Rabies becomes contagious when the virus reaches an infected animal's salivary glands, typically a few days before clinical symptoms appear (around 3-6 days for dogs/cats) and lasts until death, spreading through bites, scratches, or saliva on mucous membranes (eyes, nose, mouth). A person is contagious once they show symptoms, potentially for 5-28 days before death, though human-to-human spread is extremely rare, with rare documented cases from organ transplants.

What is the 10 day rule in rabies?

The 10-day observation period for a biting dog, cat, or ferret is a standard public health practice to determine rabies risk: if the animal remains healthy for 10 days after biting someone, it wasn't shedding the rabies virus in its saliva at the time of the bite, meaning the exposed person usually doesn't need rabies post-exposure shots (PEP). This quarantine ensures the animal is available for monitoring, preventing unnecessary euthanasia for brain testing and avoiding expensive PEP for the bite victim if the animal stays healthy.
 

At what stage can a dog transmit rabies?
