Ringworm Rash: Spotting It, Treating It, Stopping the Spread
Despite the name, there’s no worm — ringworm is a fungal skin infection that forms an itchy, scaly, ring-shaped patch with a raised edge and clearer centre. It spreads by skin contact, gym mats, towels and pets, and it responds well to the right antifungal — while the wrong cream makes it quietly worse. A registered Irish doctor can confirm it by video for €34.99 and get treatment started today.

One certificate per consultation
A sick note and a fit-to-work certificate certify opposite things — that you are unfit for work, and that you are fit to return. Each needs its own clinical assessment, so they cannot both be issued from the same consultation. If you need both, please book two separate appointments. Booking this consultation intending to obtain both does not entitle you to a refund.
A round or oval patch that grows outward, with a scaly, slightly raised red edge and calmer centre.
Itchy, sometimes with small bumps or blisters along the ring’s border.
One patch or several; body, arms, legs, groin (“jock itch”) and feet (athlete’s foot) are all the same family of infection.
Common sources: skin-to-skin contact and contact sports, shared towels and gym equipment, and cats, dogs and other pets — kittens especially.

Treatment
Body ringworm: an antifungal cream — terbinafine or clotrimazole/miconazole — applied to the patch and a couple of centimetres beyond it, continued for 1–2 weeks after the skin looks clear (stopping early is the classic relapse cause).
Widespread, stubborn or recurrent infection: antifungal tablets, which a doctor can prescribe after assessment.
Scalp ringworm — scaly patches with broken hairs or patchy hair loss, mostly in children — always needs oral treatment; creams cannot reach the hair root. This one genuinely needs a doctor.
Wash bedding and towels hot, don’t share them, and check/treat pets showing scaly patches (a vet visit for the likely culprit kitten saves the whole household).
The steroid-cream trap: putting a plain steroid cream (or a leftover combination cream) on ringworm calms the redness while the fungus spreads underneath — creating a hard-to-recognise, harder-to-treat rash called tinea incognito. If a rash improved on steroid cream then came back worse or wider, stop and get it reviewed. And a rapidly spreading, hot, painful rash with fever isn’t ringworm — that’s possible cellulitis and needs same-day care.
Gyms, mats and dressing rooms: cover patches during contact sports (and sit out mat sports until 48 hours of treatment is done), wipe shared equipment, wear flip-flops in communal showers, and keep your own towel strictly your own.

Frequently asked questions
Is ringworm caused by a worm?
No — it’s a fungal infection (tinea). The “ring” describes the shape of the rash; the same fungi cause athlete’s foot and jock itch.
How long is ringworm contagious?
Until treatment has been underway for about 48 hours. Until then avoid skin contact, don’t share towels or bedding, and cover the patch where practical.
How long until it clears?
Itch usually settles within days of starting an effective antifungal; the patch fades over 2–4 weeks. Keep applying the cream for 1–2 weeks after the skin looks normal or it tends to return.
My child has a scaly bald patch — is that ringworm?
Possibly scalp ringworm, which is common in children and always needs oral antifungal treatment prescribed by a doctor — creams don’t work on the scalp. It’s worth a prompt consultation.
Could my pet have given it to me?
Very possibly — kittens, cats and dogs carry ringworm, sometimes with only subtle scaly patches. If the family keeps catching it, a vet check for the pet is part of the cure.
I used a steroid cream and it’s worse — why?
Steroids suppress the redness while letting the fungus spread — the rash then rebounds larger and less typical (tinea incognito). Stop the steroid and get the rash assessed; it usually needs a proper antifungal course, sometimes tablets.
