About this data
The US counterpart to the Europe map: CDC surveillance (via AIDSVu) records how each new HIV diagnosis (ages 13+) was acquired. Each value is the number of new diagnoses a state reported that year for the selected route: male-to-male sexual contact (gay & other men who have sex with men, defined by sex assigned at birth — bisexual men are counted here too), heterosexual contact, injection drug use, MSM & injection drug use, and Other (which folds in perinatal at ages 13+). These are counts, not rates — CDC publishes no rate for the transmission breakdown because population denominators by route don’t exist — so more populous states show bigger numbers. Counts are statistically adjusted for missing transmission information; small suppressed cells are grey; 2020 reflects COVID-19 disruption and the latest year is preliminary. Each route has its own colour scale; pick one and drag the year slider or press play.
