You might want to try some kind of linear regression for your index, where index is a measure of Cholera risk. 

I´m planning to develop an index who that gives me the opportunity to analize analyze those the preexisting factors or drives that increase the social vulnerability to diseases. 

The metodology would be make use of official databases about of basic information related to health coverage, age, insurance, and education.
