HIV remains a persistent problem for the United States. While great progress has been made in preventing and treating HIV, there is still much to do. This section provides a broad overview of the effects of HIV in the United States and its territories.

Are some regions of the United States more impacted by HIV than others?

Yes. HIV is largely an urban disease, with most cases occurring in metropolitan areas with 500,000 or more people. The South has the highest number of people living with HIV, but if population size is taken into account, the Northeast has the highest rate of people living with HIV. (Rates are the number of cases of disease per 100,000 people. Rates allow number comparisons between groups of different sizes.)
