국내에서 아직 잠복결핵 치료 대상 및 치료 방법에 대한 명확한 지침이 부족한 실정이며 이를 위해서는 잠복감염의 재활성화 혹은 새로운 감염이 어느 정도 결핵 발병의 원인이 되는지에 대한 연구가 선행되어야 한다. 그렇지만 발병의 위험이 높은 군을 선정하여 잠복결핵의 치료 대상으로 정하는 것이 타당할 것이며, 현재는 HIV 감염자, 전염성 결핵환자 가족 중 6세 미만의 아동, 중학생 및 고등학생에서의 집단 발병시 감염된 것으로 판정된 학생 및 종양괴사인자(tumor necrosis factor, TNF) 길항제 사용 예정인 잠복결핵 환자가 잠복결핵의 치료 대상으로 제한되어 있다. 향후에는 잠복결핵 치료 대상자의 확대가 필요할 것으로 생각되며, 치료방법 또한 isoniazid (INH) 단독 요법 이외에 rifampicin (RMP)을 포함하는 단기 요법의 사용도 고려하여야 하겠다. 현재 외국에서 잠복결핵의 치료법으로 권고되고 있는 것은 INH 6~9개월, RMP 4~6개월, INH/RMP 3개월 등이다. 과거부터 잠복결핵의 진단에 사용되어 온투베르쿨린 검사 외에 체외 인터페론감마 검사가 새로이 개발되면서 잠복결핵의 진단이 더 정확해진다면 이에 따라 잠복결핵 치료 방침도 수정될 가능성이 있으므로 새로운 검사법을 이용한 꾸준한 연구가 필요할 것이다.

호흡기계 및 소화기계에 감염된 전염성 바이러스에 대한 역학적 기초자료로 이용하고자 1999년 1월부터 12월까지 부산지역에서 분리된 전염성 바이러스의 특징과 계절적 발생추이, 환자의 성별, 연령별 발생에 대해 조사한 결과는 다음과 같다. 1. 1999년도 바이러스 가검물 2261건에서 분리한 호흡기계감염 바이러스 279건과 소화기계 감염 바이러스 83주를 분리하였으며, 이중 인플루엔자 바이러스 A형이 96주(29.6%), B형이 107주(33.0%)로 대부분을 차지하였다. 2. 1999년의 바이러스 분리의 성별 분포는 총 360명의 환자 중 179명(49.7%)의 남성 및 181명(50.3%)의 여성으로 비슷한 양상을 나타내었다. 이중 호흡기계의 경우 279명의 감염환자 중 남성이 130명(46.6%), 여성이 149명(53.4%)으로 여성의 감염율이 비교적 높았으나, 소화기계의 경우 83명의 감염환자 중 남성이 51명(61.4%), 여성이 32명(38.5%)으로 남성의 감염율이 거의 2배정도 높게 나타났다. 3. 1999년의 연령별 분포는 10세 이하의 어린이가 194명(59.9%)으로 대부분을 차지하였으며, 이중 인플루엔자 바이러스가 99명(30.6%)으로 가장 높은 감염을을 나타내었다 유행성이하선염 바이러스의 감염어린이 중에 $l1{\sim}15$세의 연령층이 15명으로(53.3%)로 가장 높게 나타났다. 4. 1999년 월별 감염율은 호흡기계 감염증 바이러스의 경우 1월부터 4월까지, 그리고 12월에 증가 추세를 보이면서 4월에 가장 높은 감염율을 나타내었다 소화기계 감염증 바이러스의 경우 9, 10, 11월을 제외한 모든 월별에 관찰되었으며, echo와 coxsackie 바이러스는 무균성 수막염 환자에서 하절기에 집중적으로 발생하였다. 동절기에 유행하는 설사 바이러스는 12월에 비교적 높은 양상을 나타내었다. 5. 인플루엔자 바이러스는 MDCK 세포에서, 아데노 바이러스와 유행성 이하선염 바이러스는 HEp-2 세포에서, 파라인플루엔자 바이러스는 Vero 세포에서, 그리고 echo, coxsackie B 바이러스와 장내 바이러스는 HEp-2, Vero, BGM 세포에서 뚜렷한 세포병변 효과를 나타내었다. 6. 분리한 바이러스는 전자현미경으로 관찰한 결과 인플루엔자 바이러스 A 형(HINI, H3N2)은 95nm, B 형은 70nm크기의 구형을 나타내었으며, 바이러스표면의 지질 이중층이 뚜렷하게 관찰되었다. 아데노 바이러스는 외피가 관찰되지 않았으며, nucleocapsid는 symmetry이고 크기는 71nm로서 바이러스 입자 표면에 icosaheral capsomer의 배열이 명확하게 관찰되었고, 파라인플루엔자 바이러스와 유행성 이하선염 바이러스는 외피가 있는 구형의 큰 viron으로180, 170nm 크기이었다. 7. Echo와 coxsackie B group 바이러스는 모두 외피가 없는 isometric 형으로 크기는 $30{\sim}45nm$ 이었고, enteric adeno 바이러스는 84nm 크기로서 외피가 없고, 입자 표면에 capsomer의 배열이 명확하게 관찰되었고, rotavirus는 크기가 70nm이며 외층 capsid 단백질과 내층 capsid 단백질이 두층으로 되어 있는 전형적인 수레바퀴 모양을 나타내었다. 이상의 결과로 보아 호흡기계 및 소화기계에 감염되는 전염성 바이러스는 연중 지속적으로 분리되고 있으며 전염성이 강하여 집단 발생은 일으키는 경우도 많고 최근 들어 유행성 이하선염과 흥역 바이러스의 발생률이 높은 추이를 나타내고 있지만 아직은 특이한 바이러스 치료제가 개발되어 있지 않았으므로 지속적인 대책과 아울러 장기적인 발생 가능에 대한 예방책을 흥보하여야 할 것으로 보이며 계속적인 바이러스성 전염병 유행예측조사 및 역학조사가 적극적으로 이루어져야 할 것으로 사료된다.

