When Atopic Dermatitis Looks Infected: Weeping, Crusting and Fever That Need a Doctor Soon

The behind-the-knee patch had been there for years. Dry, itchy, the kind of thing you learn to live with. Then one week it changed. It started to glisten, then to leak, and by Thursday the sheets had small yellow stains where the skin had touched them. That night the thermometer read higher than it should. This is the moment many families first meet the phrase infected atopic dermatitis, and the moment they most need a clear explanation rather than a search page full of unrelated results.

Eczema and infection are not the same problem wearing the same coat. A flare itches; an infection tends to hurt. A flare is dry or slightly moist; an infection weeps, crusts and sometimes throws off a fever. The distinction matters because the treatments are different, and because a small number of skin infections in people with eczema move fast enough to need same-day care.

What follows is a plain account of what is actually happening in the skin, how clinicians tell one from the other, and where the genuine red flags sit.

What is a secondary bacterial infection in atopic dermatitis?

Atopic dermatitis is the medical name for the most common form of eczema: a long-term condition in which the skin is dry, itchy and prone to inflamed flares. A secondary bacterial infection is what happens when bacteria take advantage of that already-damaged skin and multiply inside it. The word secondary simply means the infection arrived second; the eczema was there first and opened the door.

Healthy skin is a remarkably effective wall. Its outer layer is packed with fats and proteins that keep water in and microbes out, and its surface is slightly acidic, which most harmful bacteria dislike. In atopic dermatitis that wall has gaps. The NHS describes how scratching breaks the surface and lets bacteria enter, and how eczema skin tends to carry more Staphylococcus aureus than skin without eczema.

Two organisms account for most cases. Staphylococcus aureus, usually just called staph, is by far the most frequent. Streptococcus pyogenes, the same bacterium behind strep throat, is the second. Both can produce impetigo-type changes: weeping, golden crusts and small pus-filled spots. When the infection reaches the deeper layers of the skin it becomes cellulitis, which the NHS describes as a spreading area of hot, swollen, painful skin that can be accompanied by fever and feeling unwell.

A secondary infection is not a sign that someone has been careless with their skin. It is a predictable complication of a barrier that does not seal properly, which is why clinicians who manage eczema watch for it routinely. The practical lesson is that infected atopic dermatitis is a different diagnosis from a flare, and that treating it as just a bad week of eczema can allow it to spread.

How do I know if my eczema is infected?

Most people cannot be certain on their own, and they are not expected to be. What you can do is notice the ways a patch has stopped behaving like your usual eczema, and take those changes to a clinician who can confirm what is going on.

The first shift is often texture. Eczema is typically dry, rough and flaky; an infected patch turns wet. Fluid may be clear at first, then yellow, and as it dries it forms crusts the color of honey or dark caramel. Small blisters or pus-filled bumps may appear at the edges. The NHS lists these features, together with skin that becomes very red or sore, as signs that eczema may have become infected.

The second shift is sensation. Eczema itches. Infection tends to hurt, throb or feel hot to the touch, and the surrounding skin may swell. In people with darker skin tones the redness clinicians talk about may be hard to see; the skin may instead look darker, purple or gray, so warmth, swelling and pain become more useful clues than color.

The third shift is behavior. A flare usually responds within days to the care plan you already have. An infection often does not, or gets worse despite it, and may spread beyond the original patch.

The fourth shift is the rest of the body. Fever, chills, feeling generally unwell, or swollen glands near the affected skin all point beyond a simple flare, and the NHS advises contacting a doctor promptly when eczema is accompanied by these features.

None of these signs is a diagnosis. They are reasons to be seen. A clinician can examine the skin, take a swab if needed, and separate bacterial infection from a viral one or from an unusually severe flare, each of which is handled differently.

What does bacterial dermatitis look like?

Clinicians use a few informal labels for what infected eczema looks like, and knowing them helps when you describe your skin over the phone.

Impetiginized eczema is the most common picture. The word comes from impetigo, a superficial bacterial skin infection, and it describes eczema that has developed the classic impetigo signs on top: oozing, then crusts that look like dried honey or brown sugar stuck to the skin. The NHS notes that impetigo often begins with red sores or blisters that burst and leave crusty patches, and that in people with eczema it tends to appear on skin that is already damaged.

