In this context, hepatitis A presents with a serious public health problem. The objective of the research was the spatial and temporal analysis of hepatitis A, in the city of Belém / PA, using geoprocessing to verify the relationship with socioeconomic and environmental factors, from 2007 to 2016. Confirmed cases of hepatitis A were obtained from the System of Notification of Grievance. Firstly, a descriptive analysis of the sociodemographic profile was carried out using chi-square and frequency analyzes of the epidemiological profile of hepatitis A, originating Article 1. Spatial analyzes were demonstrated in article 2. The Global and Local Moran index were applied, the Kernel Density Estimator, the Kernel Ratio, and the spatial scan statistic. The analysis of article 1 indicated that hepatitis A affects more children, male, brown, with complete / incomplete elementary education, not vaccinated, without fixed institution, and laboratory tests are usually done for diagnosis and the main source of infection was contaminated water / food. The spatial analysis of article 2 showed that the administrative districts of Guamá, Belém and Sacramenta present a greater risk of transmission of hepatitis A. These districts are considered as precarious, informal and irregular places, lacking in infrastructure; and a high risk of transmission was observed in insular areas, which have poor or no sanitation conditions. Article 1 identified the highest risk groups and factors that most corroborate the infection of the individuals in the city of Belém. The analysis of the spatial epidemiology of hepatitis A (article 2) evidenced the need for investments in basic sanitation, for an effective reduction of disease.PPGCA - Estudos de ecossistemas amazônicos
