Introduction
A dog bite without broken skin generally does not require rabies vaccination. When a dog bites but does not break the skin, it is difficult for the rabies virus to enter the body, although there remains a certain level of risk. Once infection occurs, the condition can deteriorate rapidly. It is recommended to closely monitor the wound; if symptoms such as fever, headache, or vomiting appear, seek medical attention promptly.
If bitten by a dog but without broken skin, rabies vaccination is generally not required. The specific analysis is as follows:
When bitten by a dog without skin breakage, the rabies virus has difficulty entering the body. The rabies virus is mainly transmitted through the saliva of dogs, and during a dog bite, the virus is primarily present in the dog's saliva. If the bite does not break the skin—meaning there is no wound or bleeding—the virus cannot easily enter the body. Therefore, in most cases, rabies vaccination is not necessary after a dog bite without skin damage. However, there remains some risk. Rabies is a fatal viral disease that progresses rapidly once infection occurs. Thus, even if the skin is unbroken, it is advisable to closely monitor the bite site. If symptoms such as fever, headache, or vomiting develop, medical attention should be sought immediately. Additionally, if the biting dog is a stray or suspected of having rabies, it is recommended to go to the hospital promptly for preventive rabies vaccination.
In summary, if bitten by a dog without broken skin, one should carefully observe any changes at the bite site and seek medical care promptly if any symptoms appear.
