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
PURPOSE
This study was conducted to improve the Korean influenza management system and to determine the status of influenza vaccination in some community health centers through a survey of the officers in charge of influenza vaccination.
METHODS
The authors conducted a questionnaire survey by e-mail for the officers in charge of influenza vaccination of 8 community health centers in Daegu-si, 5 community health centers in Ulsan-si and 25 community health centers in Gyeongsangbuk-do. The authors developed a questionnaire including selection methods of the influenza vaccination objects, results of influenza vaccination in 2002, problems of influenza vaccination, the population within the respondents`jurisdiction and so on.
RESULTS
The proportion of influenza vaccination at community health centers among all residents in the 2002-2003 influenza season was 3.8% in Daegu-si, 14.8% in Ulsan-si, 15.1% in urban Gyeongsangbuk-do and 24.9% in rural Gyeongsangbuk-do. The proportion of influenza vaccination at community health centers among priority cases for vaccination was 12.9% in Daegu-si, 43.1% in Ulsan-si, 39.3% in urban Gyeongsangbuk and 41.6% in rural Gyeongsangbuk-do. The officers in charge of influenza vaccination stated that the problems of influenza vaccination were deficiencies in preparatory examination such as manpower shortage. Twenty-five persons stated as a problem that influenza vaccinations conducted in the hospitals were hardly reported, and fifteen of these clarified that this was due to hospital indifference.
CONCLUSIONS
The authors examined all community health centers of Daegu-si, Ulsan-si, and Gyeongsangbuk-do, and investigated the vaccination states and problems that health officers were dealing with. Therefore, this study is meaningful with its basic data for the management of domestic influenza vaccination.

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
S: In May 29, 1999, the health department in Gumi city received a report from a local pediatrician that three children who attended a kindergarten were diagnosed with amebic dysentery. By May 31, fifteen more children from the same kindergarten were diagnosed with amebic dysentery. We conducted an investigation in order to verify the diagnosis, and to implement appropriate control measures.
METHODS
We conducted a questionnaire survey on 264 children in 3 kindergarten in Gumi city. Furthermore, 726 children in 4 kindergarten and 13 academies in Chilgok county whose lunch is supplied by the same unlicensed catering company were monitored for diarrheal symptoms.
RESULTS
Of 264 children in Gumi city, 74 children fitted the case definition (attack rate, 28%). Of 726 children in Chilgok county, 50 children were reported to have diarrheal symptoms. The clinical picture was dominated by the following symptoms; abdominal pain (85.1%), fever (83.8%), headache (50.0%), chilling (45.9%), vomiting (28.4%). The median duration of diarrhea was 2 days, and the median frequency of diarrhea was 3 times/day. Salmonella Typhimurium of the same antibiogram pattern were isolated from fifteen cases. However, no evidence of amebiasis was found from laboratory results or epidemiologic pattern.
CONCLUSIONS
: This epidemic was caused by Salmonella Typhimurium, which were present in lunch supplied by the unlicensed catering company. Improvement of the diagnostic ability in local health centers as well as public health centers and reinforcement of strict protocols regarding appropriate management of catering services should be emphasized

Abstract
PURPOSE
A field investigation was done to evaluate the level of the epidemic of Shigellosis in Jeju Island during the first half of year 2000.
METHODS
Confirming the Shigellosis was done by the structured questionnaire and the result of rectal swab for the residents having a diarrhea.
RESULTS
As the confirmed patients with Shigella sonnei were 933 from 25 April to 14 August 2000, the crude incidence rate was 174 per 100,000 persons. The highest incidence rate was shown in 5-9 year-old group. Especially the south area of Jeju Island, called as Namjejugun, had the major epidemic occurrence.
CONCLUSIONS
The huge and chronic epidemic of Shigellosis was confirmed. The nature of this epidemic suggested that the endemic occurrence had been existed in Jeju Island.

Abstract
OBJECTIVES
This study was performed to evaluate the occupational relationship on 190 cases of cancer selected out of 622 cases of cancer registered in two university hospitals from January 1, 1996 to December 31, 1997.
METHODS
The selection criteria was for the patient to be more than 40 years old with lung, liver, urinary bladder, nasal cavity and skin cancer or leukemia. We reviewed the medical records to update the missing data and occupational histories. Telephone interviews were used to obtain complete occupational histories on the subjects.
RESULTS
The sites of cancer in the order of relative frequency was lung (51.0%), followed by liver (32.9%), urinary bladder (14.1%) and skin (2.0%) in male, liver (41.5%), followed by lung (31.7%), skin (19.5%) and urinary bladder (7.3%) in female. The occupational histories of 190 cases with suspected cancer-causing occupations were recorded 5.8% on the doctor's medical records and 33.2% on the nursing records. The response rates of the telephone interviews were 87.4%. The distribution of occupation according to the telephone interviews was farmer (47.7%), office worker (16.1%), salesman (12.8%), production worker (6.7%), simple laborer (3.4%) and unknown (13.4%) in male, housewife (63.4%), farmer (17.1%), saleswoman (9.8%) and unknown (9.8%) in female. And there were two cases of suspected occupational relationships in the lung cancer cases.
CONCLUSIONS
We could not discover definite cases of occupational cancer but found out two cases of suspected occupational relationships. Occupational cancer is likely to increase in the near future, so the efforts to detect occupational relationships with cancer should be continued.
