What Are Common Causes of a Skin Rash?
Skin rashes can be caused by a variety of factors, ranging from allergic reactions to infections and underlying medical conditions. One of the most common causes is allergic contact dermatitis, which occurs when the skin reacts to substances like certain metals, plants (such as poison ivy), or chemicals in personal care products. Infections, both viral and bacterial, are also frequent culprits. Viral infections such as chickenpox or measles can lead to characteristic rashes, while bacterial infections like impetigo or cellulitis can cause red, inflamed skin. Fungal infections, such as ringworm or athlete’s foot, also result in rashes that often involve itching and scaling.
Other potential causes of skin rashes include autoimmune diseases such as lupus or psoriasis, which cause inflammation and abnormal skin cell turnover. Eczema, a condition characterized by dry, itchy, and inflamed skin, is another common cause. Rashes can also be triggered by medications or certain environmental factors, such as heat or sweat, leading to conditions like heat rash. It is important to identify the underlying cause of a rash to determine the most appropriate treatment and avoid potential complications, especially in cases where an infection or allergic reaction is involved.
