Background: A rash is a skin condition that can cause redness, itching, or bumps. Rashes can be caused by a variety of factors, including allergies, infections, and irritants.

Causes: Common causes of rashes include:

• Allergies: Allergic contact dermatitis, urticaria (hives), and atopic dermatitis (eczema) are all caused by allergic reactions.
• Infections: Viral, bacterial, and fungal infections can cause rashes.
• Irritants: Contact with irritants can cause irritant contact dermatitis.
• Medications: Some medications can cause rashes as a side effect.

Susceptible Patient Groups: Anyone can develop a rash, but people with sensitive skin or a history of allergies are more prone to them.

Complications: Untreated rashes can lead to:

• Infection: Rashes can become infected.
• Chronic skin conditions: Some rashes can develop into chronic skin conditions.

Treatments: The treatment for a rash depends on the underlying cause. It may involve:

• Topical medications: Corticosteroids, antihistamines, or antifungal medications can be used to treat rashes.
• Oral medications: In some cases, oral medications may be necessary.
• Avoiding irritants: Identifying and avoiding irritants can help prevent rashes.
