What term describes a contagious bacterial infection of the skin that leads to clusters of blisters?

• A. Folliculitis
• B. Impetigo
• C. Psoriasis
• D. Eczema

Answer: (B)

The term that describes a contagious bacterial infection of the skin, characterized by the formation of clusters of blisters, is impetigo. This skin condition is primarily caused by bacteria such as Staphylococcus aureus or Streptococcus pyogenes. Impetigo commonly manifests as red sores on the face, especially around the nose and mouth, which can quickly rupture, ooze, and form a yellowish crust.

In contrast, folliculitis refers to the inflammation of hair follicles, typically leading to small pimples or pustules, but it does not involve blistering clusters associated with a bacterial infection like impetigo. Psoriasis is a chronic autoimmune condition that results in thick, red patches covered with silvery scales and is not infectious. Eczema, also known as atopic dermatitis, is a non-contagious skin condition that causes dry, itchy skin and may lead to oozing, but it is not primarily characterized by blister formation as seen in impetigo. Thus, impetigo is the correct term for the described skin condition.
