Objective: To describe the epidemiology of cases of human rabies in Ceará State, Brazil, 1970-2019. Methods: We analyzed secondary data from the State Department of Health and the reference hospital. Results: Of 171 cases, 75.7% occurred in males, 60.0% in <19 year-olds, and 56.0% in urban areas. Rabies was transmitted by dogs in 74.0%, marmosets in 16.7% and bats in 7.3%. Between 1970 and 1978, there was an increase of cases (by Joinpoint Regression Program, annual percentage change [APC] = 13.7 – 95%CI 4.6;41.5), and 1978-2019 a decrease (APC = -6.7 – 95%CI -8.8;-5.9). There was a reduction of transmission by dogs (71 cases, last case in 2010) and an increase by sylvatic animals (5 cases since 2005). Conclusion: This study demonstrates changes of transmission dynamics of rabies during the last years, with reduction of transmission by dogs and relative increase of transmission by sylvatic animals.
