Indicators of wound infection include redness, swelling, purulent exudate, smell, pain, and systemic illness in the absence of other foci. Subtle signs of local wound infection include unhealthy “foamy” granulation tissue, contact bleeding, tissue breakdown, and epithelial bridging.
Clinical Presentation. Signs and symptoms of wound infection include increased wound size/depth, increased exudate, erythema, malodour or other systemic signs of infection with or without increased neuropathic pain, muscle spasm or autonomic dysreflexia.
Signs that a wound is not healing properly and may be infected include feeling warm to the touch, swelling, discharge or pus, long lasting pain, or fever.
Localized infection is often characterized by the classical signs and symptoms of inflammation – pain, heat, swelling, redness and loss of function.
The most common of these include the bacteria Staphylococcus, Streptococcus, and Pseudomonas.
The classic signs of infection are heat, redness, swelling, and pain. Additional signs of wound infection include increased exudate, delayed healing, contact bleeding, odour, and abnormal granulation tissue.

If your cut is infected, the infection spreads to your skin's deep tissues, called the cellulitis. Once there, the infection can reach your bloodstream, allowing harmful bacteria to infect your entire body. If this happens, you'll start to feel sick all over.
The most common pathogens that cause wound infections include: Bacteria – the most-common pathogen, including Staphylococcus (staph), Streptococcus (strep), MRSA, Clostridium, Cellulitis, to name a few. Fungi – yeast and mold including Candida, Cladosporidium, and Aspergillus, among others.
Local complications include delayed and non-healing of the wound, cellulitis, abscess formation, osteomyelitis as well as further wound breakdown. Systemic complications include bacteremia with the possibility of distant hematogenous spread and sepsis.
Systemic disorders can have gastrointestinal (GI) manifestations which are characterized by nausea, vomiting, diarrhea, constipation, abdominal pain, jaundice, and abnormal liver function tests. These gastrointestinal symptoms can be signs of various immunologic, infectious, and endocrine diseases.
Sepsis happens when an infection you already have triggers a chain reaction throughout your body. Infections that lead to sepsis most often start in the lung, urinary tract, skin, or gastrointestinal tract. Without timely treatment, sepsis can rapidly lead to tissue damage, organ failure, and death.
The factors discussed include oxygenation, infection, age and sex hormones, stress, diabetes, obesity, medications, alcoholism, smoking, and nutrition. A better understanding of the influence of these factors on repair may lead to therapeutics that improve wound healing and resolve impaired wounds.
Sepsis Diagnosis
Signs of infection on an X-ray, CT scan, or ultrasound. A high or low white blood cell count. A low number of platelets in your blood. Low blood pressure.
Infection can develop any time between two to three days after the cut occured, until it's visibly healed. Luckily, infected cuts can be prevented with proper wound protection using Elastoplast plasters. Recognising signs of wound infection is important so you know when to see your doctor for the appropriate treatment.
The prodromal period occurs after the incubation period. During this phase, the pathogen continues to multiply and the host begins to experience general signs and symptoms of illness, which typically result from activation of the immune system, such as fever, pain, soreness, swelling, or inflammation.
As the wound begins to dry, a crust starts to form in the outer layer. If the crust is yellowish and if there is a formation of pimples on or near the wound, it could be septic. Sores that look like blisters. If there is a formation of sores which look like pockets of fluid around the area, they could be septic.
Fever (this is sometimes the only sign of an infection). Chills and sweats. Change in cough or a new cough. Sore throat or new mouth sore.
Contact a doctor if you have any of the following: Redness spreading out from the wound. Increased pain or swelling. Difficulty moving the affected area.
Whether it's a surgical wound or one that seemed minor at first but is getting worse instead of better, any wound that's infected should be evaluated by a medical provider. Signs a wound may be infected include: Increasing pain or redness. Drainage or bleeding that won't stop.
