Abstract

Japanese encephalitis had been one of the most serious endemic disease during summer time from 1949 to 1968 in Korea, but since 1969 it has markedly been decreased by the unknown factors.
However, Japanese encephalitis has still occurred in some areas and it was much concerned to the public as a endemic disease every year.
For these reasons, the present investigation was performed by using hemagglutination inhibition (HI) test (Clarke &: Casals, 1958). The total of 594 of human sera from the out-patients of St. Mary´s hospital were tested and 1, 008 fowl sera were collected in four different areas of Korea from July to November, 1975, respectively.
The following results were obtained.
1. The total 56.4% of the 594 cases were confirmed as a HI antibody and 58.3% in 278 male cases out of the 594 and 54.856/ of 316 cases the rate of female.
2. In the group whose age was from 41 to 50, it was 71.2% and this shows that it was markedly higher than others.
3. Seasonal distribution of HI antibody was shown to be 63.1% in 306 cases in September, 1975 but in other season it was to have a low.
4. The total 8.3% of the 1, 008 fowl sera were confirmed to have an antibody on the four areas.
5. Geographical distribution of antibody in the four fowl areas were different from each other, and Seoul areas is the highest as 9.8% in 634 cases.
6. Seasonal distribution of HI antibody in the fowls were shown to be 16.4% in 165 cases in August.
