Introduction
Mortality was higher in infants with severe hepatitis (83%) than in infants with infection of the central nervous system (19%) (Modlin, 1986)
Hosts
Human
Transmission / Exposure Route
Person-to-person; the fecal-oral route is the predominant mode, although transmission sometimes occurs via respiration of oral secretions such as saliva. Indirect transmission occurs through numerous routes, including via contaminated water, food, and fomites (inanimate objects). Contaminated swimming and wading pools can also transmit the virus.[1]
Case Fatality Ratio
Deaths and other adverse consequences are rare and limited to patients with severe echovirus encephalitis or to persons with B cell-deficiency syndromes who develop persistent infection.[2]
