Camacho & Reinhard stated in the December 2019 issue of the KJP (57: 621-625) that we confused a pollen grain with an Enterobius egg found in the grave of a female adolescent residing in ancient Tehran 7,000 years ago". We want here to clarify and answer to the outlined points in their article.

This survey was performed to investigate and compare egg positive rates (EPRs) of Enterobius vermicularis among preschool children in 3 Korean localities (Chuncheon-si, Inje-gun, and Paju-si) in 2008. A total of 7,048 preschool children were examined. Overall, the total EPR was 4.0%; the EPR was the highest in Chuncheon-si (5.6%), followed by Inje-gun (4.5%) and Paju-si (3.4%). The EPR of boys (4.9%) was higher than that of girls (3.1%). The EPR significantly increased with age, with the highest observed in 5~7-year-olds. These findings demonstrate that E. vermicularis infection is widely prevalent among preschool children in Chuncheon-si, Inje-gun, and Paju-si, Republic of Korea.

While the presence of pinworm eggs in archaeological samples has been reported by many researchers in the New World, those have been detected very scarcely in the Old World, especially in East Asian countries. In fact, many parasite species were recovered from the archeological remains in Korea, eggs of Enterobius vermicularis had not been found. Recently, a female mummy buried in the 17th century was discovered in the Joseon tomb from Dangjin-gun, Chungcheongnam-do, Korea. After rehydration process for 12 days, investigations were carried on the luminal surface of the colon. From them, 3 eggs of E. vermicularis were recovered. They were elliptical, transparent with a thin egg shell, $50.3{\pm}5.2\;{\mu}m$ (length) and $28.2{\pm}3.9\;{\mu}m$ (width) in size. This is the first discovery of E. vermicularis eggs in East Asia.

An epidemiological study was undertaken to estimate the prevalence of Enterobius vermicularis infection among the primary (and infant) school schildren in Ysngyang-gun, Kyongsangbuk-do. During the period from 2 to 14 December 1983, a total of 2,227 school children in 13 schools were examined one time by means of scotch-tape anal swab technique with a simple questionaire study on perianal itching, enuresis and school record. The results are as follows: 1. The overall egg Positive rate was 64.1% and the rate ranged from 46.6 to 86.7% by schools. 2. The egg positive rates of boys and twirls were 60.5 and 68.0% respectively and the difference was statistically significant (P<0.005). 3. There was noted a tendency of decrease in prevalence by increase of the age of children. 4. It was revealed that perianal itching and school record were significantly correlated with E. vermicularis infection (P<0.05) while not in case of enuresis (P>0.1).

A survey of the infection rate of Enterobius vermicularis among students in 4 primary schools located in Gangwon-do (Province) was done from May to .Tune 2001. Among the 398 examinees,39 (9.8%) were infected with E. vermicularis demonstrated by the adhesive cellotape anal swab method. The infection rates ranged from 8.3% to 11.8% among the four schools. The infection rate of males and females was 10.7% and 7.7% respectively. The first grade students showed the highest infection rate, 28.7%. The confirmed cases were treated with albendazole three times at an interval of 15 days. We were able to confirm that E. vermicularis infection is still prevalent among students in Gangwon-do , Korea.

Objectives: This study was conducted to investigate the occurrence and possible risk factors of enterobiasis among children in kindergartens. Methods: A total of 3,921 children were examined from 36 kindergartens in Ulsan, Korea. The parents were asked to complete questionnaires and to detect Enterobius vermicularis infection using the anal swab technique. Results: The overall rate of being positive for E. vermicularis egg was 7.8% ranged from 0 to 29.0%. The infection rate was related to age, gender, thumb sucking, pre-medication of anthelmintics, employment status of mother and number of siblings. The risk factors significantly associated with E. vermicularis infection were gender(OR 1.628), thumb sucking(OR 1.643), pre-medication of anthelmintics(OR 0.614), employment status of mother(OR 0.574) and number of siblings(OR 0.388). Conclusion: We propose that E. vermicularis infection screening among children in kindergartens should be continued on a regular basis. In addition, more intensive control program should be developed and applied to children.

우리나라의 아동에서 요충감염의 양성을 알아보기 위하여 서울지역의 국민학교 학동 936명과 전북 옥구군에 위치한 농촌지역의 국민학교 학동 308명 그리고 서울 난지도에 거주하고 있는 92명의 아동에 대하여 Graham 씨법으로 검사하였다. 서울지역의 국민학교 학동에서는 936명중 114명에 요충란이 검출되어 12.2%의 양성율을 나타내었고, 농촌지역의 국민학교 학동에서는 308명 중 77명이 충란 양성자로 25.0%의 양성율을 나타내었다. 난지도에 거주하고 있는 92명의 아동에서는 요충란 양성자가 26명으로 28.3%의 양성율을 나타내었다. 서울지역 국민학교 학동의 충란양성율은 농촌지역 국민학교 학동의 양성율보다 낮았으며 같은 서울지역에서는 난지도 아동에서 충란양성율이 높았다. 남자 아동의 충란양성율은 여자 아동에서의 충란양성율보다 낮았으며, 국민학교 학동의 경우 고학년이 될수록 양성율이 저하되는 경향을 보였다.

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.

We assessed the prevalence of Enterobius vermicularis infection and changes in the egg positive rate (EPR) over 1-year time, using the adhesive cellophane-tape perianal swab method in 2,347 preschool children in Muan-gun, Jeollanam-do, Republic of Korea in 2008 and 2009. The overall EPR for E. vermicularis was 4.1% in 2008 and 4.5% in 2009. A study population of 389 children was repeatedly examined for 2 years. Within this group, the EPR in 2009 was twice higher than in 2008, and the EPR of the group of 5-7-year-old children was significantly higher than that of other age groups. Moreover, in the group of 5-7-year-old children in 2009, the rates of positive and negative conversion were significantly higher and lower, respectively, than in other age groups. Conclusively, enterobiasis was prevalent during 2008-2009 among preschool children in Muan-gun, Jeollanam-do, and the increased EPR in 2009 was due to an increase in newly acquired infections among 5-7-year-old children.

The present study was performed to determine the prevalence of Enterobius vermicularis among preschool children in Gimhae-si, Korea. A total of 6,921 preschool children in 76 kindergartens were examined using the cellotape perianal swab method. The overall egg positive rate (EPR) was 10.5%. The EPR in boys was higher than that in girls (adjusted odds ratio (AOR): 1.5, P<0.001), and it was higher in rural than in urban children (AOR: 1.2, P=0.022). The present study confirmed that the prevalence of E. vermicularis infection is fairly high among preschool children in Gimhae-si. Therefore, systematic control and preventive measures should be adopted to reduce morbidity associated with this nematode infection.
