How is impetigo primarily spread?

Correct answer: A. Direct skin-to-skin contact

• A. Correct. Impetigo spreads primarily through direct contact with the infected skin lesions or nasal discharge of an infected person. The bacteria are transferred when someone touches the lesions and then touches their own skin.
• B. Impetigo is a superficial skin infection — it is not bloodborne.
• C. Impetigo is not transmitted by airborne droplets — it requires direct contact with infected lesions.
• D. While fomites (contaminated towels, clothing) can theoretically spread impetigo, direct contact is the primary route.
