According to the Centers for Disease Control and Prevention (CDC), from 2013-2017, the estimated rate of HIV infection diagnosis in all 50 US states and District of Columbia decreased. The annual number of diagnoses remained stable. In 2018, the rate was 11.4 per 100,000 population, [76] and 37,832 individuals were diagnosed with HIV infection that year. Numbers and rates of HIV infection increased in some subgroups and decreased in others. Variations in trends among groups are expected and may result from differences in testing behaviors, targeted HIV testing initiatives, and/or changes in the numbers of new HIV infections in some subgroups. [77]

From 2013-2017, the annual number and rate of HIV infections classified as stage 3 (AIDS) in the United States decreased. In 2018, the rate of infections classified as stage 3 (AIDS) was 5.2 per 100,000 population. The number and rate of deaths among persons with infection ever classified as stage 3 (AIDS) remained stable. In 2017, the rate of deaths in persons with stage 3 (AIDS) was 3.9 per 100,000 population. Deaths among persons with stage 3 (AIDS) may be due to any cause. [76]
