abstract = "Fasciola hepatica is the causative agent of fasciolosis, a disease
that triggers a chronic inflammatory process in the liver
affecting mainly ruminants and other animals including humans. In
Brazil, F. hepatica occurs in larger numbers in the most Southern
state of Rio Grande do Sul. The objective of this study was to
estimate areas at risk using an eight-year (2002-2010) time series
of climatic and environmental variables that best relate to the
disease using a linear regression method to municipalities in the
state of Rio Grande do Sul. The positivity index of the disease,
which is the rate of infected animal per slaughtered animal, was
divided into three risk classes: low, medium and high. The
accuracy of the known sample classification on the confusion
matrix for the low, medium and high rates produced by the
estimated model presented values between 39 and 88% depending of
the year. The regression analysis showed the importance of the
time-based data for the construction of the model, considering the
two variables of the previous year of the event (positivity index
and maximum temperature). The generated data is important for
epidemiological and parasite control studies mainly because F.
hepatica is an infection that can last from months to years.",
