Player Character Virus Resistance
Similarly to a character's vitality value, a higher infection resistance value allows them to receive a greater number of attacks before succumbing to infection, NPC multipliers notwithstanding.
With the Nightmare scenario modifier enabled, certain enemy attacks such as grabs will deal twice their normal virus damage.
