There are many diseases that the origin of the ‘Vampire/Vampyr’ myth can be traced back to however I think rabies fits it the most.
In the olden days, people would tie those suspected of it to trees, in about three days time the disease would drastically change them. Extreme light sensitivity, paleness, aggression, excessive drooling. They could/would try to attack you and have bouts of either extreme slow fatigue or even adrenaline.
Also, Rabies can be passed form person to person through a bite, not just an infected animal.
