Skin Infection Treatment in Phuket: Cellulitis, Infected Cuts and Fungal Rashes
Clinically reviewed by Dr. Ponlawat Pitsuwan, Physician, Takecare Clinic Phuket. Last reviewed: September 2026.
“In Phuket, skin infections follow the holiday: a coral scrape while snorkelling, a scooter graze on the way back from dinner, or a scratched mosquito bite, all kept wet by sea water, sweat and humidity for days. A cut that would heal quietly at home can turn into spreading cellulitis here within a day or two. The earlier we see it, the simpler the treatment. We also see a steady stream of itchy fungal rashes in skin folds, which rarely clear with whatever cream was bought first.” Dr. Ponlawat Pitsuwan
What causes skin infections in a tropical climate
Healthy skin is a barrier that keeps bacteria and fungi out. Any break in it, from a cut, graze, blister, bite or patch of eczema, lets germs that normally sit harmlessly on the skin get inside. The two bacteria behind most skin infections are Staphylococcus aureus (“staph”) and Streptococcus pyogenes (“strep”). Heat, sweat and constant moisture soften the skin and slow healing, while sea water, sand and swimming pools add their own bacteria. Diabetes, poor circulation, swollen legs and a weakened immune system all raise the risk.
Cellulitis
Cellulitis is a bacterial infection of the deeper layers of the skin and the fat beneath it. It causes an area of skin that is red (or darker on brown and black skin), hot, swollen and tender, usually on the lower leg, and it tends to spread over hours to days. You may feel feverish and generally unwell. It is not contagious from person to person.
Impetigo
Impetigo is a superficial, very contagious skin infection, most common in children, that often starts in a scratched bite, cold sore or patch of eczema. It forms red sores that burst and leave golden, honey-coloured crusts, usually around the nose and mouth or on the arms and legs. Children are contagious until the sores have crusted over and healed or until 48 hours after starting treatment.
Infected coral cuts and road rash
Coral cuts are often deeper and dirtier than they look, because tiny fragments of coral, sand and marine bacteria are pushed into the skin. They are prone to slow healing, prolonged inflammation and infection. Road rash from a scooter fall grinds grit, tarmac and clothing fibres into a wide raw area. Both need thorough cleaning; debris left behind is the most common reason these wounds become infected or leave “tattoo” marks.
Fungal infections in the humidity
Fungi thrive in warm, damp skin. Tinea (ringworm) causes a ring-shaped, scaly, itchy rash with a clearer centre, on the body, groin (tinea cruris, “jock itch”) or between the toes (athlete’s foot). Intertrigo is inflammation in skin folds such as under the breasts, in the groin or between the buttocks, where skin rubs and stays wet, and it is often complicated by Candida yeast, which causes a bright red, moist rash with small satellite spots. Pityriasis versicolor, caused by a yeast called Malassezia, produces pale or pinkish-brown patches on the chest and back that become more obvious after a tan.
Vibrio vulnificus: the sea-water infection that is an emergency
Vibrio vulnificus is a bacterium that lives naturally in warm sea water and brackish water, especially where rivers or mangroves meet the sea. It is rare, but if it gets into an open wound, or a new cut made while in the sea, it can cause a rapidly spreading, severe infection within 12 to 72 hours: intense pain, swelling, dark red or purple skin, and large blood-filled blisters, often with fever and low blood pressure. It can progress to necrotising fasciitis (infection destroying tissue under the skin) and bloodstream infection. People with liver disease, heavy alcohol use, diabetes, a weakened immune system or iron overload are at highest risk. This needs a hospital emergency department immediately, not a clinic visit.
