Rabies is a fatal disease, resulting in a 100% fatality rate once infected. It cannot be completely cured. The reason rabies leads to 100% mortality is that after the rabies virus infects the human body, it continuously ascends to the brain, where it proliferates extensively, destroying brain tissue and leading to brain function depletion, a condition that is untreatable. Therefore, in dealing with rabies, it is crucial to focus on prevention. If exposed to rabies, it is necessary to receive the rabies vaccine.
