From what I've heard, humans just aren't terribly bitey. Seeing videos of kids with rabies is terribly sad, but does give some insight into it. More fear than anything else.

It's a terrible disease and a terrible way to die. If you get bitten or scratched by an animal, or even if you wake up to a bat in your house, you should immediately get the rabies vaccine, as even a microscratch from a bat can give you rabies. As far as diseases go, I'd say it's probably up there with ebola in terms of suffering. At least ebola kills you quickly even as your insides melt.

For one rabies is super rare in humans. When symptoms begin to show in humans they either die soon after or are sedated until they die. Some do rage, but again rare disease and quick death means you don't really get to see rage happening.

Uneducated Opinion: Because our higher brain functions can surpress fight/flight better than most animals. It’s the same reason jumpscare movies generally don’t turn theaters into a real-life bloodbath.

By the time rabies has gotten far enough to override that, the nervous system is basically gone and we’re dead.

I think it's because humans don't fight much with their mouths. We mostly fight with our arms and more rarely bite and rabies just promotes hyper aggressiveness, of which, these symptoms are exhibited in infected humans.

If restrained instead of sedated a human does get very aggressive, flailing their arms, screaming and hurling insults, even at loved ones and family members. I think given the opportunity there would be some biting, but less often than animals, because again, humans primarily use their arms for violence.

Humans rarely bite as a defensive option. Animals bite when they are scared, humans tend to throw punches.

Rabies doesn't make you bite, it makes you scared, confused and uncomfortable and aggressive, so you fight.

And:

... the generation of a “Zombie virus” cannot be firmly excluded according to the currently available biological evidence ... In keeping with this conjecture, an interesting simulation of an imaginary Zombie outbreak reveals that most of the US population would turn into Zombies within one week from appearance of the first case ... the transformation of Rabies virus into a “Zombie virus” will always remain a tangible threat surrounding human future

Humans don’t rely on instincts nearly as much as the typical animals you’d see infected with rabies. It’s pretty rare to hear of someone being injured by a human bite because we’re not made for that, other animals use teeth as a primary weapon.

The rabies virus wasn’t meant to transfer via humans, are just unfortunately affected by it because of similarities in biology