Folliculitis is infection of the hair follicles. It shows up as clusters of small pus-topped bumps, each centered on a hair, often on the thighs, buttocks or trunk. It can be mistaken for a flare of small eczema spots, but the white or yellow heads give it away.

Cellulitis is the deeper and more serious form. The NHS describes cellulitis as skin that is hot, swollen and painful, sometimes with a spreading edge and blistering, and it often comes with fever or feeling unwell. On darker skin the area may look darker than the surrounding skin rather than red. Cellulitis is the version most likely to need urgent assessment because the infection has moved past the surface.

A fourth appearance is fissured infected eczema: deep cracks at the finger joints, behind the ears or in the folds of the elbows that weep and refuse to close. These cracks are both a symptom of infection and a route for more bacteria to enter.

Photographs help. A daily picture in the same light lets a clinician see whether an area is expanding, which is one of the most useful pieces of information you can bring to an appointment for infected atopic dermatitis.

Why the skin barrier in atopic dermatitis lets bacteria in

To understand why eczema and infection travel together, picture the outer skin as a brick wall. The bricks are flattened skin cells; the mortar is a mix of fats and proteins that seals the gaps. In many people with atopic dermatitis, the mortar is thin. The NIH’s institute for skin diseases (NIAMS) explains that genetic variants affecting a barrier protein called filaggrin are linked to atopic dermatitis, and that a weakened barrier lets moisture out and irritants and microbes in.

Three things then happen at once. Water escapes, so the skin dries and cracks, and every crack is an open gate. The surface becomes less acidic than healthy skin, and Staphylococcus aureus grows more happily at that higher pH. And the skin’s own chemical defenses, small proteins that normally kill bacteria on contact, are produced in smaller amounts in inflamed eczema skin.

Scratching finishes the job. Mayo Clinic notes that the itch-scratch cycle damages skin, worsens inflammation and raises the risk of infection. Fingernails carry bacteria, and each scratch drives them deeper while creating fresh breaks in the surface.

There is a feedback loop here that clinicians think about constantly. Staph does not just sit on the skin; it releases toxins that trigger more inflammation, which weakens the barrier further, which allows more staph to colonize. This is one reason a flare and an infection can be hard to pull apart: the bacteria may be driving the flare.

The practical consequence is that keeping the barrier as intact as possible, through regular moisturizing and controlling inflammation as advised by your care team, is not cosmetic. It is the main defense against infection. The NHS advises using emollients generously and often as the foundation of eczema care. When that foundation slips, whether from a stressful month, a change in season or a new irritant, infection risk climbs with it.

Staph infection in eczema: why one bacterium dominates

If you have eczema, you almost certainly share your skin with Staphylococcus aureus. That is not a judgment; the NHS notes that most people with atopic eczema carry the bacterium on their skin, often without any sign of infection. The question is not whether staph is present but whether it has moved from quiet passenger to active invader.

Staph is well suited to eczema skin. It binds readily to proteins exposed when the barrier is damaged, it tolerates the slightly less acidic surface of inflamed skin, and it produces a range of toxins. Some of those toxins act as superantigens, molecules that provoke an exaggerated immune response and make the underlying eczema angrier. Others break down the connections between skin cells, which is what produces the blistering and peeling seen in some staph infections.

Colonization and infection sit on a spectrum. At one end, staph lives on the skin surface without symptoms. In the middle, heavy colonization may make eczema harder to control even without obvious pus or crusts. At the other end, the bacteria breach the surface and cause impetiginized eczema, folliculitis or cellulitis, with the weeping, crusting and pain that bring people to a doctor.

This spectrum explains a recurring frustration. Some people are treated for a presumed infection and improve dramatically; others are treated repeatedly and see little change, because the real driver is inflammation rather than infection. Clinicians weigh this carefully, and current NHS guidance discourages routine antibiotics for eczema that is merely colonized rather than clearly infected, both to avoid side effects and to reduce antibiotic resistance.

