What it is
A wound infection happens when germs such as bacteria get into a break in the skin and begin to multiply faster than the body can manage. Not every wound that looks irritated is infected, because healing itself can cause some mild pinkness and tenderness at first.
Commonly described signs a wound is infected include spreading redness, red streaking away from the wound, increasing warmth, swelling, or pain, pus or cloudy drainage, and a foul odor. Fever or chills can also be a sign that an infection is affecting the whole body.
Some people show infection differently. Older adults, people with diabetes, and people with reduced circulation or weakened immune systems may have fewer obvious signs, which is one reason caregivers are encouraged to ask a licensed provider about their own situation.
How it’s traditionally been approached
Traditionally, a clinician evaluates a possible wound infection by looking at the wound, asking about its history, and noting changes in size, color, drainage, odor, and pain. They may also check for fever and consider the person's overall health.
Providers sometimes take a sample from the wound for lab testing, or order other tests, to learn more about what is going on. What is appropriate depends on the individual and is decided by a licensed clinician after an evaluation.
Approaches to infected wounds have long included careful cleaning by a professional, removal of non-healing tissue, protective dressings, and, when a clinician decides it is appropriate, prescription medication. Home health nurses and caregivers often help with monitoring and communication between visits.
How the right wound care specialist may help
The right wound care specialist may help by looking closely at what is causing the wound, how it is staged, and whether signs of infection are present. In a home health setting, a visit may take place in the home, which can make it easier to involve family caregivers.
A visit generally includes a conversation about the wound's history, a gentle look at the area, and notes or measurements so changes can be tracked over time. A provider may also talk through what to watch for between visits and who to contact with concerns.
Questions worth asking a licensed provider include: What is causing this wound? How is it staged? Are there signs of infection? What treatment options exist? How long might healing take? What will insurance cover? Which changes should prompt a call right away?
The whole-person view
Body, mind, and stress affect each other. Caring for a wound, or for someone with one, can bring worry, tiredness, and disrupted sleep, and ongoing stress can make everyday health routines harder to keep up with.
Some people find body-based support, such as the practitioners listed through Somatic Experiences, helpful for feeling more settled. Others prefer talking with a counselor through Therapists.plus, especially when caregiving feels heavy. Neither replaces medical care, and both can sit alongside it.

Keep in mind
- Seek medical care promptly for spreading redness, red streaking, increasing warmth or pain, pus, foul odor, fever or chills, or a wound that is rapidly getting worse.
- Call 911 or go to the ER for heavy bleeding, exposed bone or tendon, signs of sepsis such as confusion, fast heartbeat, or trouble breathing, or a deep or severely contaminated wound, such as from a serious accident.
- Licensed professionals should guide all wound care decisions; this page cannot tell you what is happening with a specific wound.
- If caregiving or worry feels overwhelming and you are in crisis, call or text 988.

Frequently asked questions
What are the signs a wound is infected?
Common signs a wound is infected include spreading redness, red streaking, increasing warmth, swelling or pain, pus, a foul odor, and fever or chills. Not every wound shows all of these signs. If you notice any of them, contact a licensed provider promptly.
When should I go to the doctor for an infected wound?
Seek medical care promptly if you see signs of infection or the wound is rapidly worsening. Go to the ER or call 911 for heavy bleeding, exposed bone or tendon, signs of sepsis, or a deep or severely contaminated wound.
Is redness around a wound always a sign of infection?
No, mild redness can be part of normal healing, especially early on. Redness that spreads, comes with increasing warmth or pain, or forms streaks is more concerning. A licensed provider can tell you what is happening with a particular wound.
Can a wound be infected without pus?
Yes, an infected wound does not always have visible pus. Other signs may include more pain, swelling, warmth, odor, or changes in drainage. Some people, such as older adults or those with diabetes, may show fewer signs, so a provider's evaluation matters.
How do providers check whether a wound is infected?
Providers commonly examine the wound, review its history, and check for fever or other changes. They may also take a sample for lab testing if they feel it is appropriate. What is done depends on the individual and is decided after an evaluation.
Can a home health nurse help with a wound that may be infected?
A home health nurse may be able to assess the wound at home, track changes, and communicate with the physician or wound care team. They can also help caregivers understand what to watch for. Ask a licensed provider what home health services fit your situation and what insurance may cover.
