How do you treat an infected leech bite?

To treat an infected leech bite, first clean the area gently with soap and water to remove any debris. Apply an antiseptic to prevent further infection, and if signs of infection such as redness, swelling, or pus develop, consider using an over-the-counter antibiotic ointment. Keep the bite clean and covered, and monitor for worsening symptoms. If the infection does not improve or if you experience severe symptoms, seek medical attention.
