Erysipelas, a bacterial skin infection

What is erysipelas (orbánc)?

Although erysipelas itself is usually treatable with antibiotics, its consequences can be long-lasting. Recurrent, repeatedly returning infections are especially dangerous because over time they can cause permanent damage to the lymphatic system.

How does erysipelas develop?

Erysipelas is usually caused by bacteria called Streptococcus pyogenes. These bacteria enter your body through injuries, cracks or wounds in your skin. Minor cuts, abrasions, burns, wounds or even insect bites can serve as "entry points."

Healthy skin has a protective layer that prevents bacteria from entering. However, if the skin is damaged or the immune defense is weakened, this protective layer is compromised and bacteria can more easily invade.

Risk factors

Certain conditions significantly increase the risk of infection:

• Chronic lymphoedema or lipedema – stretched, swollen tissues have poorer circulation and reduced immune response
• Chronic venous insufficiency, leg ulcer – an open wound is a persistent entry point (home treatment with low-level laser may also be an option)
• Diabetes – reduced immune response and slow healing of small wounds
• Higher body mass index (BMI > 30) – increased skin-fold irritation, fungal infection in skin folds
• Fungal skin infection between the toes – a typical entry point often overlooked
• Previous erysipelas – after one episode, lymphatic damage increases the risk of recurrence
• Post-oncologic surgical state (especially breast cancer–related arm swelling – BCRL) – the lymphatic system is already compromised
• Older age, reduced general immunity

If any of the above risk factors apply to you, it is worth reviewing the leg swelling triage article for a symptom-based differential diagnosis.

How does erysipelas spread?

Patients commonly fear that family members might catch the infection. This fear is only partly justified. Erysipelas is not considered highly contagious. Direct contact with the bacterium is required, and it generally causes infection only if the skin's protective barrier is broken.

Put simply, a relative could catch erysipelas if they thoroughly touch your inflamed skin, stroke it, and then transfer the bacteria with their hand into a wound, eye or mouth on their own body. If, after touching your leg, they wash their hands thoroughly and disinfect them (e.g. with diluted household bleach), the chance of them catching the disease is minimal.

The pathogen is not airborne, so merely being in the same room with you does not transmit it. Direct contact with infected skin or secretions is necessary.

The symptoms of erysipelas

It most commonly appears on the lower limb, but can also occur on other areas such as the arms, buttocks, abdomen, and even the face. It is usually easy to recognize based on its symptoms.

• Redness: The affected area shows marked redness. Erysipelas does not remain at the entry point but begins to spread. The skin has a rich lymphatic network, and once bacteria enter the lymphatics they start to spread there. One characteristic sign is that the redness spreads upward along lymphatic channels from the entry point. Historically this was described as a "tongue-like" spread: the redness extends along certain lymphatic channels, with a narrower leading edge that widens toward the lower end.
• Swelling: The skin in the affected area swells and feels tight. This swelling may also be noticeable around the infected region.
• Warmth and pain: The skin may feel warm, and there can be tenderness and pain. Pain intensity varies and may increase with pressure or touch.
• Fever and systemic symptoms: Erysipelas is often accompanied by fever, which can be mild or high. Other general symptoms may include chills, headache, fatigue and muscle aches.
• Blisters or pustules: Small blisters may appear on the inflamed area containing clear fluid (lymph) or pus.
• Regional lymph node swelling: If the infection reaches nearby lymph nodes, they may become enlarged, tender and painful.

When is it urgent? – Red flags

If you have any of the following symptoms, you MUST go to the emergency department or an on-call clinic immediately:

• High fever (above 39 °C), especially with chills
• Rapid spread of redness (visibly advancing hour by hour)
• Blackish-purple discoloration on the infected area
• Severe, throbbing pain unusually intense for you
• Severe malaise, confusion, low blood pressure
• Nausea, vomiting, extreme weakness

These signs may indicate a severe complication — even sepsis (blood poisoning) — and may require hospital treatment with intravenous antibiotics.

Complications of erysipelas

Neglected erysipelas can lead to serious complications!

Sepsis (blood poisoning): Without treatment, or if the wrong antibiotic is given, bacteria can enter the bloodstream and cause severe sepsis, which can be life-threatening.

Skin problems: After erysipelas, residual changes such as discoloration, spots or scarring may remain on the skin.

Fasciitis necroticans: A rare but very severe complication in which the infection destroys deeper layers of tissue beneath the skin. It requires urgent surgical intervention.

Lymphoedema (also called lymphedema): As noted, the pathogens that cause erysipelas spread through and inflame lymphatic vessels. Scarring from this inflammation can damage, block or obstruct the lymphatics. Even a single episode of erysipelas can result in permanent lymphoedema. Recurrent erysipelas makes this outcome almost certain.

The lymphatic system's task is to remove lymph from tissues. Small lymphatic vessels collect it and pass it to larger vessels that lead to lymph nodes. Lymph nodes filter the lymph and remove cells and substances important for immunity. If inflammation from erysipelas destroys lymphatic vessels, the lymphatic system can no longer function normally, leading to edema (swelling).

Lymphoedema resulting from erysipelas is a permanent, not completely reversible condition — it can only be controlled with maintenance therapy. Clinical background: Lymphoedema — forms, causes and stages; home management protocol: Managing lymphoedema at home.

Chronic, recurrent erysipelas: because of the damaged lymphatic system, the infection is more likely to return. After one episode, the risk of a subsequent episode in the same limb is 2–3 times higher. Chronic, recurrent erysipelas (3+ episodes) typically leads to progressive lymphoedema.

What to do if you suspect erysipelas

See a doctor immediately (start with your GP, or a dermatologist). The sooner appropriate antibiotic treatment begins, the lower the risk of complications.

