infect Adam moving past his nose into his throat.
