Wound Infections

What is it?

A wound infection is a damaged skin area where pathogens have entered the open tissue. The infection triggers the body's immune response, causing inflammation and tissue damage and slowing the healing process. 

 

What are the symptoms?

Pain

Redness 

Swelling increases over time

A warm area around the wound

Yellow or green discharge from the wound

Foul odour from the wound

Red streaks surround the wound

Chills

Fever

Aches and pains

Nausea and vomiting

Wounds that are infected may not heal or get worse instead of better

 

Transmission

A wound can become infected when the skin is broken and penetrated by contaminating microorganisms, such as bacteria or fungi. This can occur through touching, scratching, infected droplets entering the wound, poor hygiene, etc.  Contaminating microbes trigger the body's immune system, inflaming damaged tissue and impairing healing. 

 

Common bacteria that may cause a wound infection:

Staphylococcus aureus

Pseudomonas aeruginosa

Escherichia coli (E. Coli)

Proteus mirabilis

Acinetobacter baumannii/haemolyticus

Streptococcus

 

Diagnosis

Diagnosing a wound infection is done by assessing local or systemic symptoms. To confirm the diagnosis and determine the type of microorganism present, your Doctor may recommend that you collect a wound swab for microbiological testing. Microbiological testing can determine if antibiotics are needed and which is most effective against the infection.
