The incubation period of rabies is generally 1-3 months, with a few patients developing the disease within 1 month or more than 1 year after infection, and in rare cases the longest incubation period can be more than 10 years. Rabies is caused when a person is scratched or bitten by a rabies-infected animal and the rabies virus invades the body through the broken skin or mucous membrane and expands along the nervous system toward the central nervous system. The incubation period is mostly 1-3 months, during which there are no obvious symptoms. After the virus reaches the central nervous system, it proliferates rapidly, and atypical symptoms such as fever, headache, malaise, and muscle aches appear in the early stages. During the excitement period, the infected person develops a tightening sensation in the throat when stimulated by sound and light, as well as symptoms such as excitement, profuse sweating, salivation, and fear of wind and water. During the paralytic phase, paralytic muscle paralysis occurs, and eventually death occurs due to asphyxiation from lack of oxygen. Rabies has a near 100% mortality rate and is primarily preventative. Prevention methods include vaccination of domesticated animals, avoidance of scratches and bites by animals, and timely injection of rabies vaccine after being bitten by diseased animals.
