Abstract
International migrants could be considered a risk group susceptible to vaccine-preventable diseases. We conducted a measles seroprevalence study among 419 marriage migrant women living in Sinan-gun and Wando-gun, South Jeolla Province, located in the southwestern part of Korea. The overall seroimmunity was 92.8%. The seroimmunity varied considerably according to the country of origin and increased with age. Our current analysis could be valuable in the context of discussions concerning vaccination policies for immigrants in Korea.

전라남도 신안군과 완도군에 거주하는 결혼이주여성 419명을 대상으로 홍역항체 양성률을 조사하였다. 전체적 항체양성률은 92.8% 로 높았으나, 나이로 나누어 분석하였을 때, 30세 미만에서는 83.1% 로 30세 이상의 95.5% 에 비해 통계적으로 유의미하게 낮았다. 출신국가에 따른 분석에서는 캄보디아 출신의 경우 30세 미만에서 항체 양성률이 40.0 % 에 불과하여, 타국가 들에 비해 통계적으로 유의미하게 낮았다.
Key Message
To prevent measles resurgence, continuous monitoring of immunity in communities, including foreign-born populations who may have different serostatus, is essential.

Abstract
OBJECTIVES
Although the nationwide inoculation rate of varicella vaccine was approximately 95% in Korean children recently, the number of notified varicella cases is unexpectedly continuously increasing till now. To suggest some hypotheses regarding this discrepancy, an age-period-cohort (APC) analysis as a descriptive epidemiology study was conducted for children residing in Jeju-do, Korea.
METHODS
The raw data were obtained from the nationwide database for insurance claim of healthcare fee provided by the National Health Insurance Service, Korea. The selection criteria were children aged 2-13 years who visited any healthcare center due to varicella from 2005 to 2016 while residing in Jeju-do. After calculating the birth cohort-specific crude incidence rates by age and year, the intrinsic estimator method was used to perform the APC analysis.
RESULTS
As the annual crude incidence rates decreased with increasing age between 2005 and 2016, the age and period effects also decreased. The intrinsic estimator coefficients suggesting the cohort effect shifted from positive to negative in 2011, the starting year of free varicella vaccine program in Jeju-do.
CONCLUSIONS
The results suggested that inoculated varicella vaccines have preventive effects. However, further studies to evaluate waning immunity would be needed.
Summary
Korean summary
2011년 이후 생후 12-15개월 유아에게 수두백신 무상접종을 시행해 오고 있는 제주도에 있어서, 수두발생 신고건수가 증가하는 괴리 현상에 있어, 국민건강보험공단의 수진자료를 확보하여 연령-기간-코호트 (age-period-cohort, APC) 분석을 시행하였다. 그 결과 연령이 증가하고 연도가 최근으로 올수록 수두 발생에 대한 연령과 기간효과는 점점 감소하는 반면, 수두백신 무상접종이 시작된 2011년을 전후해서 코호트 효과는 양에서 음으로 전환하였다. 따라서 현재 접종하고 있는 수두 백신은 수두발생을 예방하는 효과가 있으며, 돌발수두 발생은 이차백신 실패로 볼 수 있다.

Abstract
<p>The authors report a fatal case of disseminated tuberculosis in a 14-yr-old girl, which developed immediately after a measles-rubella (MR) vaccination. Despite a markedly accelerated clinical course which led to death within two weeks, the authors could not identify any possible cause of the tuberculosis aggravation in this case, with the exception of the MR vaccination. The possible role that MR vaccination had on the clinical course of tuberculosis in this case is discussed.</p>

Abstract
PURPOSE
To maintain measles elimination status, we evaluated the seropositivity of measles and mumps according to time interval since the first or second dose of MMR in children aged 4 to 6 years, who are starting communal life. MATERIALS AND METHOD: 2,447 children aged 4 to 6 years were enrolled at 251 public health centers over the period of March to May 2007. Subjects were verified their date of MMR vaccination and then their blood was sampled for serologic test. Measles and mumps IgG antibody was tested by ELISA at Korea CDC.
RESULTS
Vaccination coverage was 99.9% in the first dose, 64.9% in the second dose regardless of gender. Seropositivity of measles and mumps was 95.7%, 85.5% in the first dose and 98.7%, 98.1% in the second dose, respectively. The seropositivity of measles was 88.1% in 6-year-olds who did not receive the second dose of MMR. As time since receipt, seropositivity of measles tended to decrease over time and was 93.3% in vaccinees over 48 months after the first dose.
CONCLUSION
A first dose MMR at 12-15 months cannot lead to herd immunity. More public information is needed to encourage second dose vaccination before admission to day-care center or kindergarten.

Abstract
OBJECTIVES
To estimate the complication rate and the societal cost of measles, a survey was conducted in Seoul, Jeonju city, and Kyonggi province in 2001.
METHODS
A telephone survey was conducted in Jeonju city (175/307) and four local areas of Kyonggi province (793/1,238) to gather information on the complications of measles. To estimate societal cost, the telephone survey was conducted for the sampled subject by complication type and the age group. The response rate was 78% (180/230). Paid bills were examined for direct cost estimation, and the time cost and the transportation expense were analyzed for indirect cost estimation.
RESULTS
The incidence of a complication of measles was 3.1% which found to be higher in younger age group. The incidence of pneumonia, otitis media, and encephalitis were 2.1%, 0.8%, and 0.2% respectively. Direct and indirect costs of in-patients without a complication were $417.00 (US $1.00 = 1,000 won) and $256.00 per case, respectively, and the out-patients who have no complication were $54.00 and $65.00, respectively. The average cost for a patient with measles without complication was $119.00 as the result. The societal cost of encephalitis was high as $6,660. Estimated total societal cost of measles ranges from $14 million to $69 million in the year 2000.
CONCLUSION
Complication rate of measles was fairly low compared to foreign countries. The lower rate could result from the difference in vaccination rate and the age distribution of the measles patients. The cost of measles without complication was not high. However, the cost for the complication and the total disease burden caused by measles shown to be high in the year 2000.

