Standardized information systems and availability of reliable information are essential for monitoring the quality and coverage of health services. The Sistema de Informação de Agravos de Notificação (Information System for Notifiable Diseases SINAN) is the system of data collection, processing and dissemination of data generated routinely about the injuries around the country. The injuries accidents with venomous animals, anti rabic attendances, dengue, schistosomiasis, leprosy, viral hepatitis, tuberculosis and chickenpox stand out in the SINAN in Ouro Preto, MG. In This research was proposed in order to investigate their occurrence in the period 1999-2008, aiming to support new intervention strategies to prevent such problems and increase the resolvability of curative actions. General Objective: to analyze the distribution of major diseases of compulsory notification by SINAN the period 1999 to 2008, in Ouro Preto, MG, to support new intervention strategies at the municipal level. Specific Objectives: to describe and analyze the historical prevalence of distribution of accidents with venomous animals, anti rabic attendances, dengue, schistosomiasis, leprosy, viral hepatitis, tuberculosis and chickenpox in 1999-2008, in Ouro Preto, MG, according the variables age, sex, area of residence and year of notification; and analyze the quality of data collected included in the SINAN, as instruments of planning processes and decision making. Methodology: This is an epidemiological study using survey data from SINAN, through their reporting and research forms. TABWIN, software developed by Datasus, and Microsoft Excel 2003 were used for tabulation and data analysis. The reporting period covers the years 1999 to 2008. Conclusions: In Ouro Preto, MG, during the studied period, there are remarkable differences in patterns of prevalence of the injuries accidents with venomous animals, dengue and tuberculosis, as compared to the literature consulted. The other injuries did not demonstrate this difference. The validity of SINAN depends on the quality of data, which, in turn, is linked to the proportion of research and reporting forms properly filled and by the care in their processing. It can be seen a clear increase in the ability to capture the SINAN data over the period studied, but losses are still great records. Moreover, most of medicals professionals are not cognized of the importance of their role in epidemiological surveillance of notifiable diseases. From the analysis of data in the SINAN, new intervention strategies at the municipal level are proposed: the use of geo-referencing of health events, given its importance in the analysis and assessment of risks to public health, and the inclusion of chickenpox vaccine in the municipal basic vaccination calendar, because even there are not complications in most case, the social and economic cost is high. Nevertheless, increased investments for the Epidemiological Monitoring municipal are keys to improving the quality of data entered into the information system.
