Enterobiasis is common helminthic infections found in man. But control of this disease is still troublesome because of its difficulty in the d diagnosis and prevention of infection. Considering the difficulty of accurate diagnosis of pinworm infection, which is very common and somewhat pathogenic, reevaluation of cellotape anal swab method for the diagnosis of enterobiasis was performed. A total of 147 children ranging the ages of 1-12 years in 3 orphanages in the suburbs of Seoul, Korea was subjected for this study. Repeated cellotape anal swabs were carried out against 70 children, 7 times for 3 days interval, in the morning 6am. Finally 10 mg/kg body weight pyrantel pamoates were given to all children including egg negative cases and whole stools of 3 following successive days were collected for the confirmation of residual worm ourden at the time of treatment. Cellotape anal swabs were also performed to another 77 children at 6am, 3pm, 9pm, twice for 3 days interval. The resultant findings were summarized as follows; 1) While the each time average detection rate of Enterobius egg was 28.8% in this study group, the accumulative detection rate up to 7th examination was 62.8%. The accumulative detection rate rose continuously up to 6th examination. 2) After administration of pyrantel pamoate 10 mg/kg body weight, final infection rate was increased to 72.9% by adding worm positive cases who didn't show any evidence of infection in the cellotape anal swabs. 3) Although pinworms were detected in 35 among 70 children treated, 7 cases (20%) of them were egg negative cases in 7 consecutive cellotape anal swabs. 4) Pinworms were expelleded in 14 (87.5%) among 16 children whose swab result was positive in the last examination which was done concurrently with drug administration. 5) Estimated infection rate calculated by best asymptotically normal estimate of Neuman from Moriya's modification revealed 71.5% similar to 72.9% of present results. 6) The result of anal swab performed at 6am was higher than that of 3pm or 8pm. In conclusion, cellotape anal swab method for Enterobius vermicularis infection was considered as method having relatively high positive accuracy. However to gain the reliable infection rate, at least 6 examination is required in the group with 25-30% infection rate by single swab. Moriya's modification of Neuman could be used efficiently in the mass control of this diease for the estimation of true infection rate of E. vermicularis in the sampled population.

The prevalence rate of Enterobius vermicularis eggs was investigated among preschool children located in the area of Iksan, Jeonbuk, during the period from March to July, 2005. Of the 1,082 children examined 78(7.2%) were found to be positive for E. vermicularis egg by the adhesive cellotape anal swab method. The egg positive rate of male and female were 6.7% and 7.8%, respectively. The positive rates range from 5.1% to 8.7% among preschool children, and the highest egg positive rate was observed in the 7 year old age group. Through this survey, it was determined that the E. vermicularis infection is still prevalent among children in Jeonbuk, Korea.

Stool and cellotape anal swab examinations were carried out in August 1997 on handicapped people at an institution located in Chorwon-gun, Kangwon-do, Korea. A total of 112 stool samples (78 males and 34 females) revealed three cases of Trichuris trichiura infection and one case of Enterobius vermicularis infection. Other helminth eggs were not detected. The overall prevalence rate was 35.7% (38.5% for males and 29.4% for females). More than two different kinds of parasites were found in 42.0% of the positive stool samples (17 cases). The infection rates for protozoan cysts are as follow : Entamoeba coli (25.0%), E. histoIUtica (1.8%), Endolinax nana (21.4%), Iodoamoeba butschlii (1.8%) and Giardia lamblia (0.9%). In cellotape anal swab examinations (165 samples), the prevalence rate of E. vemicularis was 20.6% (25.7% of males and 9.6% of females). In conclusion, the handicapped people in the institution showed higher infection rates of protozoan parasites and E. vemicularis, possibly due to more accessibility to the infection.

To investigate the infection status of Enterobius vermicularis the author tried surveys by srotchtape anal swab on school-children and household environmental factors considered to have inauences on the infection were analysed by an inquiry method with questionnaire. The survey was carried out in October, 1986 and 1988 in urban and suburban areas and the results could be summarized as follows: 1. The egg Positive rate in anal swab. was 16.0% (male 14.5%, female 17.6%) out of 2, 156 school-children and higher in female group. 2. The egg Positive rate of suburban school-children (175% out of 1, 305 children of two primary schools) was a little higher than that of urban school.children (13.6% out of 851 children of one primary school). 3. The questionnaire analysis on environmental factors showed some significant relations between the egg Positive rate and such factors as the number of brothers and sisters, householder's occupation, and availability of childroom or bathroom. The results indicate that, although enterobiasis in school-children has shown decreasing tendency in Korea, it is still considerably high in some urban and suburban areas.

An unusual over-gravid female of Enterobiw uemiculcris was recovered from a 15-month old child by cello-tape anal swab. The patient resided in Inchon and complained of severe anal itching. The worm measured 7.8 mm in length and 0.5 mm in width, and retained typical morphologic features of E. uemiculnris such as cephalic alas and a sharply pointed posterior end. In this gravid female, peculiarly. the uterus was tremendously distended, and about 99% of the whole body length was completely packed with a great number of eggs. Other internal organs were difficult to observe. This paper describes a peculiar over-gravid female of E. vemiculcyis.

