The DHIS is an important system used for health monitoring, improving disease surveillance,pinpointing outbreaks and speeding up health data access.It was implemented in Kenya in the year 2010.In this project the data is obtained from the DHIS, specifically for Migori county.The main aim is to analyze the patient’s data, visualize it and infer a number of things like the causes of various diseases in the county, the trend over the years, what does the trend signify and health policies can be made to improve the health system. We shall use R graphics for visualization and R libraries for our analysis. This will help draw evidence-based conclusions and inferences that go a long way in supporting the recommendations that we shall put forth.
