According to the literature, the longest case is up to 10 years.

After human being bitten by rabies virus infected animals, the incubation period is asymptomatic and gradual. The clinical symptoms rarely occur within 20 days, and most cases only occur after 30 days or even 4-6 months. In the early stage of rabies, patients have low fever, headache, general laziness, nausea, irritability, fear and other symptoms.

In severe cases, the patient also has painful convulsions throughout the body, leading to dyspnea. Most rabies patients are conscious; However, there are also some patients with mental disorders, nonsense. About two or three days after the exciting period, the patient becomes quiet, but then he becomes paralyzed, his respiratory and blood circulation system will fail, and he will quickly fall into a coma.
