Unless the hamster is clearly known to have been bitten by an animal with rabies, rabies vaccination is not required, and tetanus vaccination is given if necessary. In general, the rabies virus is not contagious after being scratched by a hamster. Unless it is clearly known that the hamster has been bitten by an animal with rabies, the patient may not need rabies vaccination. However, because the hamster’s mouth contains a large number of bacteria, if the hamster bite bleeds, then this situation is likely to lead to redness, swelling, pus, or even necrosis of the wound. Get vaccinated against tetanus if necessary. A very small number of patients bitten by hamster may cause systemic bacteremia and sepsis manifestations, such as fever, general weakness, muscle joint pain and other manifestations. Therefore, although you may not need to be vaccinated after being bitten by a hamster, if you are bitten by a hamster, it is recommended that you go to the hospital as soon as possible, and under the guidance of the doctor to give the appropriate debridement, anti-infective and other treatments.
