[Knowledge of high school students about HIV and AIDS].

In 475 students attending the last school year in four high schools in the town of Povazská Bystrica, Slovakia a questionnaire survey of students' knowledge of HIV infection and AIDS was carried out. 76.33% of all answers to questions in the questionnaire were correct. We found no significant differences between the percentage of correct answers among schools, among boys and girls and among students living in the country and in town. 56% of the students fought that there is enough information about HIV infection, AIDS and about prevention of that infection. Nevertheless the percentage of correct answers to some questions in the questionnaire do not correspond to this statement.
