A wound infection occurs when bacteria or other pathogens enter a wound and begin to multiply, leading to symptoms such as increasing pain, swelling, redness, and possibly the production of pus. The skin around the wound may feel warm, and there might be yellow or green discharge or an unpleasant odor. In more severe cases, it can cause fever, chills, aches, and nausea.

Wounds can become infected through various means, such as during surgery, from trauma like falls or accidents, or even from bites or weapons. Common bacteria that may cause a wound infection include:
1. Staphylococcus aureus
2. Pseudomonas aeruginosa
3. Escherichia coli (E. coli)
4. Proteus mirabilis
5. Acinetobacter baumannii/haemolyticus. ETC

Prevention is key, and it’s important to clean wounds properly and monitor them for signs of infection. Minor wound infections may be treatable at home, but more severe or persistent infections require medical attention.
