What does rabies do to humans?
Following a bite, the rabies virus spreads by way of the nerve cells to the brain. Once in the brain, the virus multiplies rapidly. This activity causes severe inflammation of the brain and spinal cord after which the person deteriorates rapidly and dies.
Can a person survive rabies?
Once a rabies infection is established, there’s no effective treatment. Though a small number of people have survived rabies, the disease usually causes death. For that reason, if you think you’ve been exposed to rabies, you must get a series of shots to prevent the infection from taking hold.

How long can a human live with rabies?
If not, an infected person is expected to live only seven days after the appearance of symptoms. Rabies is transmitted through contact with the saliva of an infected animal.
Does water kill rabies virus?
The virus will not survive for long in water, but it will last long enough to possibly infect another animal. Rabies has an incubation period. The incubation is the period from exposure to rabies virus until the animal finally becomes sick or acts differently and is capable of infecting other animals or people.
What does a person with rabies look like?

What are the three stages of rabies?
Five general stages of rabies are recognized in humans: incubation, prodrome, acute neurologic period, coma, and death (or, very rarely, recovery) (Fig. 61-1). No specific antirabies agents are useful once clinical signs or symptoms develop.
Should I get tested for rabies?
