A clinical observation and statistical management on 592 cases of epidemic encephalitis
admitted to the department of pediatrics, Chonnam University Hospital with 10 years duration
from 1971 to 1980 were carried out. The following results are obtained:
1) No periodical change was observed in annual incidence during these 10 years.

(74.6%), particularly those in rural districts (89.9%), were seen between mid-August and mid-September.
3) Number of patients by age group was highest from 6 to 10. The ratio of male to female patients was 2.1 : 1.
4) Chief complaints on admission were fever (98.8%), neck stiffness (73.0%), Kernig sign (70.4%),
headache (59. 0%), vomiting (58.3%).
5) In most cases (76.3%), peripheral leukocytosis with increased polymorphocyte was noted. Hyponatremia
was observed in 47.5%, and S-GOT was elevated in 57.1%.
6) Findings of C.S.F.: Pleocytosis (81.3%), increased protein content (90.1%), normal or -slightly increased sugar
content (96.2%), and normal chloride level (83.7%).
