^from what i gathered with the little info we got about how the virus affects the hunter it sounds an awful lot like fireblight meets adrenaline.. you can't regenerate red health but your health doesn't drain.. when your health starts to dip low enough attack and stamina increases. i would guess that the effect on the monster is an adrenaline rush. picture a tigrex having contracted the virus and his half halved of third to what normally is and without the ability to recover the hunt ending faster.....uuuuntil the virus kicks in like adrenaline. sort of like a couple of mega potions or max, demon drug and mega dash all roled into one. that tigrex was down in the demo.. no sleep bubbles.. no indication of a k.o. just boom...down and then the virus kicks in and he was feral like he is when in rage mode... i'm not saying its like a zombie virus or something but a good shot of adrenaline can wake the under 8 min. dead in real life.. don't see why this virus couldn't.