To exam infestation rate and removal rate of head louse, we did delousing at 27 primary schools and 19 kindergartens established as an annex to the primary school in Namwon-shi, Jollabuk-do, Korea, from May to December 1995. Total of 3123 subjects were examined ed for the presence of head lice and nits The overall infestation rate was 9.6%, 9.5% in primary school children and 10.1% in kindergarten children. Among 299 infested children, 55 children evaluated by live nit had louse, and 79 children had dead nit. According to distractive research, Ibaek-myon and Songdong-myon revealed high infestation rate of 27.3%, and 21.7% respectively. Infestation rate of primary school was 0 to 50.9%, kindergarten was 0 to 100%. Infestation rate of female children were higher than male in all grades. When we executed one time treatment with PARA$^{(R)}$ aerosol(bioallethrin with piperonyl butoxide), treatment rate of 65.1% was examined, 82.8% was examined in three times of treatment. We concluded that 3 times of treatments interval of 14 days were more effective than one time in the case of treatment of only infested children. In order to prevent the spread of head lice, education of school hygiene and suitable delousing attempts should be executed in the present situation.

Purpose : Shigellosis is still an important cause of acute food-borne diarrheal diseases throughout the world. We investigated the transmission routes and clinical course through the outbreak of shigellosis in Mapo-Gu, Seoul. Methods : From October 7th to November 19th in 2005, Mapo-Gu public health center had referred 32 patients with confirmed or suspected shigellosis to the National Medical Center. We had investigated source of infection, epidemiology, laboratory findings, and clinical course of the cases occurred during this outbreak. Results : Among 32 patients, 24 patients had been confirmed with shigellosis, 8 patients had been diagnosed with suspected shigellosis. They ranged in age from 5 months to 12 years old and their mean age was 6.5 years. The clinical manifestations were as follows; diarrhea, fever, abdominal pain and asymptomatic condition. Symptoms had sustained for 3.7 days on the average. S. sonnei were cultured by rectal swab and founded to be resistant to ampicillin and TMP/SMX except to 3rd generation cephalosporin. After treatment with antibiotics such as cefixime and ceftriaxone or imipenem and conservative treatment with electrolyte and fluid replacement for 5~7 days, Stool cultures of the rectal swab grew no Shigella in these cases except 3 cases. Conclusion : An outbreak of shigellosis had occurred in a preschool and elementary school children. From the same results of antimicrobial susceptibility and pulsed-field gel electrophoresis patterns in this study, we suggest that the outbreak of shigellosis in this report had been originated from a single strain. According to all negative results about suspected food and water cultures, we couldn't find out source of infection. Through materials offerred by Mapo-Gu Public Health Center, we presumed the trasmission routes probably were person-to-person.

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.

As the coronavirus disease(COVID-19) pandemic is declared and the number of confirmed cases and deaths increases in countries around the world, the world is gripped with fear. Therefore, in this study, psychological factors of infection prevention behaviors of firefighters and maritime police officers were analyzed based on the Health Belief Model. Although there was no significant difference in the COVID-19 prevention behaviors between the two groups, there was a significant positive correlation between the perceived disease infection possibility, perceived severity, and perceived benefits in the general characteristics and the COVID-19 prevention behaviors. There was no significant difference with perceived obstacles. This study is of great significance in that it is the first analysis of firefighters and maritime police officers as a health belief model, and can be used as basic data for the implementation of new infectious disease prevention actions.

This study was performed to observe the present status of intestinal parasitic infections in a remote island, Yondo, located in southern part of Jeonranam-do (Province) , Korea. In February and May, 1988, total 1,011 individual stool samples were collected and examined for intestinal helminths and protozoa using formalin-ether centrifugal sedimentation technique. The results are summarized as follows: 1. Of 1,011 inhabitants examined, 398(39.4%) were positive for intestinal parasites. Helminth positives were 372(36.8%) , and protozoan cyst positives were 56(5.5%) . 2. Ten species of parasites were found. Trichuris trichiura revealed the highest infection rate of 27.5%, Ascaris lumbricoides 17.4%, Taenia sp. 5.8%, Entamoeba coli 3.3%, Ciardia Zamblia 1.5%, Endelimax nasa 0.8%, Hymenolepis nana 0.4%, Hookworm 0.2%, Trichostrongylus orientalis 0,2%, and Entamoeba histolytica 0.2%, respectively. 3. The female group showed higher positive rate(44.0%) than males (34.7%). Also, higher positive rates were observed among adults as compared with the group younger than 10 years old. 4. Average value of E.P.G. was 1,876(range 200∼17,800) in A. lumbricoides positives, and 327 (range 200∼1,600) in T. trichiura positive cases. 5. In helminth egg Positive cases, single in(traction was 63.4%, double infection 34.7%, and triple infection 1.9%, respectively. Among protozoan cyst positives, single infection was 94.6%, and double infection was 5.4%. The present study revealed that the prevalence of intestinal parasites among inhabitants in Yondo island is still so high that special control measures should be performed.
