It’s been 36 years since HIV/AIDS first popped up in the US.

The disease quickly spiraled into an epidemic, but medical advances have since made HIV controllable with medication – especially if diagnosed early.

An estimated 1.1 million Americans currently live with HIV in the US, however, and thousands still die from AIDS every year.

AIDSVu, a project run by Emory University’s Rollins School of Public Health in partnership with biotech company Gilead Sciences, has been mapping HIV by county since 2010.

On Wednesday, it released its newest data – the maps show the prevalence of HIV as of 2014, as well as new diagnoses from 2008 to 2015. Here’s what the researchers found.


AIDSVu gets its data from state and city health departments that collect information on a local level. This map looks at the number of new HIV diagnoses, with darker purple denoting more diagnoses in a given county.

By mapping HIV rates on a local level, public health officials can get insight into which groups might need more attention (based on geography or demographics). Here’s the breakdown of Seattle by zip code — the first time AIDSVu has collected this detailed of information about the city.

Dr. Patrick Sullivan, the project’s lead researcher, told Business Insider that southern states are disproportionately affected by HIV. In this map, the darkest red shows areas with more than 381 diagnoses per 100,000 people.

In fact, the five cities with the highest rates of new diagnoses are all in the south: Miami, Jackson, New Orleans, Baton Rouge, and Atlanta. Here’s Atlanta’s breakdown by zip code — the darkest purple represents areas where there were more than 114 new diagnoses per 100,000 people in 2015.

Sullivan also said that one age group is experiencing a disproportionate amount of new diagnoses: Those between the ages of 13 and 24. Here’s what the number of cases of HIV looks like across the country for 13 to 24 year olds (though in some counties the data was not released).

This group accounted for more than 25% of all new diagnoses, a 2% increase from the year before. New diagnoses overall, however, have decreased by 18% over a 7-year period.


In addition to providing a breakdown of HIV prevalence in the US, the project also maps out where testing centers are, as well as where people can get access to preventive treatments. The CDC recommends people between 13 and 64 get tested at least once.
