The head louse infestation had been no problem since 1960s in Korea. However, the present study revealed high infestation rate among the primary school children in Seosan-gun, Chungnam Province in July 1983. The cases of louse positive were determined by identifying the adult worms and/or their llits on scalp and hairs. The overall louse positive rate among 615 children examined was 73.5%. The rate was higher in girls (78.8%) than in boys (67.6%) and was highest in 3rd-4th school grades. It was observed that the more the number of family members the higher the infestation rate of children. The positive children were treated with 20% benzyl benzoate solution after the teat for louscidal effect in petri dish. However, establishment of intensive control measure is needed to prevent further infestation.

In order to know the prevalence of head louse among the school children in rural area, we visited 3 primary schools and a kindergarten in Sanbuk-myon, Mungyong-gun, Kyongsangbuk-do in July 1985, and examined the children to identify the adult worms of head louse and/or its nits on the hair. The overall infestation rate was 91.9% among 420 children examined, and there was a difference between schools (P<0.05). The school girls' rate, 96.1% was higher than that of boys' 88.9%(P<0.05). By grade, the rate of infant school was 88.5% and 1st to 6th grade were 100, 100, 95.8, 90.4, 89.7, 80.0% respectively. Above result indicates that the head louse is an important health problem in this community. Therefore, the chemotherapy and the effort to improve the hygiene are necessary in this community by physicians, teachers and health administrators.

국내 4개 국민학교를 선정하여 머릿니 기생률을 조사한 결과 총 2,515명의 바동 중 972면이 양성으로 평균 38.6%의 기생률을 보였다. 이들 양성자에게 0.4% 훼노스린 분제 ($Sumithrin^{\circledR}$ powder)를 집단 처리하여 머릿니 구제효과를 조사하였다. 1회 처리시의 구제율은 93.4%이었고, 약 10일 간격으로 2회 처리시의 구제율은 94.8% 이었다. 1회와 2회 처리시의 구제율에 있어 유의성을 찾아볼 수 없기 때문에, 집단처리 할 때는 1회 살포로 구제가 가능하다고 생각된다. 린노스린 분제 처리 7개일 후의 머릿니 기생률이 5.4%로서 처리 전의 33.1%에 띠해 83.4%의 감소율을 보였다.

Head louse infestation is a significant public health problem across the world, particularly among preschool and primary schoolchildren. This study investigated the trends of head louse infestation in the Republic of Korea over a 9-year period (2011-2019), targeting primary schoolchildren in 3 areas of Seoul, 4 other large cities, and 9 provinces. A survey was administered annually by the health staff of each regional office (n= 16) of the Korea Association of Health Promotion (KAHP). The branch offices of KAHP examined a total of 51,508 primary schoolchildren, comprising 26,532 boys and 24,976 girls. Over the 9-year survey, a total of 1,107 (2.1%) schoolchildren tested positive for adults and/or nits of Pediculus humanus capitis. The prevalence was 2.8% (133/4,727) in 2011-2012 and gradually decreased to 0.8% (49/6,461) in 2019 (P< 0.05). Head lice were found more frequently in girls (3.0%; 746/24,976) than in boys (1.4%; 361/26,532) (P< 0.05). In terms of geographic localities, the highest infestation rate, 4.7% (average prevalence over 9 years), was observed in southern Seoul (Gangnam branch of KAHP), whereas the lowest infestation rate, 0.7%, was seen in Gyeongsang (north and south provinces) and western Seoul. Although the prevalence decreased significantly during the 9-year period, head louse infestation remains a health and hygiene issue among primary schoolchildren in the Republic of Korea. Regular surveys along with health education are needed to further improve children's hair hygiene.

The purpose of this study is to know the present situation of head louse infestation among the students in Ysngyang-gun, Kyongsangbuk-to. From May 11 to June 20, 1984, a total of 5,937 students in 23 primary and 3 middle schools were examined to identify the adult worms of head louse andlor their nits on the hair. The results are as follows: 1, The overall infestation rate was 44.5% and the rates ranged from 19.6% to 88.6%A by each school. 2. In primary schools, the rate was 53.0%A and in middle schools, 27. 1%. 3. The school boys'rate was 33.2% and the school girls'55.6%, and the difference was statistically significant (P<0.001) . 4. The rates were different by grades in middle schools. 5. The rates were different by areas (Myons) (p<0.001) . 6. The adult worms collected from the students were Pediculus humanus roar. capitis.

우리 나라 대도시와 농촌 지역 어린이의 머릿니 감염 실대를 알아보기 위하여 1988년 5일 부터 1989년 10월까지 서을 시내 8개 지역, 장승포시 및 농촌 지역 8군데 등 총 17개 지역 내에 소 재한 28개소의 유치원, 국민학교 및 중학교에 재학중인 어린이에 대하여 머릿니 감염 여부를 조사 하였다. 총 피검자 11,865명 중 2,900명이 감염되어 평균 감염률은 24.4%이었으며, 도시 지역보다 농촌 지역 아동의 머릿니 감염률이 월등히 높았다. 유치원 연령을 제외한 모든 연령에서 남자보다 여자의 감염률이 높았으며, 머릿니의 감염률이 가장 높은 연령은 9∼12세(국민학교 3∼6학년)이었다. 앞으로 머릿니 구제를 위한 보건 교육 및 집단 관리 대책이 조속히 마련되어야 할 것으로 판단 된다.

The infestation status of head louse among children attending primary schools and kindergartens in Chinju-shi, Kyongsangnam-do, Korea, was investigated between June and July 1999. Out of 2,288 children examined, 3.9% of boys (48/1,242) and 23.5% of girls (246/1,046) were infested with nits or adult/nymphs of lice. The effectiveness of lindane shampoo (1% gamma benzene hexachloride solution) was evaluated after one or two time applications to all the children infested. The negative conversion rate of pediculosis was 93.5%. Effective control measures are needed to control and prevent such ectoparasite infestation amongst children.

Growing patterns of pediculocidal drug resistance towards head louse laid the foundation for research in exploring novel anti-lice agents from medicinal plants. In the present study, various extracts of Pongamia pinnata leaves were tested against the head louse Pediculus humanus capitis. A filter paper diffusion method was conducted for determining the potential pediculocidal and ovicidal activity of chloroform, petroleum ether, methanol, and water extracts of P. pinnata leaves. The findings revealed that petroleum ether extracts possess excellent anti-lice activity with values ranging between 50.3% and 100% where as chloroform and methanol extracts showed moderate pediculocidal effects. The chloroform and methanol extracts were also successful in inhibiting nymph emergence and the petroleum ether extract was the most effective with a complete inhibition of emergence. Water extract was devoid of both pediculocidal and ovicidal activities. All the results were well comparable with benzoyl benzoate (25% w/v). These results showed the prospect of using P. pinnata leave extracts against P. humanus capitis in difficult situations of emergence of resistance to synthetic anti-lice agents.
