title: Fatal echovirus type 11 infections.
abstract: Two infants with fatal echovirus type 11 infections are described. Disseminated intravascular coagulation developed in both patients, and at postmortem examination, diffuse hemorrhagic necrosis of multiple organ systems was evident, most strikingly in the liver. A 3-month-old child is described, in whom lethargy, vomiting, pitting edema of the occipital scalp and neck, and subsequent diffuse echovirus disease developed. The clinical manifestation in this infant of focal myositis with histologic documentation at postmortem examination is unique to echovirus 11 disease. To our knowledge, this child represents the first described patient with nonparalytic, fatal echovirus type 11 infection occurring beyond the immediate neonatal period.
