Which of the following conditions is a systemic disease caused by Staphylococcus?
a. Impetigo
b. Folliculitis
c. Carbuncle
d. Toxic shock syndrome

검증된 단계별 안내

Step 1: Understand the difference between localized and systemic infections. Localized infections affect a specific area of the body, while systemic infections spread throughout the body, affecting multiple organs or systems.
Step 2: Review each condition caused by Staphylococcus: impetigo, folliculitis, and carbuncle are primarily localized skin infections, meaning they affect specific areas of the skin.
Step 3: Recognize that toxic shock syndrome (TSS) is a systemic condition caused by toxins produced by Staphylococcus aureus, which can enter the bloodstream and affect multiple organs.
Step 4: Identify that among the options, toxic shock syndrome is the systemic disease because it involves widespread effects beyond the initial site of infection.
Step 5: Conclude that the correct answer is the condition that represents a systemic disease caused by Staphylococcus, which is toxic shock syndrome.

Localized vs. Systemic Infections

Localized infections affect a specific area of the body, such as the skin, while systemic infections spread throughout the body, affecting multiple organs or systems. Recognizing the difference is crucial for identifying diseases like toxic shock syndrome, which is systemic, versus skin-limited conditions like impetigo.

Toxic Shock Syndrome (TSS)

Toxic shock syndrome is a severe, potentially life-threatening systemic illness caused by toxin-producing strains of Staphylococcus aureus. It involves sudden fever, rash, low blood pressure, and multi-organ involvement, distinguishing it from localized skin infections.
