However, comprehensive data on their epidemiological and economic burden and long-term trends in this population are limited. This study aims to systematically assess the global, regional, and national burden and temporal trends of HIV/AIDS and other significant STIs among WCBA from 1990 to 2021, and to evaluate the associated economic burden in 2021. Data were obtained from the Global Burden of Disease Study 2021 to estimate the incidence, prevalence, mortality, and disability-adjusted life years (DALYs) for HIV/AIDS and other STIs across 204 countries or territories. Temporal trends were assessed using estimated annual percentage change (EAPC). An age-period-cohort model was applied to estimate relative risks, and frontier analysis was used to determine efficiency in resource utilization. The economic burden in 2021 was estimated using an indirect cost approach. In 2021, an estimated 287 million incident cases of HIV/AIDS and other STIs occurred globally. Since 1990, new HIV/AIDS cases have declined by 25.1%, and the age-standardized incidence rate (ASIR) decreased by 46.5%, while the age-standardized prevalence rate (ASPR), age-standardized mortality rate (ASMR), and age-standardized DALYs rate (ASDR) increased. In contrast, other STIs saw a 54.3% rise in incident cases, with slight increases in ASIR and ASPR, and decreases in ASMR and ASDR. The burden was highest in low sociodemographic index (SDI) regions and declined with increasing SDI. Sub-Saharan Africa remained the most affected region. Global direct healthcare spending on HIV/AIDS and other STIs among WCBA reached $2.46 billion in 2021, with high-SDI countries accounting for the majority. Low-SDI countries, despite high disease burdens, contributed minimally to global spending. From 1990 to 2021, the burden of HIV/AIDS and other STIs among WCBA increased significantly, with notable regional disparities. Sub-Saharan Africa carries a disproportionately high burden of HIV/AIDS and other STIs yet receives insufficient global attention. Low-SDI populations face greater disease burdens but benefit from less healthcare investment, underscoring the urgent need to strengthen STIs-specific prevention, treatment, and health education in these regions.</p>\u0000 </section>\u0000 </div>","PeriodicalId":16354,"journal":{"name":"Journal of Medical Virology","volume":"97 9","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145033500","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although formula feeding reduces breastfeeding-associated transmission, MTCT still occurs, implicating pregnancy or delivery as key transmission windows. In this study, placental tissues from nine HTLV-1–positive mothers were analyzed using DNA/RNAscope, revealing low HTLV-1 DNA and RNA levels and a low RNA/DNA ratio, consistent with latent infection in the placenta and potentially explaining the low MTCT rate. Elevated interferon (IFN)-β levels were observed in infected placentas compared to seronegative controls, while IFNα, IFNγ, and IFITM expression remained unchanged. Concurrently, sustained IFNβ expression in infected placentas suggests its dual roles in HTLV-1 pathogenesis: suppressing viral replication while potentially disrupting placental homeostasis through chronic inflammation. In vitro modeling using BeWo cells or primary trophoblasts cocultured with HTLV-1-infected MT-2 cells demonstrated syncytin-1-mediated viral entry, confirmed by HTLV-1 p19 detection in both trophoblasts. Of note, HTLV-1 transmission was abolished by a syncytin-1-specific fusion inhibitor HRB1, underscoring syncytin-1's essential role in cell-to-cell transmission of HTLV-1. Thus, this study identifies syncytin-1 as a therapeutic target to block vertical transmission and highlights the need to balance antiviral responses with placental integrity in HTLV-1 management.</p>","PeriodicalId":16354,"journal":{"name":"Journal of Medical Virology","volume":"97 9","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/jmv.70585","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144998695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
