I think the virus prevents you from naturally recovering. (when you get damaged the red part of the bar slowly recoves, the virus stops that) I think you get an affinity boost if you damage the monster enough and get rid of the virus. I think for the monster, they just get stronger/faster as well as nmever losing stamima.

Yeah, I hope the ecology videos are still in. :c
