ABSTRACT. Baptista D.Q., Bruhn F.R.P., da Rocha C.M.B.M., Torres F.C., Machado E.D., Sáfadi T. & Pereira S.M. Temporal series analyses in equine infectious anemia cases in the State of Rio de Janeiro, Brazil, 2007 to 2011.

E-mail: daniqb@yahoo.com Equine Infectious Anemia (EIA) is a disease caused by a cosmopolitan infection of which the etiological agent is the Lentivirus, which reaches equines in general. This paper presents the results of a survey of the EIA in the State of Rio de Janeiro, Brazil, by means of a temporal series from 2007 to 2011. In addition, was estimating a model of case occurrences in subsequent years. The occurrence of EIA in the State is low (0.43%), with the highest occurrence being in 2007 (0.63%). The Livestock Defense Regionals (LDRs) that had the highest prevalence of this disease were Rio de Janeiro, Niterói, Cordeiro and Tres Rios, however, the LDRs, such as Barra Mansa, Itaocara and Campos dos Goytacazes had the lowest number of tests performed, thus presenting the lowest prevalence values. This disease is still considered endemic in the state of Rio de Janeiro. The prevision analysis indicates an approximate prediction (p<0.01) of the real observation of the number of EIA cases in the State of Rio de Janeiro in the year of 2011, thus constituting an important tool for planning the control and eradication of EIA.
