Most times, the body is able to fight off the bacteria naturally using white blood cells and antibodies. Sometimes, however, there are too many bacteria for the body to handle. If bacteria make their way into a wound on the body, serious infection can occur. Signs of infection in wounds include fever, swollen lymph nodes and pus.
Slow Healing
Sometimes before any of the other symptoms begin, a person will notice that the wound is taking a long time to heal. The New Zealand Dermatological Society Incorporated says that if the wound takes more than 10 days to begin to heal, it is most likely infected.
Swollen Lymph Nodes
The lymph nodes in the body play a vital role in protecting the immune system. These glands produce the white blood cells that kill off bacteria, so when there is an infection present in any part of the body, they will swell. For instance, if there is a wound infection on the arm, the lymph nodes located in the underarms will become swollen and tender.
Pus or Discharge Accompanied by Heat
Possibly the most obvious symptom of an infected wound is a yellow- or green-colored, thick pus inside or surrounding the wound. This substance will have a distinctly foul odor to it. It is common for wounds to drain while healing, but the drainage should be clear and thin. The National Pressure Ulcer Advisory Panel states that edema of the wound is a sign of infection as well.
The wound itself and the area that surrounds it will also become red and hot. The surrounding area will also become tender to the touch.
Fever
Drugs.com explains that a fever can signify the presence of an infection of a wound, especially if no other ailments are present. A fever occurs when there is an infection because white blood cells rush to the area to kill off the germs, causing a rise in body temperature. The fever that occurs with a wound infection will vary depending on the severity of the infection.
