A bar chart showing the estimated number of HIV transmissions in the U.S. from 2017 to 2021. In 2017 there were 36,500, plus or minus about a thousand. In 2021 there were 32,100, plus or minus about two thousand.
Notes: Estimates from 2020 and 2021 should be interpreted with caution due to the impact of Covid-19 disruptions on HIV testing. Given overlapping estimate ranges (the shaded portions), 2018, 2019, and 2020 estimates may not be different from 2017 levels.
