Even a small wound can turn serious if left untreated. While most cuts and scrapes heal naturally, some wounds can become infected — especially among the elderly, diabetic patients, or individuals with poor circulation.
If you notice any of the warning signs below, it may be time to get professional wound care.
1. Increasing Redness and Swelling
A little redness around a new wound is normal, but spreading redness, warmth, and swelling can indicate an infection.
If the area feels hot to the touch or the redness keeps expanding, it’s a sign that bacteria are growing under the skin.
👉 Tip: For diabetic patients, redness might be harder to notice due to reduced sensation — check wounds daily, especially on the feet.
2. Persistent Discharge or Pus
A healthy wound may have clear fluid during the healing process.
However, if you see yellow, green, or foul-smelling pus, that’s a clear sign of infection.
The body is trying to fight bacteria, and it needs professional cleaning and dressing.
Why it matters: Diabetic or elderly patients often have weaker immune systems, so pus buildup can lead to cellulitis or even sepsis if ignored.
3. Fever or Feeling Unwell
When the infection spreads beyond the wound, the body reacts with a fever, chills, or fatigue.
If you feel unusually tired or feverish, it means your body is fighting a deeper infection.
⚠️ Seek help immediately — this could indicate a systemic infection that requires antibiotics or professional wound assessment.
4. Slow or Non-Healing Wounds
Most minor wounds heal within a few days to two weeks.
If your wound shows no signs of improvement after this period — or looks worse — it could be a chronic wound.
| Common Causes of Slow Healing | Why It Happens |
|---|---|
| Diabetes | Poor blood flow delays tissue repair |
| Ageing | Thinner skin and slower cell regeneration |
| Poor nutrition | Lack of protein or vitamin C slows healing |
| Infection | Bacteria prevent wound closure |
💡 Professional wound care can help identify the cause and use advanced dressings or debridement to promote healing.
5. Increased Pain or Odour
Pain that gets worse instead of better is another warning sign.
Infected wounds may also produce a strong, unpleasant smell, especially if there’s dead tissue.
A foul odour often means the wound isn’t getting enough oxygen — something that only proper cleaning and dressing can fix.
When to Seek Professional Wound Care
You should contact a professional wound care nurse if:
- The wound is larger than 2 cm or deep
- You have diabetes or poor circulation
- The wound hasn’t improved after 7–10 days
- You notice spreading redness, pus, or odour

How to Prevent Wound Infection Before It Starts
Keeping your wound clean and covered is the best way to stop infection before it begins. Follow these simple steps for safer, faster healing:
- Wash your hands first – Always clean your hands with soap and water (or sanitizer) before and after touching the wound.
- Rinse gently – Use clean water or sterile saline to remove dirt. Avoid harsh antiseptics like alcohol or hydrogen peroxide.
- Apply a clean dressing – Cover the wound with sterile gauze to block bacteria and maintain a moist healing environment.
- Change dressings regularly – Replace whenever it’s wet or dirty, and re-clean before reapplying.
- Avoid irritation – Keep the area dry, don’t scratch, and wear loose clothing.
💡 For seniors and diabetics:
Even small cuts can turn serious due to poor circulation or slow healing. Check your wounds daily and seek professional care if you notice redness, swelling, or discharge.

Frequently Asked Questions
Look out for redness, swelling, warmth, or pus coming from the wound. If there’s pain, a foul smell, or fever, seek professional care immediately.
Most wound infections won’t heal on their own. Without proper cleaning and treatment, bacteria can spread deeper into the tissue or bloodstream, leading to more serious complications. It’s best to get your wound checked by a professional nurse or doctor.
In most cases, wound infections develop within 24 to 72 hours after the injury. Early warning signs include redness, swelling, warmth, pain, or cloudy discharge around the wound. However, people with diabetes, poor circulation, or weakened immune systems — such as elderly patients — should check their wounds daily, as symptoms may appear more slowly or be less obvious.
Ignoring an infected wound can lead to cellulitis, abscess formation, or sepsis. For diabetic patients, it can even result in amputation if not treated in time. Always seek professional help if a wound isn’t improving after a few days.
It’s best to avoid harsh antiseptics because they can damage new skin and slow healing. Use clean water or sterile saline instead.
Once a day is ideal — or anytime it becomes wet, dirty, or loose. Always wash your hands before and after changing dressings.
People with diabetes, poor circulation, or elderly individuals should always get professional wound care. These conditions slow down healing and increase infection risk.
