A domesticated hamster bite through the skin needs to be vaccinated. A bite from a domesticated hamster may become infected. It is recommended to disinfect the skin immediately by rinsing it repeatedly with hydrogen peroxide or saline, and then applying iodophor or medical alcohol. If the bite is very serious, further treatment with debridement and suturing, and injection of tetanus antitoxin or tetanus immunoglobulin, or rabies vaccine is required. In addition, hamsters may have hantavirus, although the probability of domesticated hamsters being infected with this virus is very small, and if possible, they can be vaccinated against epidemic hemorrhagic fever. Once there is a high fever, headache, facial flushing, conjunctival congestion, etc., it is important to pay close attention to it and should be seen in a regular hospital in a timely manner. Patients who have been bitten by domesticated hamsters and broken the skin are recommended to go to the hospital in time for examination and standardized treatment under the guidance of the doctor.