Resistant strains, including methicillin-resistant Staphylococcus aureus, do occur in eczema. A swab sent for culture tells the laboratory which antibiotics the bacterium responds to, which is why a clinician may take one before choosing treatment or after an initial treatment has not worked.

Eczema herpeticum symptoms: the viral emergency that mimics a flare

Not every infected eczema patch is bacterial. Eczema herpeticum is an infection of eczema skin with the herpes simplex virus, the same virus that causes cold sores. The NHS lists it as a rare but serious complication of atopic eczema that needs urgent medical attention, and it is the one condition in this article where hours genuinely matter.

The appearance is distinctive once you know it. Instead of honey-colored crusts, eczema herpeticum produces clusters of small, uniform blisters, often described as punched-out because they leave shallow round sores of similar size when they burst. The NHS describes areas of painful eczema that get worse quickly, groups of fluid-filled blisters that break open and leave small open sores, and a person who feels hot, shivery and generally unwell. The face and neck are common sites, though it can appear anywhere eczema is active.

Pain is the giveaway. Eczema itches; herpeticum burns. Many people describe the affected skin as feeling raw or stinging in a way their eczema never has. Fever, swollen glands and a child who is unusually quiet or listless complete the picture.

Why the urgency? The virus can spread rapidly across large areas of skin, and in rare cases it reaches the eyes or causes a body-wide illness. Treatment is with antiviral medicines, which work by blocking the enzyme the virus uses to copy itself; they cannot undo damage already done, so they work best the earlier they are started. That decision, including whether treatment is given by mouth or in hospital, sits with the assessing clinician.

One more point matters for families. Herpes simplex is passed by skin contact, and a cold sore on a relative can be the source. People with active eczema should avoid kissing or close skin contact with anyone who has a cold sore, a precaution the NHS specifically recommends.

Fever with infected atopic dermatitis: when a skin problem becomes a whole-body one

Fever changes the category of the problem. Eczema on its own does not raise body temperature. When a temperature appears alongside weeping or crusting skin, the body is telling you the infection is no longer confined to the surface, or that the immune system is mounting a systemic response to it.

Several mechanisms can produce this. Cellulitis, the deeper skin infection described by the NHS as hot, swollen and painful skin often accompanied by fever and feeling unwell, is the most common. Eczema herpeticum characteristically causes fever. Less often, bacteria enter the bloodstream from infected skin, or staph toxins provoke a body-wide inflammatory response. In infants and young children, whose skin surface is large relative to their body size and whose immune systems are still maturing, these events can unfold faster.

Other signs that accompany fever deserve equal attention: a rapid heartbeat or breathing, drowsiness or confusion, refusing fluids, or a red or dark streak tracking away from the infected area along the line of a vein. Swollen, tender lymph glands in the neck, armpit or groin on the same side as the infection suggest the immune system is fighting hard.

Fever with infected skin is a same-day matter. In many cases the outcome is straightforward: an examination, a swab, and a course of treatment chosen by the clinician, with the temperature settling over the following day or two. Occasionally it means admission for intravenous treatment and observation. The point is that this is a decision for a clinician to make in person, not one to make at home by waiting to see whether the fever passes.

Parents often ask whether they should give a fever-reducing medicine before the appointment. That is a reasonable question for the clinician you are about to speak to, and their answer will depend on the child’s age, weight and history.

Six common skin infections and how they differ from an eczema flare

People searching for infected eczema often land on lists of skin infections without a sense of which ones actually matter for someone with atopic dermatitis. The table below sets out six that clinicians see most often in eczema-prone skin, what causes each, and how each tends to differ from a plain flare. It is a guide to describing your skin, not a tool for diagnosing it.

