Notes:

• Until 2017, the method used to estimate HIV incidence used a Serologic Testing Algorithm for Recent HIV Seroconversion (STARHS) method to estimate incidence. Starting with 2017 estimates, the CDC released a new incidence estimate method based on a CD4 depletion model (CD4 methodology). The 2017 change and the 2019 updates result in estimates that are on average 32% and 10% higher respectively, than the STARHS method used at the time ETE was planned.
