Abstract
PURPOSE
In May 2008, a diarrhea outbreak occurred among students of in a girls' high school (S school) in Sangju-si, Korea. An epidemiological investigation was carried out to clarify the cause and transmission route of the outbreak.
METHODS S school has been providing meals directly since July 2007. We conducted a questionnaire survey among 591 persons, and examined 283 rectal swabs and 98 environmental specimens. The patient case was defined as a member of S school who had diarrhea more than one time in a day, accompanied with one or more symptoms among abdominal pain or tenesmus from May 19th to May 26th 2008.
RESULTS The attack rate was 24.0%. Bacillus cereus were cultured from three of the rectal swabs and five of the preserved foods. It was suspicious that contamination was possible in seasoning vegetables, and we found some foods were seasoned with spices after being cooled by moving cooler for about 20 minutes. Enterotoxin positive B. cereus were cultured from two foods cooled by moving cooler.
Enterotoxin negative B. cereus were cultured from two environmental specimens of the moving cooler.
CONCLUSIONS We presumed the cause of the diarrhea outbreak in S school was food poisoning by B. cereus. Because enterotoxin positive B. cereus were cultured from rectal swabs and foods, and the symptoms were corresponded. We estimated the outbreak was occurred by this process that B.
cereus in the moving cooler contaminated foods during cooling and then rapidly proliferated.

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.