Abstract
BACKGROUND
The outbreak of measles from 2000 to 2001 was the biggest epidemic since measles vaccination was introduced in Korea. Outbreak of measles in Yeongju was one of the earliest milestones of the nationwide outbreak in the year 2000. The authors investigated epidemiologic characteristics of the outbreak in this area.
METHODS
The authors estimated attack rate through the investigation of all the school age cases of measles reported to local health authority between March and May, 2000. Case investigation was done to trace the source of the outbreak. One hundred seventy two cases were examined with medical examination, with interview on their clinical manifestations, and with serologic examination on the anti-measles IgM and IgG antibody.
RESULTS
Overall attack rate among the school children was 4.3%, with highest attack rate in middle school students (8.5%). The outbreak began in March in middle schools, which spread to elementary and high schools. IgG was positive in 160(93.0%) cases and IgM was positive in 94(54.6%) cases, among which 90 cases (95.7%) were also positive for IgG. IgM positive cases had higher prevalence of rash (91.5%) compared to those without IgM (70.5%). Diagnostic criteria based on the clinical manifestation and contact history showed the highest sensitivity (92.6%) compared to conventional diagnostic criteria in outbreak (40.4-44.7%) CONCLUSIONS: High proportion of susceptible children in the population due to primary or secondary vaccine failure played a key role in this outbreak. Clinical manifestation was milder than classical measles and adjustment of diagnostic criteria can be helpful in the management of outbreak.

Abstract
PURPOSE
There has been an epidemic of measles in Korea since 2000. Therefore, we analyze the epidemiologic haracteristics of measles in Gwangju Metropolitan City.
METHODS
We reviewed the epidemiologic investigation records and laboratory data of the measles patients reported in Gwangju Metropolitan City from January 1st 2000.
RESULTS
1) Demographic characteristics: Totally, 3,392 cases were surveyed and 3,300 cases were enrolled (3,300/3,392, 97.3%). Fifty-four percents of the patients were male (1,771/3,300) and forty-six percents of the patients were female (1,529/3,300). Average age of the patients was 8.20 years (8.20 5.56 years). Forty-seven percents of the patients were reported in the interval from November 2000 to December 2000 (1,582/3,298, 47.9%). 2) Clinical manifestations of the patients: Common symptoms of measles patients were fever (3,300/3,300, 100.0%), skin rash (3,068/3,300, 93.0%), cough (2,889/3,300, 87.5%), rhinorrhea (1,883/3,300, 57.1%), headache (1,445/3,300, 43.8%), conjunctival injection (1,182/3,300, 35.8%), and oral thrush (832/3,300, 25.2%). Among the patients, 250 patients had complications (250/3,300, 7.6%) and most of them were respiratory complications (220/250, 88.0%). 3) Vaccination: Eighty-six percent of the enrolled patients answered the question about vaccination (2,854/3,300, 86.4%); 808 patients were not taken a shot (808/2854, 28.3%), 1,762 patients received one dose (1,762/2,854, 61.7%), and 284 patients received additional dose (284/2,854, 9.9%). 4) Laboratory data: Laboratory confirmed cases were 780 patients (780/3,300, 23.6%); 603 cases were confirmed serologically, 185 cases were positive in PCR, and virus was isolated in 6 cases. Genetic sequencing of the isolated viruses was clade H1 and closely related to that of China.
CONCLUSION
Therefore, adequate surveillance and maintenance of high coverage rate of the vaccination would be the crucial factors to eradicate measles

Abstract
PURPOSE
S: This study was to investigate the source of infection, mode of transmission and incidence of a measles outbreak among infants living in a Gwangju welfare institution in July 2000.
METHODS
The information about 63 children was collected through the nurses interview and blood sampling and laryngopharyngeal swab were conducted to the children. In addition, an epidemiologic survey was performed to confirm the infection dissemination route.
RESULTS
Before the outbreak, two children living at the institution were admitted to a university hospital for other health problems. These children shared a room with a 5 year old diagnosed with meningitis who was later diagnosed as having measles after rashes appeared. The two children developed measles after returning to their institution and the infection spread to other children in the institution. Among 63 children observed, 14 children(22.2%) developed measles, secondary attack rate of measles due to index cases was 19.7%. And 78.6% of the patients were between 4 and 8 months old. The room where the index case lived showed an attack rate of 81.8%, which is a much higher rate compared to other rooms. The attack rate among boys(26.0%) was higher than that of girls(12.5%), but it was not statistically significant.
CONCLUSIONS
This outbreak was considered to be a nosocomial infection, where the index cases were admitted to a hospital, infected and the infection spread to children. Further studies are necessary to find out the maternal antibody levels of infants of post-vaccinated mothers and the optimal age for measles vaccination.