| Infection | What it looks like | Usual treatment |
|---|---|---|
| Cellulitis | Spreading red, hot, swollen, tender skin, often on a leg | Oral antibiotics such as flucloxacillin or cefalexin; IV if severe |
| Impetigo | Sores with golden, honey-coloured crusts | Antiseptic or antibiotic cream; oral antibiotics if widespread |
| Abscess or boil | Painful, swollen lump that feels soft or fluid-filled | Incision and drainage under local anaesthetic; antibiotics in some cases |
| Tinea or intertrigo | Itchy scaly rings, or red moist rash in skin folds | Antifungal cream such as terbinafine, clotrimazole or miconazole; keep dry |
| Suspected Vibrio or necrotising infection | Rapid swelling, severe pain, dark or blistered skin after sea exposure, fever | Emergency hospital care: call 1669 |
How we diagnose and treat skin infections at Takecare
The doctor examines the skin, asks how and where the wound happened (sea, freshwater, road, animal), checks your temperature, pulse and blood pressure, and feels for swollen lymph glands. We mark the edge of any redness with a skin pen, which makes it easy to judge over the next 24 to 48 hours whether treatment is working. Where it helps, we take a swab for culture to identify the bacterium and which antibiotics it responds to, or scrape a scaly rash to look for fungus. Blood tests are used when you have a fever or feel unwell. In most cases the diagnosis is clear at the first visit, so treatment starts the same day.
Uncomplicated cellulitis is treated with oral antibiotics aimed at staph and strep, commonly flucloxacillin or cefalexin, with clarithromycin, doxycycline or clindamycin for people allergic to penicillin; the usual course is 5 to 7 days, longer if it is slow to settle. Wounds from sea water may need an antibiotic that also covers marine bacteria. Impetigo that is limited to a small area can be treated with an antiseptic cream such as hydrogen peroxide 1% or an antibiotic cream such as fusidic acid, with oral antibiotics for widespread sores.
An abscess, a pocket of pus under the skin, usually needs to be opened and drained under local anaesthetic; antibiotics alone often fail because they cannot reach the pus. Infected coral cuts and road rash are cleaned thoroughly with irrigation, debris is removed, and the wound is dressed with non-stick dressings, with follow-up dressing changes. Fungal infections are treated with antifungal creams for two to four weeks, continued for a week or two after the rash has gone, and occasionally with antifungal tablets. We check tetanus vaccination for every open wound.
When to see a doctor
See a doctor the same day if redness is spreading beyond a pen line within a few hours, a wound is becoming more painful after the first two days, you see pus or a painful lump, red streaks run up the limb, or you have a fever or chills. Infections on the face, around the eye, on the hands or over a joint need prompt care, as do any skin infections in people with diabetes, a weakened immune system or poor circulation. Come back if you are not clearly better after 48 hours of antibiotics.
Go directly to a hospital emergency department, or call 1669, if pain is far worse than the appearance of the skin suggests, the skin turns dusky, purple or black, large blood-filled blisters appear, the area is spreading visibly by the hour, or you feel confused, faint, breathless or very unwell. These can be signs of necrotising fasciitis, Vibrio vulnificus infection or sepsis, and they need hospital treatment and often surgery.
Prevention and early detection
Clean every cut, graze and coral scrape the same day with clean running water and soap, remove any visible debris, and cover it with a waterproof dressing. Wear reef shoes and a rash vest when snorkelling over coral. If you have an open wound, especially a fresh one, stay out of the sea, lagoons and river mouths until it has closed; this matters most if you have liver disease, diabetes or a weakened immune system, because of the Vibrio risk. Wear a helmet, long trousers and closed shoes on a scooter, which prevent most road rash.
For fungal infections, dry thoroughly between the toes and in skin folds after swimming and showering, change out of wet swimwear and sweaty clothes promptly, choose loose cotton clothing, and do not share towels. Early detection is simple: look at any wound every day. Increasing pain, redness or swelling after the second day is the signal to see a doctor.

All three Takecare clinics are open 24 hours a day, 7 days a week, and you can walk in without an appointment. Come to Takecare Clinic Bangtao (Cherngtalay) near Laguna and Bangtao Beach, Takecare Clinic Kata-Karon on Kedkwan Road, or Takecare Clinic Patong on Prachanukroh Road. Most visits take under 30 minutes; abscess drainage takes a little longer. Antibiotics, dressings and creams come from our on-site pharmacy.
