Red flags & when to go in person for Fungal Skin Infection (Ringworm)

Audience: adult

Fungal skin infections, commonly known as ringworm, are caused by fungi that affect the skin, scalp, or nails. They often appear as red, itchy, circular rashes with clearer centers. Many cases can be managed through telemedicine by discussing symptoms, showing affected areas via video, and receiving guidance on treatment. However, some situations require in-person evaluation to ensure proper care. This guide helps you recognize warning signs that mean you should see a healthcare provider in person. It also explains what telemedicine can and cannot do for fungal infections, how to prepare for a virtual visit, and what to expect afterward. Remember, this information is for education and triage only and does not replace a physical examination or personalized medical advice.

Red flags — go in person / ER

• Rapidly spreading or worsening rash despite treatment — seek in-person care immediately.
• Presence of fever, severe pain, pus, or swelling indicating possible secondary infection — go to a healthcare facility.
• Scalp involvement with hair loss or thick crusts — requires physical examination and specialized treatment.

What telemedicine can do

• Initial assessment of typical ringworm rash via video.
• Providing guidance on antifungal treatment and skin care.
• Monitoring mild cases with patient-reported progress.

What telemedicine cannot do

• Diagnosing complicated or unusual rashes without in-person exam.
• Managing severe infections with systemic symptoms like fever.
• Treating infections involving scalp hair loss or nail involvement without physical assessment.

What is a Fungal Skin Infection (Ringworm)?

Ringworm is a common fungal infection that affects the skin, scalp, or nails. It is not caused by worms but by fungi that thrive in warm, moist areas. The infection often appears as round or oval red patches with raised edges and clearer centers. It can cause itching and discomfort but is usually treatable with antifungal medications.

When to Use Telemedicine for Ringworm

Telemedicine can be helpful for initial evaluation of ringworm. You can show the rash via video, describe your symptoms, and get advice on treatment options. Many uncomplicated cases respond well to topical antifungal creams or oral medications prescribed remotely.
