[The epidemiological trend of brucellosis in the provinces of Sicily].

The epidemiological trend of brucellosis in Italy has been uneven over the last few years since there was a decrease in incidence in some regions and an increase in others, including Sicily. The peak was reached in 1997 when 59% of the cases were reported in Sicily alone. Appropriate intervention strategies are therefore needed both as regards the general population and exposed workers in order to reduce the spread of this disease.