If a swollen leg makes it hard to walk, a doctor can come to your hotel or villa anywhere in Phuket, day or night, and we can arrange follow-up dressing changes. Message us a photo on WhatsApp or call 081-718-9080.
We confirm the price on WhatsApp before your visit, offer direct billing with most travel insurers, and provide a medical report and itemised receipt for your claim. If we find signs of a severe infection, we arrange referral to a hospital specialist.
Related services and treatments
Many skin infections start with something else. Scratched sandfly and mosquito bites are a common cause, and our page on insect bite treatment explains how to stop them getting infected. Broken blisters from a bad burn can also become infected, so early sunburn treatment helps, and a jellyfish welt that turns hot and weepy days later may need antibiotics as well as jellyfish sting treatment.
Scratching from scabies frequently leads to impetigo, so if the itch is worst at night, read about treating scabies in Phuket. A painful band of blisters on one side of the body is more likely shingles, covered on our shingles treatment page. If you cannot get to us, book a doctor hotel visit in Phuket, or see a walk-in doctor in Phuket at any branch.
Summary
Skin infections are common in Phuket because heat, sweat, sea water and sand keep small wounds wet and dirty. Cellulitis causes spreading red, hot, painful skin and needs antibiotics; impetigo causes honey-coloured crusts; abscesses usually need drainage; fungal rashes need the right antifungal and dry skin. Rapidly worsening pain, dark or blistered skin after sea exposure, or feeling faint and confused is an emergency that needs 1669 and a hospital. Takecare Clinic Phuket treats skin infections around the clock in Bangtao, Kata and Patong, or at your hotel.
“Draw a line around the redness with a pen before bed. If it has crossed the line by morning, or the pain is worse, come in that day. That simple check catches cellulitis while it is still a tablet problem rather than a drip problem.” Dr. Ponlawat Pitsuwan
Frequently asked questions
How do I know if a cut is infected?
Some redness and tenderness around a cut is normal in the first day or two. Infection is more likely if pain, redness, warmth or swelling increase after that, if the redness spreads outward, if pus or a cloudy discharge appears, or if you develop a fever or red streaks up the limb. Coral cuts and scooter grazes are especially prone to infection and are worth checking early.
Do abscesses need antibiotics or drainage?
Most abscesses need drainage. The doctor numbs the skin with local anaesthetic, makes a small cut to let the pus out, cleans the cavity and dresses it, which usually brings rapid relief. Antibiotics on their own often fail because they cannot reach the pus. They are added when there is surrounding cellulitis, fever, a weakened immune system or an abscess on the face or hand.
Can I swim with a skin infection or open wound?
It is best to stay out of the sea, lagoons and swimming pools until an open wound has closed and any infection is clearly improving. Sea water can carry bacteria such as Vibrio vulnificus, which rarely causes a severe infection in open wounds, particularly in people with liver disease or diabetes. Impetigo is contagious, so children should avoid shared pools until they are no longer infectious.
Can I walk in for skin infection treatment without an appointment?
Yes. All three Takecare branches in Bangtao, Kata and Patong accept walk-ins 24 hours a day, and you are usually seen within minutes by an English-speaking doctor. Most skin infections are assessed and treated in one visit, with antibiotics or antifungals from our pharmacy. You can send a photo on WhatsApp first if you want us to expect you.
Can a doctor treat a skin infection at my hotel?
Yes. Our doctors visit hotels and villas anywhere in Phuket, day and night. The doctor can examine the infection, mark its borders, start antibiotics, clean and dress wounds, and arrange follow-up dressing changes in your room. If the infection looks severe, the doctor will arrange hospital transfer.
Will my travel insurance cover skin infection treatment?
Most travel insurance policies cover treatment for infections and wounds that start during your trip, including follow-up dressings. We offer direct billing with most travel insurers and provide a medical report and itemised receipt if you need to claim yourself. Scooter injuries may be excluded if you had no valid motorcycle licence or helmet, so check your policy wording.
