A significant portion of diarrheal diseases is directly related to the lack of environmental sanitation. Although governments, through health promotion, have been working to mitigate this problem, the continuous supply of good quality water for human consumption and the search for sanitary improvements is still a challenge given the socioeconomic conditions of many regions. Knowledge about the water quality conditions that supply smaller cities and large urban centers and the diseases that are related to this determinant must be monitored in order to promote the search for solutions in the short and long term. In this sense, the present study aimed to verify the bacteriological relationship of water in the Muzambinho river, associated with an index of diarrheal diseases and climatic factors. In this way, the sampling plan of the quantitative data of this research was carried out, covering water collection from the Muzambinho River, from September 2016 to August 2017, corresponding to the climatic seasons of the year, taking into consideration and seasonality and climatic conditions. Data were also collected on the incidence of diarrhea in the period evaluated, as well as temperature and rainfall values ​​for the region studied. Analyzes of the presence of E. coli, total coliforms, heterotrophic bacteria were carried out, as well as assessment of dissolved oxygen levels in the waters of the Muzambinho River. The results demonstrate that the period evaluated the association between the climatic and bacteriological variables has a weak to moderate relationship with the prevalence of diarrhea, with values ​​of r = 0.42 for temperature and r = 0.2 for rain, while for levels of heterotrophic bacteria. OD. E. coli and total coliforms, the values ​​found were r = 0.04, r = 0.14, r = 0.006. respectively. However, when employing the specific analysis for diarrhea, there was a strong influence of temperature and rainfall in the number of reported cases. As a conclusion, this work showed that the water quality of the Muzambinho river is outside the established standards and that the climatic variables are determining factors in the diarrhea index in the region during the studied period. These results make it possible to design new conservation strategies from the river and to combat the emergence of new cases of diarrhea in the population of the studied environment.
