Specific infections spread by bites


Rabies is an increasingly rare but potentially very serious, even fatal, condition carried by animal bites. Rabies in the UK is rare, but if the bite is from an animal that may have come into the country without going through normal checks, or if you are bitten overseas, then seek immediate medical attention. There is no cure for rabies but early vaccination following a bite can help develop immunity.

Hepatitis B and C

There is a small chance that hepatitis B and C may be transmitted by a human bite. If concerned, seek medical advice.


Tetanus bacteria carry a particular risk when carried deep into a wound with jagged edges or a puncture wound. Animal bites carry a potential risk of tetanus. Tetanus affects the central nervous system and can cause muscle spasms, breathing problems and sometimes death. It is also known as lockjaw because it may tense up the jaw muscles. There is a vaccination for tetanus but immunity is not lifelong and anybody suffering a potentially hazardous injury should seek medical advice on having a booster injection.
