Rabies can indeed cause fever during the more obvious period of clinical symptoms, often accompanied by excessive neurological excitation, such as drooling, tearing, sweating, and tachycardia. There may also be agitation, hallucinations, and other typical neurological symptoms such as hallucinations, convulsions, bizarre behavior, hyperfunction, and neck stiffness. These symptoms manifest as extreme fear, hydrophobia, fear of wind, difficulty swallowing, and high sensitivity to bright light and noise; most cases result in death within 3-5 days, and it is very rare for cases to last more than two weeks.
