Introduction
Dogs are one of the primary hosts of the rabies virus, and the virus may be present in their saliva and claws. When a dog scratches a human, especially causing a bleeding wound, the virus can potentially enter the body through the wound. Rabies is an acute infectious disease; once the virus enters the human body, it spreads along nerve fibers toward the central nervous system.
Generally speaking, getting a shot refers to receiving a rabies vaccine. If scratched by a dog and bleeding occurs, a rabies vaccine should be administered. If any discomfort arises, it is recommended to seek medical attention promptly. The specific analysis is as follows:
Dogs are among the primary hosts of the rabies virus, which may be present in their saliva and claws. When a dog scratches a person, especially causing a bleeding wound, the virus may enter the human body through the wound. Rabies is an acute infectious disease; once the virus enters the body, it spreads along nerve fibers toward the central nervous system, ultimately leading to severe neurological symptoms and even death. Therefore, prevention is crucial. Administering the rabies vaccine stimulates the body's immune system to produce antibodies, which can promptly neutralize the virus upon exposure, preventing further replication and spread, thus effectively protecting against rabies.
When interacting with pet dogs, one should maintain a safe distance and avoid being scratched or bitten.
