Objective: To estimate HIV seroprevalence and the acceptance of voluntary HIV testing among male inmates entering the Wisconsin Correctional System during July 1, 1994-June 30, 1995, and compare these estimates with similar data obtained in 1987-1988.
Methods: A blinded HIV seroprevalence survey concurrent with a review of voluntary HIV antibody testing records.
Results: HIV test results were obtained for 3,681 (89%) male prison entrants during the study period; 26 (0.7%) were HIV-1 seropositive. Based on this estimate and the total number of male prison entrants (4,134), an estimated 29 HIV-1 seropositive male inmates entered the Wisconsin Correctional System during the study period. Eighty-four percent of all inmates were tested voluntarily. Among inmates testing HIV-1 seropositive, 69% were tested voluntarily.
Conclusions: These data suggest that HIV-1 seroprevalence among male prison inmates in Wisconsin is low, and is unchanged from the late 1980s; however, a large increase in the prison population has resulted in a substantial increase in the absolute number of HIV-1 seropositive inmates entering the correctional system. Although overall acceptance of voluntary HIV testing is high, nearly one third of HIV-1 seropositive inmates declined voluntary HIV testing.

Introduction: Chronic immune activation is a hallmark of human immunodeficiency virus (HIV) infection that significantly impacts disease pathogenesis. However, in-depth studies characterizing the immunological landscape of the ectocervix during chronic HIV infection remain scarce despite the importance of this tissue site for HIV transmission.
Methods: Ectocervical tissue samples were obtained from antiretroviral-naïve HIV-seropositive and -seronegative Kenyan female sex workers.

COVID-19 remains a global public health issue and an improved understanding of vaccine performance in immunocompromised individuals, including people living with HIV (PLWH), is needed. Initial data from the present study's pre-crossover/booster phase were previously reported. This phase 2a/b clinical trial in South Africa (2019nCoV-501/NCT04533399) revisits 1:1 randomly assigned HIV-negative adults (18-84 years) and medically stable PLWH (18-64 years) who previously received two NVX-CoV2373 doses (5 μg recombinant Spike protein with 50 μg Matrix-M™ adjuvant) or placebo.

Chronic systemic immune activation significantly influences human immunodeficiency virus (HIV) disease progression. Despite evidence of a pro-inflammatory environment in the genital tract of HIV-infected women, comprehensive investigations into cervical tissue from this region remain limited. Similarly, the consequences of chronic HIV infection on the integrity of the female genital epithelium are poorly understood, despite its importance in HIV transmission and replication.

Unlabelled: Cytomegalovirus (CMV)-seropositive adults have large T cell responses to a wide range of CMV proteins; these responses have been associated with chronic inflammation and frailty in people with or without HIV infection. We analyzed the relationships between chronic HIV infection, frailty, and the breadth and polyfunctionality of CD4 and CD8 T cell responses to CMV. Peripheral blood mononuclear cells from 42 men (20 without HIV and 22 with virologically suppressed HIV) in the Multicenter AIDS Cohort Study (MACS) were stimulated with peptide pools spanning 19 CMV open reading frames (ORFs).
