Objectives: Leptospirosis is a worldwide zoonotic infection with a much greater in tropical and temperate regions and has now been identified as one of the emerging infectious diseases. Because of leptospirosis is significantly high in temperate regions, rice field workers and livestock animals; it will be necessary to evaluate condition of leptospirosis in Mazandaran province, Iran.

Methods: In this survey, 127 serum samples of suspected human were collected in different parts of Mazandaran province from November 2006 to July 2007. Serums were tested by Indirect Immunoflurescence Assay (IFA) in Pasteur Institute of Iran, Amol Research Center, Department Of Parasitology.

Results: The results showed that prevalence of Leptospirosis disease in Mazandaran province is 25.98% using IFA methods. In this survey, 33 samples were positive which 84.85% of them were belonged to male and 15.15% to female. Rice field workers showed the most frequent occurrence of infection and showed significant variance with other occupations (P < 0.01). Among 107 samples that were collected from males and 20 from females, 26.16% and 25% samples were positive, respectively. There was no significant variance between genus and leptospirosis (P > 0.05). Living place (urban or rural) and contact with animals did show no significant variance with leptospirosis. The most positive cases were found in age range of 40–50 years.

Conclusion: Because in Mazandaran Province, men and women work together at rice field, also urban peoples still relate to agriculture, it is acceptable that genus and living place have not significant variance with prevalence of leptospirosis. In order to as certain that the effect of contact with animals has no significant variance with the prevalence of leptospirosis, it needs more investigations, direct sampling from animals or their urine and comparison of them to the results of this study. The IFA test is a potentially valuable tool for the diagnosis of leptospirosis.