Infection	Cause	Typical appearance on eczema skin	How it differs from a flare
Impetigo (impetiginized eczema)	Staph aureus or Streptococcus	Weeping, honey-colored crusts, small pus spots	Wet and crusted rather than dry and flaky; often painful
Folliculitis	Usually staph	Clusters of pus-topped bumps centered on hairs	Each bump has a white or yellow head
Cellulitis	Staph or Streptococcus in deeper skin	Hot, swollen, painful area that spreads; fever common	Involves the whole thickness of the skin; person feels unwell
Eczema herpeticum	Herpes simplex virus	Groups of uniform small blisters leaving punched-out sores; pain, fever	Burning pain, rapid spread, systemic illness
Molluscum contagiosum	Poxvirus	Small, firm, pearly bumps with a central dimple	Painless; slow to appear and to fade
Fungal infection (tinea or candida)	Dermatophyte fungi or yeast	Ring-shaped scaly patch with raised edge, or moist red rash in folds	Often has a clear edge; may worsen with steroid creams alone

Two of these, cellulitis and eczema herpeticum, are the ones that carry real urgency and are the reason this article exists. Impetigo and folliculitis are common and usually respond well to treatment; the NHS notes impetigo typically improves within 7–10 days once treated. Molluscum and fungal infections are slower, less dramatic, and matter mainly because they are sometimes mistaken for eczema and treated with the wrong cream. A clinician can usually tell them apart on examination, sometimes with a swab or a skin scraping to confirm.

Who is usually treated straight away, and who is asked to wait and watch

Clinicians sort suspected infected eczema into rough tiers, and understanding those tiers takes some of the anxiety out of the wait for an appointment.

Same-day or emergency assessment is the norm for anyone with suspected eczema herpeticum, anyone with fever alongside weeping or spreading skin, infants under a few months old with infected-looking eczema, anyone with signs of cellulitis such as a hot, swollen, painful area that is enlarging, and anyone whose immune system is weakened by illness or medication. The NHS advises seeking urgent help for eczema herpeticum and for cellulitis with fever or rapid spread. Infection near the eyes also moves up the list because of the risk to vision.

Prompt but routine assessment, typically within a day or two, suits a localized patch of weeping, crusted eczema in an otherwise well person. This is the most common scenario. The clinician will examine the area, may take a swab, and will decide whether an antibiotic is needed, whether it should be applied to the skin or taken by mouth, and how the underlying eczema treatment should continue. Those choices belong to the prescriber and depend on the extent of infection, previous cultures and any allergies.

Watch and wait applies to a different group: people whose eczema has flared but shows no crusting, pus, pain, spreading or fever. Here clinicians often step up the usual eczema plan first and review, because antibiotics do not help inflammation that is not infected and can cause side effects and resistance. If the skin then develops infection signs, the plan changes.

Recurring infection is its own category. Someone who has needed treatment for infected eczema several times in a year is usually reviewed more thoroughly: nasal swabs of the person and sometimes household members to check for staph carriage, a look at whether the eczema itself is undertreated, and consideration of measures to reduce bacterial load on the skin under supervision.

What actually happens at the appointment for infected eczema

The visit is usually shorter and less alarming than people expect. It has three parts: looking, sampling and deciding.

Looking comes first. The clinician examines the affected skin and the skin around it, checks for warmth and swelling, and looks at the whole body for other patches, blisters or lymph gland swelling. They will ask when the change began, whether it hurts or itches, whether anyone at home has a cold sore or a skin infection, what treatments you have been using and how often, and whether there is fever.

Sampling may follow. A swab is a soft cotton tip rolled across the weeping area and sent to a laboratory. For suspected bacterial infection it identifies the organism and which antibiotics it responds to, with results typically back in a few days. For suspected eczema herpeticum a swab from the base of a fresh blister can be tested for the virus. Not everyone needs a swab; for a small, typical patch a clinician may treat on appearance alone. Blood tests are reserved for people who are unwell or have fever.

Deciding is the clinician’s task, and the options fall into recognizable groups. Antibiotics, whether applied to the skin or taken by mouth, kill or stop the growth of bacteria; the choice of route depends on how much skin is involved. Antiviral medicines block the herpes virus from copying itself and are used for eczema herpeticum, sometimes in hospital. Anti-inflammatory treatment for the eczema itself, such as topical corticosteroids or calcineurin inhibitors, may be continued, paused or adjusted; this is a decision your prescriber makes case by case, and it is not one to make on your own.

Some clinicians also discuss measures to reduce bacterial load on the skin, such as antiseptic washes or diluted bleach baths. Mayo Clinic mentions diluted bleach baths as an option some clinicians suggest to reduce bacteria; the evidence for how much they help is mixed, and they should only be used exactly as your care team directs.

