Prospective serological study of leptospirosis in Southern Spain.
This article reports data concerning a serosurvey carried out in Southern Spain to assess the current epidemiological status of a population exposed to risk of leptospirosis.
Microagglutination and IgM-EIA tests were carried out on sera from a sample of workers in agriculture-related occupations, exposed to marsh waters.
A cohort of 197 workers were followed for a year in an active surveillance program to evaluate seroconversion (laboratory confirmed leptospirosis).
The results have shown for the cohort a density of incidence : 6.4 x 100 persons per year, and for the reference population an accumulated incidence of 41.25/100,000.
Prevalence rates (P) were 21.3 x 100 and 144 x 105 for the cohort and population respectively.
Rates were higher in cray-fishers (P : 62.7%), rice-workers, and butchers.
This is the first report identifying cray-fishers as a high risk group for leptospirosis, and the reporting of human contamination by Australis serogroup in Spain.
