Rabies is an extremely deadly disease, with a 100% fatality rate once infected, so prevention is crucial. According to clinical and laboratory research, the majority of cases result from bites by rabid dogs who were not vaccinated against rabies. Additionally, there are cases resulting from bites or scratches by cats who were not vaccinated. In places like the United States and Europe, bat bites are relatively common. In rabies cases involving dogs and cats, their saliva contains a high concentration of the virus, making infection likely if one comes into contact with it. Proper prevention is essential.
