What are the three main categories of infectious skin disorders?

• A. Parasitic, autoimmune, and allergic.
• B. Viral, parasitic, and allergic.
• C. Bacterial, fungal, and autoimmune.
• D. Bacterial, viral, and fungal.

Answer: (D)

Infectious skin disorders are caused by living microorganisms, and the most common groups of these pathogens that affect the skin are bacteria, viruses, and fungi. This classification covers the major ways skin infections arise: bacterial infections like impetigo or cellulitis; viral infections such as herpes simplex or varicella-zoster; and fungal infections including dermatophytoses (tinea) and candidiasis. Parasites can also cause skin problems, but when listing the primary infectious etiologies taught in many health courses, bacteria, viruses, and fungi are the three main categories.
