Where can herpes simplex virus infections appear?

• A. Lungs and kidneys
• B. Infection of the mouth, skin, eyes, and genitals, especially in immunocompromised individuals
• C. Heart and bones
• D. Blood and lymph nodes

Answer: (B)

Herpes simplex virus infections most often present on mucocutaneous surfaces—mouth and lips, skin, eyes, and the genital area. This pattern comes from how the virus establishes latency in sensory nerves and can reactivate to produce vesicular lesions at these exposed mucosal sites. In people with weakened immune systems, these infections can be more extensive or widespread, but the classic appearance remains mucocutaneous. Other sites like the lungs, kidneys, heart, bones, blood, or lymph nodes are not typical first-line locations for HSV infections, though rare disseminated cases can involve internal organs under specific conditions.
