The rabies virus infects the central nervous system, ultimately causing disease in the brain and death. The early symptoms of rabies in people are similar to that of many other illnesses, including fever, headache, and general weakness or discomfort. As the disease progresses, more specific symptoms appear and may include insomnia, anxiety, confusion, slight or partial paralysis, excitation, hallucinations, agitation, hypersalivation (increase in saliva), difficulty swallowing, and hydrophobia (fear of water). Death usually occurs within days of the onset of these symptoms."
According to the New Jersey Department of Health, Infectious and Zoonotic Disease Program, "The majority of human rabies cases acquired in the United States are from bat exposures. However, all mammals are susceptible to all variants of the rabies virus."
