- OBJECTIVES
Toxoplasmosis is a member of the zoonosis group and may cause congenital infection. Antibody positive rates of toxoplasmosis were examined in high school students in Cheju, Korea to facilitate the study aim of examining the seroprevalence of Toxoplasma gondii in school teachers of child-bearing age in Cheju Island. METHODS: The study population comprised teachers of child-bearing age in primary, middle and high schools, aged 35 years and younger, who wished to be tested for Toxoplasma gondii antibodies (IgG) by the indirect latex agglutination test (ILA) and the enzyme-linked immunosorbent assay (ELISA) method. RESULTS: The overall antibody positive rate was 3.8% in the study subjects (n=314), a rate which showed no significant difference due to birth place, history of bringing up pets, or history of contacting a cat. CONCLUSION: We confirmed that the seroprevalence of Toxoplasma gondii in a population of child-bearing teachers in Cheju Island was the same as that previously reported in other parts of Korea.

- BACKGROUND
Congenital rubella syndrome (CRS) can be controlled by vaccination. Because rubella is typically a childhood disease, occurring predominantly in the 5 to 14 year age group, female school teachers may be a high-risk population for CRS. CONCLUSIONS: To determine the prevalence rate of rubella antibodies in school teachers of child bearing age. METHODS: The study population consisted of primary, middle and high school teachers of child bearing age. The subjects were aged 35 years and younger, and consented to immunoglobulin (Ig) level testing using the ELISA method. RESULTS: The positive rate of IgG was 77.9% in the study subjects (n=314). Sixty-three teachers (21.4%) were susceptible to rubella infection. Thirty-seven teachers (11.8%) had a history of rubella vaccination. Among the female teachers with no vaccination history, the proportion of negative IgM and IgG was 21.7%, and the proportion of positive IgM was 2.9%. Seventy-nine percent of the study subjects did not know that they should not become pregnant for three months after receiving the rubella vaccine. CONCLUSION: School teachers of child bearing age should be considered a high risk group for CRS, and should be vaccinated if they are found to be seronegative.

- OBJECTIVES
To assess the seroprevalence and risk factors of toxoplasmosis in high school students in Cheju Province, Korea. METHODS: A total of 4,570 high school students from 18 schools in Cheju Province were investigated for Toxoplasma gondii antibodies(IgG) by enzyme linked immunosorbent assay (ELISA). Risk factors for toxoplasmosis, such as place of residence, type of house, contact with cats and other pets, and rare meat consumption, were examined by questionnaire. RESULTS: The overall antibody positive rate was 5.5% and ranged from 2.6 to 11.5% by school. There was no significant difference between males and females. Statistical analyses of the questionnaire data indicated that the risk factors for seropositivity were: (1) birth place (Cheju/others), (2) place of residence (rural/urban), (3) dietary habits (vegetarian/non vegetarian), (4) eating rare meat, (5) exposure to pets and (6) hepatitis B. CONCLUSION: We confirmed that the prevalence of the anti-Toxoplasma gondii antibody in a population of high school students in Cheju Province was to the previously reported prevalence.
