The Terrifying Way Rabies Works in Your Body

Rabies is an awful virus that doesn't work the way most viruses do. Once the symptoms start, it's fatal, and it's a particularly unpleasant death. You lose the ability to swallow, which is why the phrases "foaming at the mouth" and "hydrophobia" are associated with rabies. That's because the virus spreads through saliva, and successful viruses cause symptoms that enable them to spread to new hosts. The good news is that you can be vaccinated for rabies after exposure, and MinuteEarth will explain why that's so. 

You might think, well, why don't we just vaccinate everyone against rabies? My daughter is a veterinarian, and had to be vaccinated. It cost her $900. That's cheap compared to the cost of treatment after exposure. But for some reason, we can get our dogs and cats vaccinated for $30 or so. And that's turned out to be the best way to keep rabies under control in the modern world.
