Dermatitis is a general term to describe several types of skin irritations and rashes that may be caused by allergies, infections, irritating substances, genetics, an overactive immune system, and more. It is a common condition that is usually characterized by dry, red, swollen or itchy skin. However, a more serious condition may result in oozing skin blister, crusty scales, painful cracks or flake off.
Fortunately, dermatitis is not contagious, but it can, however, make a person feel uncomfortable and self-conscious. Certain types of dermatitis can last a long time, while others may flare up, depending on the season, what you’re exposed to, or stress. The most common ones include atopic dermatitis, contact dermatitis, dyshidrotic dermatitis, and seborrheic dermatitis.
Avoid scratching the affected area as you can open or reopen wounds and spread the infection.
