Whether a chinchilla bite requires a vaccination depends on the specific circumstances of the wound and cannot be generalized. If the wound after being bitten by a chinchilla is not broken or is relatively shallow, the patient can heal quickly after cleaning and does not need to be injected, but needs to continue to observe the corresponding symptoms. If the wound is deeper and there is a risk of tetanus infection, tetanus vaccination is recommended. In addition, since chinchillas belong to small rodents, the probability of rabies infection is relatively low or even absent, so rabies vaccination is generally not required, but since the patient may be at risk of contracting hemorrhagic fever, epidemic hemorrhagic fever vaccination needs to be considered. After a patient is bitten by a chinchilla, it is recommended to treat the wound immediately. The wound can be rinsed repeatedly with hydrogen peroxide or tap water for more than 20 minutes, during which the blood in and around the wound is squeezed out forcefully, and later rinsed with saline, followed by drying the water with sterile gauze and disinfection with medical alcohol or iodine volts.
