  • Objective : From an analysis of a community outbreak of measles in Youngju, Gyeongbuk, in March 2000, the authors evaluated the effectiveness of the measles vaccination and its determinants to Provide an epidemiologic basis for the establishment of a vaccination policy. Methods : Information was collected regarding the vaccinations from the health records of four primary schools and through a questionnaire surrey of the parents of students in two middle and two high schools (N=4638). Measles cases were surveyed from the patient list of each school and from case reports in the public health center. The attack rate and vaccine effectiveness of measles was evaluated by school; grade; frequency, region, and institution of vaccination. Results : The attack rate cf measles, 6.3% among the total subjects, was higher in middle school students (15.8%) than in primary (2.0%, p<0.05) and high school students (8.9%, p<0.05). The attack rate of the unvaccinated group was 4.6-fold higher than the vaccinated group in primary schools (p<0.05). Vaccine effectiveness was 83.2% among lower graders of primary schools, 34.0% among higher graders of primary schools,26.1% in middle schools, and -7.0% in high schools. In multiple logistic regression analysis, grade in school (odds ratio, 0.77; 95% CI=0.67-0.87) and frequency of vaccination (odds ratio, 0.57: 95% CI=0.37-0.58) were significant predictors of the outcome. Conclusions : We concluded that the explosive outbreak of measles in this area resulted from both inadequate vaccination coverage and secondary failure of vaccination. There was no evidence of any effect of the cold chain system on the vaccine failure.

  • Objectives : This study describes a plan that was designed to prevent a measles outbreak that showed a changed outbreak pattern. This study is based on the epidemiological investigation of a measles outbreak in a preschool in Incheon, Korea, 2006. Methods : The subjects were 152 students at a preschool where a measles outbreak occurred. A questionnaire survey was conducted and serological testing for measles-specific IgM was preformed. Results : Of the fifteen confirmed, identified cases, eleven patients had been vaccinated with one dose, one patient had received two doses and three patients were unvaccinated. The three unvaccinated cases consisted of one 5-year-old child, one 3-year-old child and one 16-month-old infant. For the cases with one dose of the vaccination, there were 11 cases, which consisted of six 5-year-old children, two 4-year-old children, two 3-year-old children and one 2-year-old child. The case with two doses of the vaccination was one 4-year-old child. The attack rate of measles was 100% in the 0-dose group, 11.2% in the 1-dose group and 2.0% in the 2-dose group. The vaccine's efficacy was 88.8% in the 1-dose group and 98.0% in the 2-dose group. The vaccine effectiveness for the 2-dose group was higher than that of the 1-dose group. Conclusions : High coverage with a 2-dose vaccination should be maintained, and the vaccination should be given at the suitable time to prevent a measles outbreak with a changed outbreak pattern.

  • Objectives : In this paper, the outline and overall content of the Majinhwiseong, a specialized medical text on measles written by Lee Wonpung was introduced, along with its academic historical meaning. Methods : The entire Majinhwiseong was analyzed according to content and form. In terms of form, organization, construction, cited literature, etc., were studied, while in terms of content, diagnosis of disease pattern and treatment formulas were studied. Later, based on cited medical texts and the author's social position, the academic historical meaning of this book was discussed. Results : Through the Majinhwiseong, Lee Wonpung strengthened the credibility of the text by not only providing medical knowledge on measles but listing their sources and comparing and analyzing related contents. In the diagnosis part, Lee focused on the changes in symptom, shape, color, and pulse of measles, discussing in detail its differential diagnostic methods. In the treatment part, while listing numerous formulas suggested by Ming (明) masters, Lee did not leave out treatment experiences of Joseon physicians. Meanwhile, the Majinhwiseong is indicative of measles medicine in 18th century Joseon having been progressed in the private sector rather than the official, and how the results of private sector medicine were being absorbed into the official realm through the Uiyakdongcham (議藥同參) system. Conclusions : The Majinhwiseong is a practical treatment manual written by clinician Lee Wonpung to deal measles which was widely spread at the time. The author organized existing medical knowledge on measles for clinicians while reflecting outcomes and medical situation of Joseon physicians in this book. Based on these findings, we could verify that medicine in 18th century Joseon had been progressing actively around the private medical sector.

  • Purpose : To determine the age-specific seropositivity and the level of measles specific IgG in vaccinated adolescents, the measles specific IgG titers were measured from the sera of junior & senior high school students in Seoul, Korea. Methods : From May to July in 1996, 216 sera were collected from junior & senior high school students(male : 110, female : 106) aged 12 to 17 years who were vaccinated and had no history of natural measles. Measles specific IgG titers were measured using ELISA method($SIA^{TM}$ Measles IgG Kit, Sigma Co. St. Louis, Mo). Results : The seropositivity of measles specific IgG in vaccinated adolescents aged 12 to 17 years was 91.2%. There were no significant correlations between age and seropositivity as well as between age and measles specific IgG level. Conclusions : We consider that our data suggest the necessity of revaccination of measles in adolescents. Further considerations should be required to establish an appropriate revaccination method and to evaluate the efficacy of revaccination of previously vaccinated adolescents.

