Rat bites and rabies: what to know

Rabies is a serious infection that can affect the nervous system. Whether preventive treatment is advised after a rat bite depends on details such as the animal's behaviour and condition, whether saliva contacted broken skin, the wound site, and guidance from local health authorities. A bite can also introduce ordinary skin bacteria, so rabies assessment should not replace cleaning and examination for wound infection.

Rinse and wash the wound well with soap and running water, remove jewellery near swelling, and apply a clean dressing. Avoid applying harsh chemicals or attempting to close a deep wound yourself. Arrange prompt medical review and share when the bite happened, whether it bled, how the rat behaved, and whether the animal is available for safe official assessment. A clinician will decide whether rabies post-exposure treatment and other wound care are appropriate.

Seek emergency help for heavy bleeding, a deep or crushed wound, numbness, difficulty moving the affected area, or a bite near the eye, mouth, or face. Get same-day advice for fever, increasing pain, warmth, pus, red streaks, or swelling around the wound. Do not wait for neurological symptoms before asking about rabies prevention.

Ask how the exposure is classified, whether vaccination or other post-exposure treatment is needed, whether tetanus protection is current, and how to recognise wound infection.