What the following days and weeks usually look like

Recovery from infected atopic dermatitis tends to run in two overlapping phases: the infection settling, then the eczema underneath catching up.

For a bacterial infection treated appropriately, the first change most people notice is that the weeping slows and the pain eases, often within the first couple of days. Crusts begin to dry and lift. The NHS notes that impetigo usually clears within 7–10 days of starting treatment, and that a person stops being contagious 48 hours after treatment begins or once the crusts have dried, whichever comes first. That 48-hour figure is the basis for common return-to-school advice. If nothing has improved after two or three days, or the area is still spreading, the clinician needs to know, because the organism may be resistant to the chosen antibiotic or the diagnosis may need revisiting.

Cellulitis follows a slower curve. Redness and swelling can look slightly worse in the first day even when treatment is working, then recede over the following week. Fever should settle early; if it does not, that is a reason to be reassessed. The NHS advises returning for review if cellulitis symptoms worsen or fail to improve after a few days of treatment.

Eczema herpeticum, once antiviral treatment starts, typically stops producing new blisters within a few days, and the sores crust and heal over the following one to two weeks. Scarring is uncommon but can occur where sores were deep.

Then the eczema phase begins. Infection inflames the skin, and that inflammation does not vanish the moment the bacteria do. Many people find the patch stays red, itchy and fragile for weeks and needs consistent moisturizing and whatever anti-inflammatory plan the care team sets. Skin may look darker or lighter than the surrounding area for some months as it heals; this post-inflammatory color change is not scarring and usually fades.

A follow-up conversation is worth requesting, not because something is expected to go wrong, but because it is the natural point to ask why the infection happened and what might make the next one less likely.

Weeping eczema: what to do at home while you wait to be seen

The hours between noticing the change and reaching a clinician can feel long. There is a short list of sensible things to do, and a shorter list of things not to do.

Keep the area clean and covered lightly. Gentle washing with lukewarm water and a fragrance-free wash, patting rather than rubbing dry, and covering weeping skin with a clean non-stick dressing or loose cotton reduces spread to other areas and to other people. Change any covering when it becomes damp.

Do not pick, pop or scrub crusts and blisters. Removing crusts exposes raw skin and spreads bacteria; blisters that are burst by hand tend to leave larger sores. Trimmed fingernails and, for children, cotton gloves at night reduce the damage from scratching in sleep.

Keep towels, flannels, bedding and clothing separate from the rest of the household, and wash them at a warm setting. The NHS advises this for impetigo because both staph and strep spread by direct contact and via shared items. Handwashing after touching the area protects everyone else.

Continue your prescribed eczema treatment unless your care team has told you otherwise. Some people stop their anti-inflammatory creams the moment they suspect infection, fearing they will feed it. Whether to pause or continue is a clinical judgment that depends on the type of infection, and it is a question to ask rather than a decision to make alone. Emollients, the plain moisturizers that form the base of eczema care, are generally continued, though many clinicians advise using them from a pump or a clean spoon rather than fingers dipped into a tub, which can seed the tub with bacteria.

Photograph the area once a day in the same light and note temperature readings and how the person is feeling. This record is more useful to a clinician than any description.

Finally, if fever appears, the area spreads noticeably within hours, the pain becomes severe, or small uniform blisters begin to cluster, do not wait for the booked appointment. Seek urgent care.

What people often get wrong about infected atopic dermatitis

Some beliefs about infected eczema are harmless. Others delay care or make the skin worse. These are the ones clinicians hear most.

The first is that infection means poor hygiene. It does not. The NHS is explicit that people with atopic eczema are prone to infection because of the condition itself, not because of how clean they are. Over-washing with harsh products strips the barrier further and can increase risk.

The second is that all crusting means bacteria. Dried eczema fluid can form pale crusts without infection, and eczema herpeticum crusts too, but from a virus. Treating a viral infection with antibiotics alone does nothing for the virus, which is why the distinction is made by a clinician rather than at the bathroom mirror.

