Once infected cells have sensed an invading pathogen, they secrete molecules called cytokines and chemokines. Cytokines such as interferons are molecules that signal neighbouring cells and induce an antiviral state in them. These cells are then primed to resist an infection with the invading virus.
Answer:
Direct transmission is the way something is transmitted directly, like a illness given to you by touch.
-----------------------------------------------------------------------------------------------------------
Example 1:
I got coronavirus through direct transmission when I hugged my infected friend.
-------------------------------------------------------------------------------------------------------------
Example 2:
When I had pink eye, I forgot to wash my hands after reaching to scratch my diseased eye, and held my sister's hand. She ended up getting pink eye too, because of the direct transmission.
