Rabies virus in the incubation period is contagious. Once bitten or scratched by a sick dog, one should go to the hospital in time for relevant treatment to avoid wound infection. Secondly, one must go to the hospital for rabies vaccination in time to prevent rabies infection. In general, the incubation period of human rabies is the period from exposure to the onset of the disease without any symptoms, usually one to three months, rarely as short as less than two weeks, and rarely as long as more than a year. Once the disease develops, it progresses very rapidly and can endanger the patient’s life within a few days. Therefore, it is recommended that patients must pay attention to it. It is recommended to keep a proper distance from pets, or to vaccinate them against rabies in advance. Keep the air ventilated and smooth to avoid the breeding of bacteria.