The third is that steroid creams cause infection and must be stopped the instant infection is suspected. Uncontrolled inflammation is itself a major driver of bacterial overgrowth, and abruptly stopping treatment can trigger a rebound flare. Whether to continue, pause or change anti-inflammatory treatment during an infection is a case-by-case decision that belongs to the prescriber.

The fourth is that a normal temperature rules out anything serious. Cellulitis and even early eczema herpeticum can present without fever, particularly in the first day. Pain, rapid spread and a person who seems unwell carry weight even when the thermometer is reassuring.

The fifth is that antibiotics are the cornerstone of eczema care. They are a tool for genuine infection, not for colonization or ordinary flares, and repeated courses breed resistance. The long-term defense against infection is a well-maintained barrier and well-controlled inflammation.

The sixth is that swimming pools, pets or particular foods are usually to blame. Chlorinated pools do not cause staph infections, pets are rarely the source, and food allergy is a separate question from skin infection. The most common trigger is simply a barrier that has been struggling for a while, often after a period when treatment slipped.

Questions to ask your care team

A good appointment is a two-way conversation. These questions help you leave with a plan you understand and can follow, and they signal to the team what matters to you.

• Is this a bacterial infection, a viral one, or a severe flare, and how confident are you? What would change your mind?
• Are you taking a swab, and if so, when will the result be back and how will I hear about it?
• Should I continue, pause or change my usual eczema creams while this is being treated? For how long?
• What improvement should I expect to see, and by roughly when? What would tell me the treatment is not working?
• Which specific changes mean I should come back urgently rather than wait for a routine review?
• How do I stop this spreading to other parts of my skin or to other people at home, and when can my child return to school or nursery?
• Is there any reason to check whether I or someone in my household is carrying staph in the nose, and would treating that help?
• Have I been having infections often enough that we should look again at how well the eczema itself is controlled?
• Are there measures to reduce bacteria on the skin that you would recommend for me specifically, and how exactly should I use them?
• Should I be referred to a dermatologist, and what would that add?

Bring your daily photographs and a note of temperatures and any medicines already taken. If you are caring for a child, ask the team how they would like to be contacted out of hours if the picture changes, because infections in eczema tend to change fastest at night. Write down the answers or ask for a printed summary; the details of what to continue and what to pause are easy to muddle once you are home and tired.

When to call your doctor

Most infected eczema is treated successfully in a routine appointment. A smaller group of situations should not wait, and recognizing them is the single most useful thing this article can offer.

Seek urgent care the same day, through your doctor, an urgent care service or emergency services depending on severity, if any of the following occur alongside eczema:

• Fever, chills or shivering, or a person who seems unusually drowsy, floppy, confused or hard to wake.
• Clusters of small, uniform blisters that burst to leave shallow punched-out sores, especially with burning pain or rapid spread; the NHS describes these as features of eczema herpeticum, which needs urgent treatment.
• A hot, swollen, painful area of skin that is visibly enlarging over hours, or a red or dark streak tracking away from it.
• Infection or blistering on or around the eyes, or any change in vision.
• Rapid breathing, a racing heart, refusing to drink, or in babies fewer wet diapers than usual.
• Severe pain out of proportion to what the skin looks like.

Book a prompt appointment, within a day or two, if a patch has started weeping, crusting with honey-colored scabs or developing pus spots, if it is more painful than your eczema usually is, if it is not improving or is spreading despite your usual care, or if you have been told to watch a flare and it has changed character.

Contact your care team again during treatment if there is no improvement after two to three days, if the area continues to spread, if new blisters appear, or if fever develops or returns. The NHS advises this kind of reassessment for both impetigo and cellulitis that fail to improve.

Everything here is a prompt to be seen, not a verdict. The decision about what the skin is showing, what to treat it with and whether hospital care is needed belongs to the clinician examining you. If you are unsure whether something counts as urgent, calling and describing it is always the right move.

Frequently asked questions

How to tell if eczema is infected rather than just flaring?

Infected eczema usually turns wet where a flare stays dry: it weeps, forms honey-colored crusts or pus spots, and often becomes painful, hot or swollen rather than simply itchy. It may spread quickly, fail to respond to your usual care, or come with fever or swollen glands. These are reasons to be examined by a clinician, who can confirm the cause with an examination and, if needed, a swab, because bacterial, viral and inflammatory causes are treated differently.

