Abstract

Summary: Background: The cost of population-based surveys is high and obtaining funding for a national population-based survey may take several years, with follow-up surveys taking up to five years. Survey-based prevalence estimates are prone to bias owing to survey non-participation, as not all individuals eligible to participate in a survey may be reached, and some of those who are contacted do not consent to HIV testing. This study describes how Bayesian statistical modeling may be used to estimate HIV prevalence at the state level in a reliable and timely manner. Methods: We analysed national HIV testing services (HTS) data for Nigeria from October 1, 2020, to September 30, 2021, to derive state-level HIV seropositivity rates. We used a Bayesian linear model with normal prior distribution and Markov Chain Monte Carlo approach to estimate HIV state-level prevalence for the 36 states +1 FCT in Nigeria. Our outcome variable was the HIV seropositivity rates and we adjusted for demographic, economic, biological, and societal covariates collected from the 2018 Nigeria HIV/AIDS Indicator and Impact Survey (NAIIS), 2018 Nigeria Demographic and Health Survey (NDHS) and 2016-17 Multiple Indicator Cluster Surveys (MICS). The estimated population of 15–49 years olds in each state was multiplied by estimates from the estimated prevalence to generate state-level HIV burden. Findings: Our estimated national HIV prevalence was 2.1% (95% CI: 1.5–2.7%) among adults aged 15–49 years in Nigeria, which corresponds to approximately 2 million people living with HIV, compared to previous national HIV prevalence estimates of 1.4% from the 2018 NAIIS and UNAIDS estimation and projection package PLHIV estimation of 1.8 million in 2022. Our modelled HIV prevalence in Nigeria varies by state, with Benue (5.7%, 95% CI: 5.0–6.3) having the highest prevalence, followed by Rivers (5.2%, 95% CI: 4.6–5.8%), Akwa Ibom (3.5%, 95% CI: 2.9–4.1%), Edo (3.4%, 95% CI: 2.9–4.0%) and Taraba (3.0%, 95% CI: 2.6–3.7%) placing fourth and fifth, respectively. Jigawa had the lowest HIV prevalence (0.3%), which was consistent with prior estimates. Interpretation: This model provides a comprehensive and flexible use of evidence to estimate state-level HIV seroprevalence for Nigeria using program data and adjusting for explanatory variables. Thus, investment in program data for HIV surveillance will provide reliable estimates for HIV sub-national monitoring and improve planning and interventions for epidemiologic control. Funding: This article was made possible by the support of the American people through the United States Agency for International Development (USAID) under the U.S. President's Emergency Plan for AIDS Relief (PEPFAR).

2. A review of current trends in HIV epidemiology, surveillance, and control in Nigeria.

Author

Bassey AE and Miteu GD

Abstract

The HIV epidemic remains a public health challenge in Nigeria, with about 1.9 million people living with the virus in 2020. Despite progress in controlling the epidemic, challenges remain, including inadequate funding and limited access to prevention and treatment services for key populations. This article provides an overview of the HIV control system in Nigeria and the current state of the HIV control system in Nigeria. It provides recommendations for strengthening the response to the epidemic. Contributions of government agencies, international partners, and civil society organizations are required to reduce this epidemic. This article highlights the need to strengthen surveillance systems, increase access to testing and treatment, enhance prevention strategies, address stigma and discrimination, increase funding, and expand research and development. The impact of antiretroviral therapy on HIV management is also discussed. Over the last decade, Nigeria has made significant progress in controlling the HIV epidemic, with a decline in new infections and increased treatment coverage. However, more work is needed to achieve the 95-95-95 targets set by the joint united nations programme on HIV/acquired immunodeficiency syndrome for 2030, and a multi-pronged approach is required to address the social and structural determinants of health that drive the epidemic. By implementing the recommendations outlined in this article, Nigeria can make significant progress towards ending the HIV epidemic and improving the quality of life for those living with the virus., Competing Interests: The authors declare no conflict of interest., (Copyright © 2023 the Author(s).

Abstract

This book delves into the combination of factors that make Argentina a success story in combating HIV/AIDS. It analyzes the national and inter-provincial burden of disease, the demographics of new HIV cases, the demand and supply-sides of service delivery, and conducts a cost-benefit analysis of the Argentine National HIV/AIDS Program from 2000 to 2010. This book will be of interest to those who wish to examine key programmatic innovations that have been essential to Argentina’s success in the fight against HIV/AIDS, such as the introduction of universal free antiretroviral treatment, a comprehensive legal framework for sexual and reproductive rights, the introduction of incentives and results-based financing in the HIV/AIDS program, electronic monitoring of supplies and medicines, and implementation of an electronic clinical governance system for improving the quality of care and patient follow-up. The 1992 creation of the National HIV/AIDS Program was a fundamental step for Argentina to reach the second lowest burden of HIV/AIDS in South America in 2010. Despite these successes, the fight against the HIV/AIDS epidemic in Argentina still poses continuous challenges, including a high number of new infections among young men who have sex with men, inequalities in HIV/AIDS rates between provinces, insufficient coverage of HIV diagnostic testing, relatively low expenditure on HIV prevention, and poses the question regarding the long-term financial sustainability of the program, considering the increasing number of patients in treatment and the high comparative cost of antiretroviral treatment.

Abstract

Background: The sustainable development goals (SDGs) aim to end HIV/AIDS as a public health threat by 2030. Understanding the current state of the HIV epidemic and its change over time is essential to this effort. This study assesses the current sex-specific HIV burden in 204 countries and territories and measures progress in the control of the epidemic. Methods: To estimate age-specific and sex-specific trends in 48 of 204 countries, we extended the Estimation and Projection Package Age-Sex Model to also implement the spectrum paediatric model. We used this model in cases where age and sex specific HIV-seroprevalence surveys and antenatal care-clinic sentinel surveillance data were available. For the remaining 156 of 204 locations, we developed a cohort-incidence bias adjustment to derive incidence as a function of cause-of-death data from vital registration systems. The incidence was input to a custom Spectrum model. To assess progress, we measured the percentage change in incident cases and deaths between 2010 and 2019 (threshold >75% decline), the ratio of incident cases to number of people living with HIV (incidence-to-prevalence ratio threshold
