Infection Types on Skin – A Comprehensive Guide on Different Skin Infections and Their Symptoms, Causes, Treatment, and Prevention

The skin is the largest organ of the human body and serves as a protective barrier against external threats. Unfortunately, it is not immune to infections. There are various types of infections that can affect the skin, each with its own set of symptoms and treatment options.

One common skin infection is impetigo, which is caused by bacteria and is characterized by red sores that can break open and form a yellow crust. Another type of infection is boils, which are painful, pus-filled lumps that form under the skin. When a collection of pus forms deeper within the skin, it is called an abscess.

Dermatitis is another skin infection that causes inflammation of the skin. It can be caused by various factors, including allergies, irritants, and genetic factors. Folliculitis, on the other hand, is an infection of the hair follicles and can lead to red, inflamed bumps on the skin. Cellulitis is a more serious infection that affects the deeper layers of the skin, causing redness, swelling, and pain.