What is a secondary bacterial infection in atopic dermatitis?

It is a bacterial infection that develops on skin already damaged by eczema, so the eczema came first and the infection second. Staphylococcus aureus is the usual culprit, with Streptococcus pyogenes less often. Cracks, scratching and a weakened barrier let the bacteria into the skin, where they cause weeping, crusting and sometimes deeper infection such as cellulitis. The NHS describes this as a common complication of atopic eczema rather than a sign of poor hygiene.

What does bacterial dermatitis look like?

The most common picture is impetiginized eczema: oozing skin with crusts the color of honey or brown sugar, sometimes with small pus-filled spots at the edges. Folliculitis shows as clusters of pus-topped bumps centered on hairs. Cellulitis, the deeper form, appears as a hot, swollen, painful area that spreads and may come with fever. On darker skin tones the area may look darker or purple rather than red, so warmth, swelling and pain are the more reliable clues.

What are 6 common skin infections seen with eczema?

Clinicians most often see impetigo, folliculitis and cellulitis, all bacterial and usually caused by staph or strep; eczema herpeticum, caused by the herpes simplex virus; molluscum contagiosum, a slow viral infection producing pearly dimpled bumps; and fungal infections such as ringworm or yeast rashes in skin folds. Cellulitis and eczema herpeticum are the two that need urgent assessment. The others matter mainly because they can be mistaken for eczema and treated with the wrong cream.

Is a staph infection in eczema contagious to other people?

Yes, the bacteria can pass by direct skin contact and through shared towels, bedding and clothing, which is why the NHS advises keeping these items separate and washing hands after touching affected skin. For impetigo, the NHS states a person stops being contagious 48 hours after starting treatment or once the crusts have dried. Household members with healthy skin are at lower risk than someone else with eczema, whose barrier is already open.

What are the eczema herpeticum symptoms I should never ignore?

Look for clusters of small, uniform blisters on eczema skin that burst to leave shallow, punched-out sores, together with burning or stinging pain rather than itch, rapid worsening over hours, fever, swollen glands and feeling generally unwell. The face and neck are common sites. The NHS lists eczema herpeticum as a rare but serious complication needing urgent medical attention, because antiviral treatment works best when started early and the infection can spread quickly.

Should I stop my steroid cream if my eczema looks infected?

Do not stop or change it on your own; ask the clinician who is assessing the infection. Uncontrolled inflammation is itself a driver of bacterial overgrowth, and stopping anti-inflammatory treatment abruptly can trigger a rebound flare. Whether to continue, pause or adjust depends on whether the infection is bacterial or viral and how extensive it is, and that judgment sits with your prescriber. Plain emollients are usually continued, ideally from a pump or clean spoon rather than a shared tub.

How long does infected eczema take to clear up?

For a typical bacterial infection treated appropriately, weeping and pain usually ease within the first couple of days, and the NHS notes impetigo generally clears within 7–10 days of starting treatment. Cellulitis improves more slowly over about a week. Eczema herpeticum stops forming new blisters within a few days of antiviral treatment and heals over one to two weeks. The eczema underneath often stays red and fragile for longer and needs continued care as directed.

Why does my eczema keep getting infected?

Recurrent infection usually points to a barrier that is not being maintained or inflammation that is not fully controlled, since both allow staph to colonize heavily. Some people, or their household members, carry staph in the nose and repeatedly reseed the skin. A clinician reviewing repeat infections may reassess the overall eczema plan, take nasal swabs, and discuss supervised measures to reduce bacteria on the skin. Repeated antibiotic courses alone rarely solve the pattern.

Can a child with infected eczema go to school or nursery?

For impetigo-type bacterial infection, NHS guidance is to stay away from school or nursery until 48 hours after treatment starts or until the crusts have dried, whichever is sooner, because the infection spreads by contact. A child with fever or who is unwell should stay home regardless. For eczema herpeticum, follow the specific advice of the treating clinician. Covering weeping areas with a clean dressing and separate towels at home reduce spread to siblings.