Erysipelas CANNOT be treated at home with folk remedies, soaking, nettle tea, or ointments!

If symptoms appear:

• Avoid exertion. Even muscle pumping from walking can promote the spread of the infection.
• Do not squeeze, massage or scratch the affected area, as this can rupture and spread the infection.
• Keep the affected area clean and dry.
• Do not apply anything to it, do not rub it! Wet dressings further soften the skin and help bacteria spread.
• Cool the area. Dry cooling (definitely not wet compresses) reduces inflammation and lowers skin temperature, which is unfavorable for bacterial growth and slows the spread of infection. By dry cooling I mean using a cold pack or even a bag of frozen peas, but do not place it directly on the skin — put a layer of towel between the skin and the cold source. This prevents skin from getting wet while allowing the beneficial cooling effect. Cooling sessions should last 10–15 minutes at a time. Prolonged cooling can cause frostbite-type skin injury.
• Do not let others touch the wound with bare hands. If they do, they should immediately wash their hands with soap and warm water and use a hand disinfectant, e.g. a household bleach solution.
• Do NOT use pneumatic compression (machine) therapy! During an active skin infection the treatment must be paused because pressure can "spread" the bacteria.
• Elevation: if you can elevate the affected limb (e.g. put your leg on a stool), it reduces swelling and pain.

Recovery time for erysipelas and treatment protocol

With appropriate treatment, erysipelas generally heals in 1–2 weeks, but this depends on several factors.

When you start taking antibiotics — the main therapeutic method — you may notice symptom relief within 2–3 days. Fever and malaise usually resolve within the first 48 hours, while the red, swollen area on the skin begins to fade within 7–10 days.

Rules for recovery

• Take the antibiotic prescribed by your doctor exactly as instructed.
• It is important to take the tablet at the same time each day to maintain an even blood level of the medication.
• Finish the full prescribed course even if you feel better! Early discontinuation can lead to relapse and antibiotic resistance.
• Rest a lot, especially during the first days, because your immune system works best when rested.
• Keep the infected area clean and dry! Do not apply wet dressings or soak it.
• If you have fever or pain, take antipyretics or pain relievers (paracetamol or ibuprofen, as advised by your doctor).
• Drink plenty of fluids — infection and fever increase fluid loss.

Contact a doctor if symptoms do not begin to improve after 3 days of correctly taken medication, or if new symptoms appear. Also seek medical help if the redness continues to spread or if your fever does not subside. In such cases the doctor may need to change the antibiotic or start intravenous therapy.

Because erysipelas tends to recur, pay attention to prevention even after complete recovery. Protect the skin from injury and promptly treat even minor wounds.

How can you prevent erysipelas from returning?

Once someone has had erysipelas, they are at increased risk of recurrence. Prevention rests on three main pillars: skin protection, maintaining good circulation, and in certain cases prophylactic antibiotic therapy.

Daily skin protection

• Daily skin care: use moisturizers, especially on dry, cracked areas (ankle, heel, between toes).
• Treat fungal infections between the toes immediately — this is the most common entry point for erysipelas. Antifungal cream + keeping the area dry + breathable socks.
• Immediate wound care: disinfect and dress even the smallest cuts or abrasions. Do not let them heal unattended.
• Careful handling of insect bites: especially for mosquito and tick bites, disinfect after scratching.
• Shoe and sock hygiene: alternate, wash and use breathable materials to reduce fungal infection risk.
• Care with manicures/pedicures: avoid excessive cutting around the nails that may cause injury.

Supporting circulation

• Wear compression stockings — particularly recommended in chronic venous insufficiency, previous erysipelas, lymphoedema or lipedema.
• Regular exercise while wearing compression garments — swimming, walking, cycling.
• Pneumatic compression — in lymphoedema or chronic swelling, maintenance IPC therapy during infection-free periods can help stabilization.
• Weight control — higher BMI worsens venous and lymphatic circulation and skin integrity.

Prophylactic antibiotic therapy

In recurrent erysipelas (2+ episodes per year) a physician may prescribe long-term, low-dose prophylactic antibiotics. This is typically a 6–12 month seasonal or continuous course (usually a penicillin derivative). Clinical trials show this can reduce recurrence risk by 50–60%. Discuss this option with your GP or dermatologist.

Recurrent erysipelas – what to do long-term?

Recurrent erysipelas is not accidental. Although the bacteria are cleared from your body, the lymphatic system remains weakened — making subsequent infections easier to establish. The following protocol can reduce recurrence risk:

1. Weekly self-examination: check your legs and arms for new wounds, redness or fungal infection.
2. Comprehensive specialist consultation: combined dermatology and lymphology assessment is particularly useful for recurrent cases.
3. Blood and tissue sampling: if the infection is particularly persistent, identification of the pathogen and antibiotic susceptibility testing may be necessary.
4. Lifestyle analysis: what caused the entry? Shoes, sport, foot care, fungus? Eliminating causes is the best prevention.
5. Daily wear of compression garments: compression reduces swelling tendency, which reduces skin tension and the risk of injury.
6. Consideration of prophylactic antibiotics: for 3+ episodes/year, medical consultation about long-term low-dose prevention is highly recommended.
7. Stage assessment by lymphoedema stage: if recurrent erysipelas has led to lymphatic damage, ISL staging underpins long-term maintenance therapy.

Clinical evidence linking erysipelas and lymphoedema

Recent decades of clinical research clearly support the relationship between erysipelas and the lymphatic system.

The clinical message is clear: alongside rapid antibiotic treatment, long-term prevention (skin care, compression, lifestyle) is equally important. A single episode of erysipelas can cause permanent lymphatic damage, so prevention can avert future episodes.
