Abstract
This report is a part of study results on Leptospirosis Control Campaign in Army. Total number of persons subjected in this study was 1, 889 which were studied in two seasons, 860 in autumn (October-November 1987) and 1029 in early summer (May-June 1988).
The studies were mainly divided in two parts which includes epidemiological analysis and char acterization of the subjected population by interview survey and microbiological analysis including serologic studies on the same subjects to provide base line data for the Leptospirosis control which is an important health problem not only in military but also in general population in this country.
The results are summarized as follows;
1) In bacterial isolation studies only 2 isolates were confirmed to be Leptospire and these two isolates demonstrated strong reaction with anti-L. icterohaemorrhagiae lai serum.
2) The percent of antibody positives serum to Leptospire confirmed by microagglutination tests(MAT) were 10.1% in autumn (1987) and 9.3% in early summer (1988). The difference in two study periods was not significant.
3) The seroconversion rate after the exposure to the field (military trainings) was 8.4%, which were tested a month after the exposure. No significant changes in seroconversion rates observed in 3 consecutive years since 1986(7.6%) were recognized.
4) The differences in antibody positive rates by their ranks, duration in military, their specialties and present military activities were not significant. Especially, those who served in military for a long time were found to have almost the same antibody positive rate compare to those served for shorter period of time.
