¿ä¾à ¥° . Epidemiological study of leprosaria and leprosy colonies:
The epidemiological study was made during the period of full 5 years from October
1956 to September 1961 in the inmates of 4 leprosaria and 35 leprosy colonies in Yeong
Nam area (Kyong Buk £¦ Kyong Nam provinces). The total inmates taken for thIns
study are 7,305 (6,281 leprosy patients and 1,024 non-infected children or healthy
persons), and the results are as follows:
1. The distribution of the patients by their birth places shows that great portion of
them were born at the lower valleys of Nak Dong River and its tributaries. The
average rate is 0.8 per 1,000 persons in Kyong Buk Province and 0,7 in Kyong Nam
Province. And the majority of the others who were born in other provinces were in Ho
Nam area (Cholla Bukdo and Cholla Namdo provinces) which is neighbouring with
Yeong Nam area.
2. With respect to sexes, the ratio male to female is 1.4 to 1, but it shows a
decreasing delimitation of the difference between them when the patients are in
before-puberty or after-menopause. Their age groups show 16.99% in 25-29 years,
16.56% in 30-34 years, which are the highest. And the group of 20-49 years of age
occupies 79% of the whole patients, and that of 0-19 years of age 12% and only 9% is
the group of old ages.
3. The onset-ages show 31.08% in 15-19 years of age, and 20-24 years, 10-14 years,
25-23 years in order. The lowest onset-age is 2 years and 3 months, and the highest
on-set-age is 73 years. As for the initial lesion, 25.6% appears in the lower legs and
22.0% in the forearms. The initial lesions are found in the exposed extremities which
get mechanical contacts mostly. On the contrary, the lesions are found seldom in the
upper arms and thighs.
4. As for the type of the disease, lepromatous type is predominant occupying 60.1%.
Tuberculoid type is 35.3%. And the ratio between the two types is 1.7 to 1.
Indeterminate group is 4.4% and borderline group is 0.2%. As for their stages in the
disease, majority of them are light cases, and the others are in such order, moderate
and severe cases. Among the severe cases, 11% is lepromatous type and 7% tuberculoid
type.
5. Duration of the disease after onset until admitted to leprosaria or colonies -53.8%
less than 5 years, 41.3% less than one year among those of less than 10 years duration
and the longest duration is 45 years. The length of stay in leprosaria or colonies -41.3%
for 5-9 years, 27.7% less than 5 years and 9.6% over 15 years. And the longest stay in
leprosarium or colony is 41 years.
6. Previous occupation before admission-50.2% farming or fishery and 5.7% other jobs
and 44.1% unemployment. Their educational status is generally inferior to that of healthy
persons in Yeong Nam area, but the rate of their apprehension of Korean characters is
higher than general inhabitants. Their religions are 83.0% with protestants, 6.3% with
catholic and only 0.2% with buddhism or confucianism, and the rest 10.5% have no
religion.
7. As for their labour power, 58.0% of them have ability for heavy works and 28.7%
for light works, therefore 86.7% of them have labour power and the rest 13.3% have
lost labour power. Their living status shows 76.5% requiring relief and rhe rest 23.5%
able to keep livelihood, without any relief. Also 74.9% of the patients have contacted
with their families through correspondings or visits.
8. Their marital status shows that among those who got already married, majority of
their marriages were made between familiar patients, and it shows comparatively a high
rate of divorce or celibacy on account of the chronic disease. 13.5% of the whole
accommodated patients have the familiar patients in their families, and the indeterminate
group of the patients have rather more familiar patients in their families.
9. The results of their bacteriological examinations indicate a little higher positive rate
in the inmates of leprosaria than in those of leprosy colonies. And among negative
patients are many arrested cases.
10. The number of children or healthy persons, not yet disposed, living with the
patients, in leprosaria or colonies rates 5.7% in Kyong Buk Province and 18.6% in
Kyong Nam Province, and the number of newborn is increasing every year.
