A seemingly healthy dog has a 20%-30% chance of carrying the virus in saliva, but it is not infected by itself.
If such a dog bites, the virus will enter the blood through the wound and make people sick.
If you have been bitten by a confirmed rabies, this person must be infected with the virus, there is no doubt about it.
Even dogs vaccinated with rabies vaccine are not necessarily virus-free, because the best vaccine at present can only achieve a successful prevention rate of about 85%, that is to say, 25 of the vaccinated 100 dogs are just unsuccessful, just like those who have not been vaccinated.
