Serological survey of leptospirosis among different groups in western Iran.

Leptospirosis is a zoonosis and a major public health problem. Blood sampling was done in the province of Kurdistan from 250 members of different groups, including hunters and their families, butchers and slaughterhouse workers, healthcare workers (HCWs) and those referred to medical diagnostic laboratories for routine testing. Sera were tested using an ELISA method to detect specific Leptsopira IgG antibodies. We found 20.80% (95% confidence interval, 16.23-26.25%) to be positive. The highest and lowest seroprevalence were in hunters (26%) and HCWs (18%). There was significant positive correlation between age and seropositivity ( P = 0.01). Hunting and eating the meat of the hare and exposure to dead or dying wild animals were found to be the main risk factors ( P < 0.05).
