Is it a problem if bitten and bleeding by a golden hamster?
Generally, being bitten and drawn blood by a golden hamster carries a risk of infection. Prompt and proper wound treatment can reduce this risk, while inadequate care or insufficient immunity may lead to complications. If in doubt, it is advisable to seek medical advice promptly. The detailed analysis is as follows:

If the wound is immediately flushed with running water after the bite, disinfected with iodine or alcohol, and if tetanus vaccination has been received within the past 5–10 years without signs of infection such as redness, swelling, or pus, the risk is relatively low. In such cases, maintaining dryness and cleanliness of the wound afterward is sufficient, and the body can usually recover on its own.
However, if the wound is not cleaned and disinfected promptly, or if the wound is deep or shows symptoms of infection like redness, pain, or pus discharge, or if there is no history of tetanus vaccination or the last booster was over 10 years ago, there may be risks of bacterial infection or tetanus. In these situations, prompt medical attention is necessary to prevent worsening of the condition.
After being bitten and bleeding from a golden hamster, immediate cleaning and disinfection of the wound must not be neglected. Monitor the wound and your physical condition closely, and seek medical help promptly if any abnormalities occur. When keeping pets, take proper precautions to avoid further bites and ensure personal health and safety.
