This study aimed to analyze the spatial distribution of COVID-19 cases in the municipality of Santa Izabel do Pará, identifying concentration patterns, considering the context of weaknesses in the Unified Health System (SUS) in the Amazon region. Data from the Notifiable Diseases Information System (SINAN), provided by the municipality's Epidemiological Surveillance, as well as cartographic bases available from the Brazilian Institute of Geography and Statistics (IBGE) were used for spatial analysis, with the QGIS software. The results showed a strong correlation between population density and the number of cases, with central neighborhoods presenting the highest incidence rates. These data highlight the need to implement transmission control measures in areas with higher population density, as well as to strengthen primary healthcare to ensure population access to health services. It is concluded that understanding the spatial distribution of cases, together with the analysis of socioeconomic and environmental factors, is fundamental for the implementation of more effective control strategies and to reduce the impact of COVID-19 on the population of Santa Izabel do Pará. However, it is important to note that this study has some limitations, such as the lack of more detailed data on population mobility and the quality of case notification data.
