How to treat a human bite
Ask for the biter's medical history.
If it's possible, ask the person who bit you for their medical history. You want to make sure they have current vaccinations and do not have other serious medical conditions such as hepatitis.
This can help your figure out if you should see a doctor and what type of treatment is the best for you. If you can't get the medical history of the person who bit you, administer first aid and then see your doctor.
