Methods This was a sectional study without treatment of diagnosed cases of tuberculosis and deaths, having TB as underlying or associated cause on people older than 15 years, from 2005 to 2014, residents in Ceará. Results There was an increase of 2,325 (6%) cases after the merger of SINAN TB, TB deaths (underlying or associated cause) SIM and cases of TB/HIV in SINAN AIDS, as well as improving information about the closure criteria and registration of HIV infection. The increase was higher in small municipalities.
