Abstract Background The global COVID-19 pandemic has the potential to indirectly impact transmission dynamics and prevention of HIV other sexually transmitted infections (STI). It is unknown what combined reductions in sexual activity interruptions HIV/STI services will have on epidemic trajectories. Methods We adapted a model HIV, gonorrhea, chlamydia for population approximately 103 000 men who sex with (MSM) Atlanta area. Model scenarios varied timing, overlap, relative extent...

<sec> <title>BACKGROUND</title> Despite advancements in HIV prevention, many Americans, particularly those from historically underserved communities (e.g., racially and sexually minoritized individuals people who use drugs), continue to face significant barriers accessing crucial prevention services such as testing pre-exposure prophylaxis (PrEP). Integrating these into community pharmacies is a viable yet underutilized solution overcoming access-related challenges. However, few studies have...

Abstract Background The US Centers for Disease Control and Prevention (CDC) recommends comprehensive sexually transmitted infection (STI) screening every 3–6 months men who have sex with (MSM) using human immunodeficiency virus (HIV) pre-exposure prophylaxis (PrEP). gaps between these recommendations clinical practice by region not been quantified. Methods We used survey data collected from the internet-based ARTnet study 2017 2019 on STI among MSM across United States, stratified current,...

Daily preexposure prophylaxis (PrEP) use can prevent up to 99% of HIV infections; however, PrEP uptake is low due poor access PrEP-prescribing locations for populations at increased risk HIV, especially in the southeastern US. Pharmacies are a feasible option increase access, but little known about how they could complement current locations.To examine geographic distributions compared with pharmacies and facility need ratios (PFNRs) according Southeast describe potential reach expand...

ABSTRACT Background The global COVID-19 pandemic has the potential to indirectly impact transmission dynamics and prevention of HIV other sexually transmitted infections (STI). Studies have already documented reductions in sexual activity (“sexual distancing”) interruptions HIV/STI services, but it is unknown what combined these two forces will on longer-term epidemic trajectories. Methods We adapted a network-based model co-circulating HIV, gonorrhea, chlamydia for population men who sex...

UNAIDS estimates global HIV investment needs in low- and middle-income countries (LMICs) at $26 billion per year 2020. Yet international financing for programs has stagnated amidst despite the increasing number of people requiring accessing treatment. Despite increased efficiencies service delivery, evaluating greater remains necessary. While budgets have been under scrutiny recent years, indirect costs not quantified any major program, but may constitute an additional avenue to identify...

Mean active degree is an important proxy measure of cross-sectional network connectivity commonly used in HIV/sexually transmitted infection epidemiology research. No current studies have compared measurement methods mean using a study design for men who sex with (MSM) the United States. We estimates based on reported ongoing main and casual sexual partnerships (current method) against dates first last (retrospective method).We data from ARTnet, survey MSM States (2017-2019).

Abstract Background Infectious mononucleosis (IM) is a contagious illness most frequently caused by Epstein-Barr virus (EBV). There are no recent published studies characterizing the burden of IM in general US population over time. Methods Nationally representative samples ambulatory medical care data were utilized to estimate N and proportion visits with an diagnosis (based on ICD-9/10 codes) time period. The National Ambulatory Medical Care Survey (NAMCS: 2006–2015) Hospital (NHAMCS:...
