There is a certain incubation period after rabies virus infection, and the likelihood of developing the disease after 3 months is generally very low. Clinically, most people develop the disease 1-3 months after being infected with the rabies virus, but the length of the incubation period varies depending on the differences in individual constitution, and a few people have a longer incubation period, developing the disease 1 year or even more than 10 years after being infected with the virus. Therefore, it is not possible to fully determine how long rabies will be fine without an attack. Rabies, also known as hydrophobia, is a zoonotic acute infectious disease, often characterized by fear of water, irritability, fear of light, excessive excitement and other symptoms. Rabies is a national class B infectious disease with an incubation period, the length of which is related to the wound site, the infected person’s physical condition and the depth of the wound. Most of the rabies virus infected people in 3 months onset, but there are about 1% of infected people, affected by personal constitution and other reasons, the incubation period can be up to one year or even more than 10 years. The disease has a 100% mortality rate after its onset. Therefore, once there is a risk of rabies infection, one should remove any sense of chance and treat the wound and inject rabies vaccine under the guidance of a doctor in a timely manner. After being infected by the rabies virus, you should receive rabies vaccination in a timely manner, in full dosage and throughout the entire course of the disease, to avoid delaying the condition, in order to prevent the disease from attacking and endangering your life.
