I recently got interested in Spatial Epidemiology. I had never done studies that used health related datasets, neither had I used R; so we a week for myself, I thought it would be interesting to create a small project using R.
I had recently read about Neglected Tropical Diseases (NTD, which are not rare, but mostly affect neglected regions of the world. There is only a limited spatial analysis (compared to Zika or ebola), even though the impacts of NTDs in some countries are tremendous.
I downloaded some datasets for 8 NTDs from the WHO website, and some prevalence data from ntdmaps.org and tried to find trends in the dataset. It was mostly exploratory, I have published a long description of the project on my Github blog: http://helenedraux.github.io.
