Skin Infections

If you have an itchy rash that keeps spreading, crusted sores on a child's face, or blisters that keep returning to the same spot, you may be dealing with a skin infection. This page covers the fungal, bacterial and viral infections our dermatologists see most often in Pakistan. The organism causing the problem decides the treatment, so the first step is always a proper diagnosis, not a cream chosen at the counter. Venus Aesthetics runs doctor-led dermatology clinics at 8 branches across Lahore, Karachi, Islamabad, Faisalabad and Gujranwala.

Dermatology consultation Rs 3,500By appointment only. Aesthetic treatment consultations remain free.

What it is

Understanding Skin Infections

A skin infection happens when a fungus, a bacterium or a virus grows in or on the skin. These conditions are grouped by the organism responsible, because the organism decides the treatment. The fungal group includes tinea of the body, groin, feet and scalp (commonly called daad or ringworm), pityriasis versicolor, and cutaneous candidiasis in warm, moist skin folds. The bacterial group includes impetigo, which crusts and spreads quickly in children, and folliculitis, where hair follicles become inflamed and filled with pus. The viral group includes herpes simplex, herpes zoster (shingles) and molluscum contagiosum. Several of these mimic each other, and some mimic eczema, so the diagnosis has to come first.

Signs we treat

Come in if you recognise any of these

  • A round or oval itchy patch with a raised, scaly edge, often in the groin, under the breasts, on the thighs or across the trunk
  • Itching and peeling between the toes, or thick discoloured toenails that keep reinfecting the feet and groin
  • Pale or brown patches with a fine scale on the chest, back, neck or shoulders, more obvious after sun exposure
  • Red, sore, moist skin in body folds, under the tummy or between the fingers, sometimes with small spots scattered at the edge
  • Blisters or honey coloured crusts around the nose and mouth, usually in a child, spreading over a few days
  • Clusters of pus filled bumps around hair follicles on the beard area, scalp, legs, chest or back, often after shaving or waxing
  • A painful, burning band of blisters on one side of the body or face, or a tingling patch that blisters in the same place again and again
How we treat it

Your plan, step by step

1

Diagnosis before any prescription

The doctor examines the skin properly, including the feet, the nails and the skin folds, because the source of a rash is often somewhere the patient has not thought to mention. Where the picture is not clear, a skin scraping can be examined under the microscope, a Wood's lamp can be used, or a swab can be sent for culture. Fungal, bacterial and viral infections need completely different medicines, so guessing is what makes these problems drag on for months. Dermatology consultations at Venus Aesthetics are Rs 3,500 and by appointment.

2

Looking for what is feeding it

Heat, sweat and humidity through the Lahore, Karachi and Faisalabad summer keep fungal infections alive, and so do tight synthetic clothing, long hours in closed shoes, shared towels and gym benches. Uncontrolled blood sugar makes candidiasis and repeated folliculitis far more likely, so the doctor may ask about diabetes or request a test. An infection that keeps returning is usually being fed by something, and that something has to be named before the treatment can hold.

3

Treatment matched to the organism and the site

Topical treatment suits many limited fungal patches. Scalp and nail infections need oral antifungals, because creams do not reach the hair root or the nail bed. Impetigo needs an antibiotic, applied or taken by mouth depending on how widespread it is. Herpes simplex and herpes zoster need antivirals, and with these the timing matters as much as the medicine. Steroid containing combination creams are stopped, because they change how an infection looks and allow it to spread wider.

4

Breaking the reinfection loop

Treating the visible patch alone is why so many cases come back. Where it applies, the plan covers the feet and toenails, hot washing of clothes, towels and bedding, not sharing towels, razors or nail clippers, and getting affected family members seen rather than passing the cream around the house. For impetigo and molluscum contagiosum, we give clear advice on contact at home and at school.

5

Review, and finishing the course

You are asked to come back rather than judge the result yourself, because skin can look clear while the organism is still present. Treatment stops on the doctor's advice, not when the itching settles. If a long oral course is planned, the doctor may check your bloods before and during treatment. If the rash is not behaving as expected, the diagnosis is revisited and a scraping or swab may be repeated.

6

Being honest about the outcome

Most fungal and bacterial skin infections clear completely when the right treatment is finished properly. Herpes simplex is managed and controlled, not cured, and pityriasis versicolor often returns each summer, so a maintenance plan is discussed rather than promised away. Marks and colour changes left behind after an infection settles fade slowly, over weeks to months, and that part of healing is separate from the infection itself.

FAQs

Skin Infections, answered honestly

I have a round, itchy patch with a raised edge. Is this ringworm?
It may well be tinea, known locally as daad. Tinea usually forms a round or oval patch with a raised, scaly border and clearer skin in the centre, and it itches badly in heat. But eczema, psoriasis and skin already treated with a steroid cream can look very similar. A skin scraping examined under the microscope settles the question in clinic, and the answer changes which medicine you actually need.
Why does my fungal infection keep coming back after the cream finishes?
Usually for one of five reasons. The course was stopped when the itching settled rather than when the fungus cleared. Only the visible patch was treated, not the active border beyond it. The feet or toenails were never treated, so they keep reseeding the groin and body. Clothes, towels and bedding were not washed hot. Or someone else at home has it untreated. Recurrence is common, and it is fixable once the source is found.
What are the pale patches on my back, chest and shoulders?
Often pityriasis versicolor. A yeast that normally lives on everyone's skin overgrows in heat and humidity, which is why it appears through the Pakistani summer and monsoon months. The patches can be paler or darker than your own skin, carry a fine scale when scratched, and become more obvious after sun exposure. Treatment clears the yeast reasonably quickly, but the colour difference can take weeks or months to even out.
Can I just use the combination cream the pharmacy sold me?
Please stop before you do. Many creams sold over the counter here mix a strong steroid with an antifungal or an antibiotic. The steroid calms the itching for a few days, then the infection spreads wider, loses its usual shape and becomes much harder to recognise and treat. It can also thin the skin and leave stretch marks. Bring the tube with you so the doctor can see exactly what has been used.
My child has sores with a honey coloured crust near the nose and mouth. Should they stay home?
That description fits impetigo, a bacterial infection that spreads by touch and through shared towels. Keep your child at home until a doctor has seen them and treatment has started, and most schools will ask for the sores to be dry or covered before they return. Cut the nails short, keep hands washed, and do not share towels or bedding. Treatment is a prescribed antibiotic, applied or oral depending on how widespread it is.
My child has small pearly bumps that keep multiplying. What are they?
Most likely molluscum contagiosum, a harmless viral infection that is very common in children. The bumps are small, firm and dome shaped, often with a tiny dent in the centre, and they spread through scratching, close contact and shared towels. They do clear on their own, but that can take many months, and they can spread in the meantime. The doctor will discuss whether to treat or to wait, based on the number, the site and your child's age.
Can cold sores, genital herpes or shingles be cured?
Herpes simplex is controlled, not cured. After the first attack the virus stays in a nerve and can reactivate, so the aim is fewer, shorter and milder episodes. Antiviral tablets work best when started at the first tingle, and daily suppressive treatment is an option if attacks are frequent. Shingles is different: see a doctor within 72 hours of the rash appearing, and go the same day if it is anywhere near an eye.
How long does treatment take, and how do I book an appointment?
It depends on the organism and the site. A small patch on the body means a shorter course than a scalp or nail infection, which needs oral treatment for a longer period along with review. Your dermatologist will give you a realistic timeline once the diagnosis is confirmed, rather than a fixed number of days before it. Dermatology consultations are Rs 3,500 and by appointment only.