  • Present study was undertaken to find when is right time for vaccination against Measles, Mumps and Rubella and what is the seropositive conversion rate after those vacinations. For this purpose, sera from 106 infants and children adimitted in Prediatric Department of Won Kwang University Hospital, Iri, Chonbuk, Korea were divided into 3 groups, such as (1) Vaccination group with definite information when it was given, (2) Unknown group whether vaccination was given or not, (3) Not vaccinated group. They were tested of IgG and IgM antibodies against Measles, Mumps and Rubella using Enzyme Immunoassay method and the following results were obtained. 1. Infants below 6 month of age showed to have IgG antibodies which seemed to have been transferred from mother in 87.8%(29/33) for Measles, 78.8%(26/33) for Mumps and 39.4%(13/13) for Rubella. And they showed IgM antibodies which are thought to have been produced by recent infection in 24.2%(8/33) for Measles, 48.5%(16/33) for Mumps and 9.1%(3/33) for Rubella. 2. Positivity of antibody IgG against Rubella was observed remarkably lower than it is against Measles and Mumps being only 39.4%(13/33) in $0{\sim}5$ month, 30.8%(8/26) in $6{\sim}11$ months, 30%(3/10) in $12{\sim}14$ months and 62.9%(22/35) in $18{\sim}36$ months of age. 3. ${\Delta}OD's$ of IgG and IgM antibodies against Measles were observed increasing with age being 0.444, 0.220 in $0{\sim}5$ months, 0.326, 0.134 in $6{\sim}11$ months, 0.581, 0.140 in $12{\sim}14$ months, 0.512, 0.000 in $15{\sim}17$ months and 0.887, 0.278 in $18{\sim}36$ months of age, respectively. 4. ${\Delta}OD's$ of IgG and IgM antibodies against Mumps were observed increasing with age being 0.427, 0.340 in $0{\sim}5$ months, 0.400, 0.249 in $6{\sim}11$ months, 0.694, 0.314 in $12{\sim}14$ months, 0.539, 0.165 in $15{\sim}17$ months and 0.854, 0.350 in $18{\sim}36$ months of age, respectively. 5. Vaccination for Measles, Mumps and Rubella is generally to start at 15 months of age in Korea, by which age their antibodies are found to exsist in more than 80% of tested samples. So, it seems to be very reasonable to start the vaccination schedule at earlier age than it does currently. 6. From the present study, it seems to have been clearly confirmed that Enzyme Immunoassay method is a reliable method with good reproducibility for mass survey of IgG and IgM antibodies against Measles, Mumps and Rubella in infants and children.

  • Objectives : The existence of specialized medical texts on a certain disease is reflective of its prevalence of the time. Smallpox and measles were major pediatric diseases, of which previous studies examined the outbreak of measles in late Joseon and the relationship among various specialized texts, and how records of the two diseases in the general medical literature has changed chronologically. Research on the two diseases recorded in different texts written by the same author has not been conducted before. Methods : Examination of the organization of the smallpox and measles parts in the Yosandangsinjipuibangkeumnangjibo and Bojeoksinbang, followed by comparative analysis was undertaken. Results : While the two texts show great similarity in the general contents of smallpox and measles, there was difference in the way they were written. In the case of the Yosandangsinjipuibangkeumnangjibo the author lists referenced literature, while in the Bojeoksinbang he does not. Also, compared to the Yosandangsinjipuibangkeumnangjibo, the Bojeoksinbang has detailed titles for the contents in both introduction and the detailed parts, while in the Bojeoksinbang there are contents that could not be found in the Yosandangsinjipuibangkeumnangjibo, along with more pattern differentiation in the former. Conclusions : The Yosandangsinjipuibangkeumnangjibo which was published in May of 1806 is a general type of medical text, in which the part on pediatrics is positioned in the first two volumes out of the entire 12 volumes, indicative of the author's emphasis on pediatric disease. The Bojeoksinbang which was published in December of 1806 discusses in-depth theories on smallpox and measles out of all pediatric disease, from which we can glimpse a specialized field of pediatrics in the late Joseon period.

  • Purpose : The aim of this study is to determine the age-specific seropositivity and the level of measles specific IgG in adults and to evaluate herd immunity to measles in Korea, the measles specific IgG were measured from the sera of adults over ages of 20 in Korea. Methods : 156 sera were collected from 156 out-patients over ages 20, who had visited clinical laboratory from June to July in 1997 at Korea University Ansan Hospital. The histories of natural measles or vaccination were not undertaken. Measles specific IgG titers were measured using ELISA method($SIA^{TM}$ Measles IgG Kit Co. St. Louis. Mo). Results : The results obtained from this study were as follows. 1) The seropositivity of measles specific IgG in adults was 94.9%. And there were no significant differences in their age and gender. 2) The mean measles-specific IgG titer was $238{\pm}84AU/mL$. And there were no significant differences in age and gender, except significant lower in 4th decades than other age groups. And there were no significant correlations between age and measles specific IgG level. Conclusion : In conclusion, a seropositivity of in adults was 94.9% which was higher than that of adolescents(91.2% in previous study), and antibody level was similar with adolescents. The herd immunity of the adults were considered to enough for protecting the transmission of measles in the community. For the eradication of measles in Korea, more efforts will be required to increase the vaccine coverage rate in children and adolescents.

  • Objectives : To increase the booster vaccination rate, the Korean government legislated a measles vaccination for elementary school students in 2001, requiring parents to submit a certificate of vaccination upon the admission of the students to elementary school. The purpose of this study was to evaluate the validity of measles vaccination certificates which were issued to parents. Methods : Using questionnaire survey data of 890 general practitioners and 9,235 parents in 2005, we investigated the evidence for booster vaccination certificates of measles. Results : In the survey of general practitioners, 59.5% of the certificates depended on the medical records of clinic, 13.5% was immunization booklets, 23.7% was reimmunizations, 1.9% was confirmation of record of other clinics, and 1.4% was parents statements or requests without evidence. In the survey of parents, 36.2% of the certificates depended on the medical records of clinic, 43.4% was immunization booklets, 18.0% was reimmunizations, and 2.4% was parents statements or requests without evidence. Conclusions : Our findings show that a majority of the booster vaccination certificates of measles was issued on the basis of documented vaccinations and it means that the implementation of the law requiring the submission of elementary school students' vaccination certificates has been very successful in Korea.
