wound infections:

Wound Infections occur when bacteria, such as bacteria, invade the damaged skin of a wound and multiply. Increased discomfort, swelling, and redness are possible symptoms of such a condition. Severe infections can also induce nausea, chills, and fever.

Minor Wound Infections could be treatable at home. People with more serious or chronic Wound Infections, on the other hand, should seek medical assistance.

This article discusses how to avoid, recognize, and treat an infected wound or infected cut. It also discusses risk factors, problems, when to seek medical attention, and wound infection treatment.

how to recognize wound infections:

An infected wound generally worsens rather than improves. Any discomfort, or swelling even redness surrounding the wound will usually become more intense.

The redness around the injury if bigger than a person’s thumb, may signal for an infection.

Wound Infections can also cause the following symptoms:

  • Skin around the incision that is warm
  • Discharge that is yellow or green in colour
  • The wound releasing a foul odor
  • Crimson skin streaks surrounding the wound
  • Chills and fever
  • Pains and aches
  • Vomiting and nausea

causes/ reasons of wound infections:

When the skin is damaged or punctured, any contaminating germs in and around the wound – often bacteria or fungus – can trigger an infection, as per Wound-Source. This event activates the immune system, inflaming injured tissue and impeding recovery. In other words, Infected wounds occur when bacteria enter and colonize the cut or wound. Bacteria that commonly cause Wound Infections include:

  • The bacteria Staphylococcus aureus
  • The bacterium Pseudomonas aeruginosa
  • The bacteria Escherichia coli (E. Coli).
  • Mirabilis Proteus
  • Bacillus baumannii/haemolyticus
  • Streptococcus

preventing wound infection:

People who have a minor infected area may indeed be able to treat it at home. Whether or not a person can tell if their wound is infected, they can still start by following the steps as given below:

  • Make sure all of the essential equipments are clean. If you’re going to use tweezers, for example, clean them with rubbing alcohol first.
  • Wash your hands thoroughly with soap and warm water, then rinse and dry them.
  • If there is an active bleeding, apply pressure to the cut with a clean bandage or gauze until it stops.
  • Run warm water over the cut or scrape for several minutes to clean it. Clean the surrounding skin with warm, soapy water, but avoid putting soap in the wound.
  • Make sure there is no dirt or debris in the wound, such as grass or stones. To remove the debris, use tweezers or gently wipe the incision with a soft, wet towel.
  • Apply a small coating of antiseptic ointment or petroleum jelly to that same cut or scrape it a bit if desired.
  • Allow the skin to dry before applying gauze or a bandage. Covering small wounds and scratches is typically unnecessary.

these actions will assist a person in preventing infection of a cut or wound:

  • Wash the wound promptly with clean water for several minutes. Then, using warm, soapy water, clean the skin around the wound. If clean water is not available, treat the wound with alcohol wipes.
  • Allow the skin to dry naturally.
  • To treat the wounded area, apply an antibiotic ointment on the wound.
  • Cover the wound with gauze or another appropriate dressing.


After the Clinical Diagnosis of an infected wound or infected cut, the most important step in wound treatment is debridement, which involves thoroughly cleaning the wounded area and removing all callused, infected, and dead tissue, as well as foreign debris and residual content that may have covered the wounded area.

After the wound has been debrided, the cells in the region are stimulated to release cytokines or healing enzymes, allowing the body to repair the wound appropriately. Long-standing wounds that were frequently present or have been there for a year or longer, in case are under the care of a specialist, should heal in 12 weeks.

 An effective treatment plan considers many factors, including addressing underlying conditions, such as diabetes-related poor blood flow and oxygen, and nutritional deficiencies as well as the length and nature of the infection. Individualized therapies, which may include IV antibiotics and topical medications, as well as targeted hydrotherapy and hyperbaric oxygen therapy provided, are frequently administered in collaboration with other clinicians.

risk factors:

Cuts, grazes, and other skin openings can become infected when bacteria enter and grow in the wound. Bacteria generally enters the body through the debris, the environment, or the object that causes the injury.

To reduce the risk of infection, it is critical to clean and protect the wound properly.

The likelihood of Wound Infection increases if:

  • The wounded area is deep, big, or has a jagged edge.
  • If the wound has been in contact with dirt or other harmful particles
  • The wound was caused due to the bite by an animal or another human.
  • If the wound is due to carelessness of infected stitches
  • The wound was caused by an injury caused by a filthy, rusted, or germ-containing instrument.
  • Infection risk might also be increased by certain medical disorders or any environmental variables. 

These are some examples:

  • diabetes
  • a compromised immune system, such as that found in HIV patients or those on immunosuppressive medicines
  • lack of movement, as in persons who spend the most of their time in bed
  • Aging- elderly persons are more vulnerable to Wound Infection, nutrition and vitamin deficits

when to see a doctor:

If a person has a wound, he or she should seek medical assistance if:

  • The wound is deep, big, or has jagged edges.
  • When the wound’s margins do not keep together, indications of infection such as fever, increased pain or redness, or wound discharge arise.
  • It is not feasible to thoroughly clean the wound or remove all particles/debris, such as grass or stones.
  • The wound was caused as a result of a bite  of an animal or human or an injury from a dirty, rusted, or filthy instrument.
  • If blood is spurting from the cut or applying pressure to the wound does not stop the bleeding, seek emergency medical treatment.


  1. How can I know whether my wound is healed or infected?

Feeling warm to the touch, discharge or pus in wound, long-lasting discomfort, or fever are all signs that a wound is not healing correctly and may be infected. 

  1. How do nurses prevent Wound Infections?

Nursing Interventions to Prevent Wound Infection Risk are as follows:

  • Maintain proper asepsis when changing dressings, caring for wounds, administering intravenous treatment, and handling catheters.
  • Before using any items, ensure that they have been adequately cleaned or sterilized.
  • Before making touch with the patient, washing hands and making sure about their hand hygiene.
  1. How should an infected wound be cleaned?

To clean the skin around the area, use warm, soapy water, being careful not to get any soap within the wound. Do check whether the wound is clean and free of any dirt or debris, such as pebbles or grass if not then use tweezers or a soft, wet towel to gently and carefully rub the wound to remove any debris. 

  1. How to tell if a wound is healing?

A  typical cut and puncture wound heals in three stages: 

  • bleeding
  • clotting
  • scabbing

if you see the above in your case that means wound is healing.
