Clinical study of hospitalized influenza patients during the 2001 to 2002 influenza season



Clinical study of hospitalized influenza patients during the 2001 to 2002 influenza season



Boei Ika Daigakko Zasshi 28(1): 1-5



We studied 20 children hospitalized with influenza between Dec. 1 2001 to Mar. 31 2002. Seventeen were diagnosed with influenza A, two with influenza B, and one with undetermined type; 13 were boys and seven were girls; 80% were either infants or less than five years old. Thirteen patients (65%) complicated with febrile convulsion. Acute encephalitis and encephalopathy occurred in two: those with encephalitis could neither stand nor speak. Fifteen patients (75%) including the two cases with acute encephalitis and encephalopathy were not immunized. The number of patients with severe neurological sequelae was significantly less among immunized patients than among non-immunized patients. This study suggested that the number of influenza patients with severe neurological sequelae could be reduced by annual influenza immunization in younger children.
