An example of a general infection is which of the following?

• A. Syphilis
• B. Acne
• C. Flu
• D. Athlete's foot

Answer: (A)

A general infection is one that involves the whole body or multiple systems, not just a single localized area. The flu is a clear example because it spreads systemically and causes fever, fatigue, body aches, and other symptoms that affect the entire body, not just one spot. Acne and athlete’s foot are localized skin infections—acne affects a facial/skin area, and athlete’s foot stays on the feet. Syphilis can become systemic if untreated, but in everyday salon-safety contexts it’s typically discussed as an STI with potential systemic involvement rather than as a standard general infection example.
