Abdominal distension: an important feature in human parechovirus infection.

A total of 8 infants presenting with sepsis-like illness were diagnosed to have human parechovirus (HPeV) infection; of which, 5 had abdominal distension and 6 had an erythematous rash. A combination of abdominal distension and erythematous rash was observed in 4 infants. The abdominal symptoms can be very prominent and signs could be confused with acute surgical conditions. Although fever and central nervous symptoms are important features, a red rash with abdominal distension and a low C-reactive protein value and lymphocyte count can be clues to recognize this infection.
