Which of the following is considered a contagious skin condition?

Scabies is a highly contagious skin condition caused by a mite that burrows into the skin, leading to intense itching and a rash. It spreads easily through close personal contact, making it particularly infectious within families, crowded living conditions, or among people who share personal items like clothing or bedding.

The other conditions mentioned, while they may cause skin irritation or discomfort, are not transmitted from person to person. Contact dermatitis is typically a reaction to an allergen or irritant, eczema is usually linked to genetic and environmental factors, and psoriasis is a chronic autoimmune condition. These conditions can cause distress but do not have the same contagious properties as scabies. Understanding the transmission methods of skin conditions is essential for effective prevention and treatment strategies.
