Abstract


A status parasite infection on 3100 patients of Chonnan National University Hospital located in Kwangju City was studied with the purpose of epidemiolgical analysis. The data obtained from medical records of those patients, who had been registered (for admission and out patients clinics) and stool examined during the period between January 1, 1964 to August 31, 1969.
The results obtained are as follows
1. The overall prevalence of parasite infection among the patients was 81.5%, regardless of the species of parasite.
2. The most common parasites in this particular area were A. lumbricoides and T. trichiurus: A. lumbricoides with 59.4% of prevalence, 49.5% for T. trichiurus, 8.9% ofr C. sinensis, 3.9% for P. westermani, 2.7% for E. histolytica, 2.1% for Taenia spp., 1.4% for E. vermicularis, 1.2% for T. orientalis,, 0.2% for H. nana, 12.8% for A. duodenale.
3. The frequency of multiple infection, A. lumbricoides 59.4% state of infection with more than one species for an individual, decreased as the number of species increased; the frequency of infection by singie species was 48.8%, by two species 39.9%, by three species 9.7%, by four species 1.5%, and by five species 0.03%. IN two species infection, the most common combination was made of A. lumbricoides and T. trichiurus.
The multiple infection occurred more friquently in female than in male.
4. Prevalence of the parasite infection by geographical area was higher in West Coast Region with 86.4% prevalence and lower in Kwangju City, 77.6%. C. sinensis had the highest prevalence in Plain Region and South Coast Region along Young San River.
5. Farmers were infected most frequently (98.7), and the least for clerical workers (65.0%) among other occupations.
6. T he prevalence of parasite infection showed that the higher education the lower rate of the infection; the group with no formal education showed the highest rate, 89.4%, where as the group with higher education (callege graduate or higher) had the lowest rate, 15.0%.
7. The parasite infection rate by year showed decreasing trend as year passes, even though it is not so remarkable; in 1964 the rate was 89.4% whereas 65.2% in 1969.
8. The age specific infection rate was the highest for 40-49 year age group and the lowest for under one year age group. Older age groups (after 70 year) had generally lower infection rate than younger ages (agter 15 year) of age.
9. Correlation between the parasite infection and the primary diagnosis was not found.
