A bleeding hamster bite usually requires prompt cleaning of the injury and vaccination. Hamsters are rodents and may carry hantavirus in their bodies. Often, hamsters need to be vaccinated against epidemic hemorrhagic fever before they are bred. After being bitten by a hamster and bleeding, the hamster’s body may carry bacteria and viruses that can be infected through the wound. At this time, it is important to disinfect the wound by rinsing it with running water or saline and applying disinfectant medication. After emergency treatment, you should go to the hospital in time for vaccination, usually need to be vaccinated with hemorrhagic fever vaccine, tetanus vaccine and tetanus antitoxin if necessary, and generally do not need to be vaccinated with rabies vaccine. After being bitten by a hamster, we should pay attention to it, and actively go to the hospital for diagnosis and treatment, so as to avoid causing diseases.
