It’s been 36 years since HIV/AIDS first made an appearance 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.
