How quickly does rabies progress?
However, the virus typically takes at least 10 days—usually 30 to 50 days—to reach the brain (how long depends on the bite’s location). During that interval, measures can be taken to stop the virus and help prevent death. Rarely, rabies develops months or years after an animal bite.
What are the stages of rabies?

Why is rabies incubation period so long?
The Virus Travels through the Body
The time between the bite and the appearance of symptoms is called the incubation period and it may last for weeks to months. A bite by the animal during the incubation period does not carry a risk of rabies because the virus has not yet made it to the saliva.
Why do dogs die after humans bite?
Animals can only transmit rabies virus after it has reached the brain and started to spread outwards via nerves – it gets into saliva by working its way down nerves from the brain to the salivary glands. Once an animal gets to that stage of disease, they die quickly.
Can rabies spread through food?
It is unlikely that rabies will be transmitted through sharing food and water but if saliva from the infected patient came in contact with your mucous membranes (mouth), then this would be an exposure and you should seek treatment.
