AŞILI KAZAK ÖĞRENCİLERİN KALDIĞI YATILI OKULDA KIZAMIK SALGINI

Abstract

Background and Design.­ Measles outbreaks are being reported from vaccinated populations. This study was carried out in vaccinated Kazak students' dormitory in Istanbul.

Results.­ All of the 87 students in the school were male and the mean age was 18.2. (12­25) We diagnosed measles in 13 (15%) students. The mean age of the patients was 17.5. (12­22) The mean ages of the patients and the healthy ones were statistically similar. Eleven patients (85%) were positive for measles IgM. All healthy students except for two were positive for measles IgG.

Conclusion.­ These findings indicate that the measles outbreak in this mostly vaccination population has occurred among non­immune students and it is not due to decreased immunity after vaccination.
