Rash associated with erythema infectiosum (fifth disease) is characterized by what facial rash?

• A. Maculopapular trunk rash
• B. An erythematous slapped-cheek facial rash
• C. Vesicular rash
• D. Petechial rash

Answer: (B)

The key feature here is the distinct facial rash of erythema infectiosum: a bright red, erythematous cheek appearance described as a slapped-cheek rash. This facial redness is classic for parvovirus B19 infection in children, often with a pale circumoral area and later a lace-like rash on the trunk and limbs. The other rash patterns don’t fit this presentation: a maculopapular trunk rash is nonspecific, a vesicular rash suggests varicella or herpes, and a petechial rash points toward other causes like thrombocytopenia or meningococcemia. The slapped-cheek facial rash is the hallmark clue for erythema infectiosum.
