A retrospective epidemiological study about epidemiology of rabies in Chile between years 1989 and 2005 was done. A data base of 39793 national registries of rabies samples was analyzed by means of statistical packages. Out of 39793 analyzed cases, 719 bats, 7 dogs, 7 cats, I bovine and I human were positive to rabies throughout the 17 years of this study. The statistical analysis established a significant increase in the proportions of positivity in bats, with predominance of variant 4 between the reservoirs. Given the complexity of the wild cycle of the rabies in Chile, it is necessary to maintain a program control of rabies, directed to educate people for a responsible possession of domestic animals, due to the risk of rabies transmission from bat to the susceptible species.