To determine the status of Enterobius vermicularis infection among children living on western and southern coastal islands of the Republic of Korea, children (3-10 years) in 39 kindergartens and primary schools were examined using the cello-tape anal swab method, during July and August 2000. Of 1,661 children examined, $307(18.5\%) $were found to be positive for E. vermicularis eggs. The highest infection rate $(59.3\%)$ was found in a kindergarten and a branch school of Shinyang primary school on Chujado, Jeju-do (Province), Remarkable differences in egg positive rates were observed in different localities. The egg positive rate for boys $(21.3\%)$ was significantly higher than that of girls $(15.4\%)$ (P=0.02). However, positive rates were not significantly dependent on age. The results of the present study show that E. vermicularis infection is highly prevalent among pre-school and primary school children living on the western and southern coastal islands of the Republic of Korea, and indicate the need for efforts to control this infection.

To know the prevalence of Enterobius vermicularis infection and what are the most important risk factors, we evaluated the incidence and risk factors of enterobiasis among children attended in kindergartens in Busan metropolitan city, Republic of Korea. A total of 1,674 children from 21 kindergartens in 11 of 16 autonomous districts of Busan were evaluated for E. vermicularis infection by the cellotape anal swab technique. The overall egg-positive rate for E. vermicularis was 10.7% (179/1,674), and the prevalence of enterobiasis in each kindergarten ranged between 0% and 32.4%. There was an increasing tendency of the egg positive rate according to the population density; the higher the population density communities had, the higher egg-positive rate for E. vermicularis was detected (P = 0.001). Among personal hygiene factors involving children, thumb-sucking (P = 0.036) and fingernail-trimming (P = 0.024) were highly associated with enterobiasis. In addition, taking anthelmintic medications against E. vermicularis infection was strongly associated with enterobiasis (P = 0.014). Moreover, parents' knowledge of enterobiasis was correlated significantly with the incidence of enterobiasis of their children (P = 0.006). In conclusion, we need to consider not only personal hygiene but also parents' knowledge about enterobiasis as a factor in order to develop new strategies for elimination or to complete reduction of enterobiasis in Korea.

Purpose : Enterobiasis is probably one of the most common parasitic infection world-wide. Human is the only known host of Enterobius vermicularis. Children are more commonly infected with Enterobius vermicularis than adults and infections are commonly recurred. In Korea, there is a high prevalence. So, we performed this study to evaluate the present status of Enterobius vermicularis infection among children in the Masan, Changwon areas and to determine the efficacy of flubendazole against this parasitic nematode. Methods : From November to December, 1997, urban and rural elementary school children and urban preschool children were examined for the presence of Enterobius vermicularis egg. All the children were examined once by an adhesive cellotape anal swab technique in the early morning at home by their parents guided by specific instructions for the technique. Results : 1) A total of 644 adhesive cellotape anal swab specimens was collected from 205 urban elementary school children, 290 rural elementary school children and 145 urban preschool children. Among them, 114(17.7%) were positive for Enterobius vermicularis eggs. There was no significant differences in the rate with regard to sex. 2) In the preschool children, the egg detection rate was 42(29.0%) out of 145 children. This rate was significantly higher compared with 72(14.4%) of 499 school children. 3) The egg detection rates in the rural and urban school children were 15.2, 13.7% respectively. There was no significant difference in both groups. In the 3rd grade and below in elementary school children, there was a higher rate compared with above 4th grade group. 4) In day care center where egg detection rate was high as 41%, the children were given two doses of 100mg flubendazole every 3 weeks, including staffs and family members. After treatment, egg detection rate fatted as 6%. Conclusion : Our data demonstrated that there was high prevalence of Enterobius vermicularis infection. In the light of these results, it is necessary to examine and treat children as soon as possible.

This study was undertaken to evaluate the present status of parasitic infection and swine pen human latrine system in Cheju Do, from July to September 1982. The 663 stool specimens (male 323 and female 340) and 579 scotch tape anal swabs collected from 161 households of 2 areas in Cheju Do were examined. The methods employed were formalin-ether technique for the prevalence rate of various helminthic and protozoan infection, and scotch tape anal swab technique for the prevalence rates of Enterobius vermicularis. In addition to these, questionaire was used to evaluate the present status of swine pen human latrine system and prevalence rates of taeniasis in these areas. The results are as follows ; 1) Prevalence rates of parasitic infections of any kind was 33.9%. It was 35.7% in Cheju City in contrast to 32.1% in North Cheju Gun. The infection rates of Trichuris trichiura was 10.0% and it was the highest prevalence rate in this survey. The prevalence rates of the other parasites were as follows ; Ascaris lumbricoides 2,3%, Hookworm 0.2%, Clonorchis sinensis 0.5%, Hymenolepis nana 1.5%, Entamoeba coli 3.2%, and Giardia lamblia 0.5%. 2) The infection rates of Enterobius vermicularis in 579 peoples (male 285, female 294) by applying scotch tape anal swab technique was 13.1% through the survey. It was 16.9 in Cheju City and 8.5% in North Cheju Gun. 3) The Infection rate of Taenia species by applying the stool examination and making up a question was 19.2%(21.4% in Cheju City and 16.7% in North Cheju Gun). 4) Sexual distribution of the parasitic infections showed slightly higher rate in female than that of male. 5) The positive rates of parasitic infection by the stool examination and questionaire positive cases of taeniasis were higher in 0-9 and over 60 year old than any other age group. 7) The swine pen human latrine systems were used in 46 households (28.6%). 7) Relationship between swine pen human latrine system and taeniasis was not noted.
