The CDC has created a map that shows the Rates of Adults and Adolescents living with a diagnosed HIV infection by the area of residence. This map was created in 2015 with data taken from 2013. Though there are many areas where there is no data seen, The areas with the highest rates are located in the Southeastern USA.
In a study by the CDC for the year of 2016, the rates of sexually-transmitted infections (STI) per state was studied. The map seen above shows the comparison of the rates of each state. The state with the highest STI rate in 2016 was Alaska; in comparison, the state with the lowest STI rate was Vermont. It is very interesting to see where the states are that have the higher rates (lower numbers on the scale) and most of them are states in the South East.
