Which condition is non-contagious and characterized by inflammatory skin symptoms such as erythema and itching?

• A. Scabies
• B. Atopic Dermatitis
• C. Impetigo
• D. Tinea

Answer: (B)

The key idea is identifying a non-contagious inflammatory skin condition that causes redness and itching. Atopic dermatitis fits this pattern: it’s a chronic inflammatory skin disease where the skin becomes red, very itchy, and often dry or thickened. It isn’t caused by an infection and isn’t spread from person to person, though triggers like irritants, allergens, dry skin, or stress can flare it up. This distinguishes it from the other options, which are contagious infections: scabies is caused by mites and spreads between people; impetigo involves contagious bacterial crusting sores; and tinea is a contagious fungal infection that creates ring-shaped patches.
