Changes in Racial Disparities in Viral Suppression Among People with HIV from 2013–2020
Characteristics of US Counties with Low Pre-exposure Prophylaxis (PrEP) Use and Limited Access to PrEP Prescribing Clinics
Pre-exposure prophylaxis (PrEP) is central to Ending the HIV Epidemic, yet uptake in the United States remains low and geographically uneven. Counties with persistently low PrEP use and limited local PrEP-prescribing infrastructure may represent “PrEP deserts,” where geographic and structural barriers to HIV prevention converge. Prior studies have relied on travel-time measures or census tract-level analyses, limiting county-level insight. We con…
Prior-Year Substance Use Disorders and Subsequent HIV Retention in Care Among Men Living with HIV Who Have Sex with Men
