APPROPRIATE HEALTH CARE

• Self-care.
• Doctor's treatment.
• Wound cleaning.
• Surgical closure if needed.
• Wound will usually be left open to heal to lessen risk of infection.
• Splint hand if it is injured.
• Human bite wounds on the hands should not be primarily closed due to the high risk of infection.

POSSIBLE COMPLICATIONS--Complications from bites can included infection, extensive soft tissue injuries with scarring, hemorrhage, rabies, and sometimes death.

PROBABLE OUTCOME--Wounds should steadily improve and close over by 7-10 days.

How To Treat

GENERAL MEASURES--
