Data Sources: NYS HIV Surveillance System and NYC DOHMH HIV Surveillance System.
Incidence and undiagnosed estimates are calculated using a CDC methodology released in 2022.
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).
