If you suspect that a wound is infected, it is important to take action to prevent the infection from worsening. Here are some steps you can take:

1. Clean the wound: Wash the wound immediately by running clean water over it for several minutes. Then, clean the skin around the wound with warm, soapy water. If it is not possible to use clean water, treat the wound with alcohol wipes.

2. Apply an antiseptic ointment: Apply a thin layer of antibiotic ointment, such as Polysporin or Neosporin, to the wound to prevent the spread of infection.

3. Protect the wound: Cover the wound with a sterile bandage or gauze to protect it and retain moisture. Change the dressing at least once a day, or sooner if its wet or dirty, and keep an eye out for signs of infection.

4. Take pain medication: To help with the pain, give an acetaminophen product, such as Tylenol.

5. Seek medical attention: If the wound is severe, deep, or persistent, or if you notice signs of infection such as redness, swelling, warmth, pus, or fever, seek medical attention. A healthcare professional can assess the issue and provide you with appropriate treatment to promote healing and recovery. They may prescribe oral or IV antibiotics, and in some cases, surgery may be necessary.

Remember to always wash your hands with warm water and soap before touching the wound or anything that contacts the injury. Similarly, anything that contacts the injury must be carefully sterilized such as rubbing alcohol on tweezers before using them.
