Abstract

HIV/AIDS remains one of the most challenging and persistent public health concerns in the 21st century. Asia, as the world’s most populous continent, bears a significant portion of this burden, with over 6.8 million people living with HIV as of 2024, according to UNAIDS. Despite substantial progress in diagnosis, treatment, and prevention, the epidemic continues to affect millions of individuals, especially those in marginalized or high-risk communities. This paper provides a detailed exploration of HIV prevalence across Asia, emphasizing the epidemiological patterns, risk factors, socio-economic and cultural determinants, and regional responses to the epidemic. Data were derived from authoritative sources such as WHO and UNAIDS reports, complemented by country-specific case studies. Findings reveal disparities in infection rates, healthcare access, and ART coverage across different Asian regions. The discussion underscores the role of stigma, gender inequality, political will, and healthcare infrastructure in influencing outcomes. The paper concludes by recommending targeted interventions, regional cooperation, and policy reforms to accelerate progress toward the global goal of ending AIDS by 2030.

Introduction

The Human Immunodeficiency Virus (HIV) epidemic continues to be a complex and evolving challenge for global public health. Although Asia’s overall HIV prevalence is lower compared to sub-Saharan Africa, the region’s large population means that millions remain affected, creating a substantial socio-economic and healthcare burden. In 2023, approximately 6.7 million people were living with HIV in Asia and the Pacific, with 290,000 new infections and about 145,000 AIDS-related deaths. The epidemic is characterized by uneven geographical distribution, driven by diverse socio-economic, cultural, and behavioral factors.

Key populations—men who have sex with men (MSM), people who inject drugs (PWID), sex workers, and transgender individuals—continue to experience disproportionate HIV risk. In many Asian societies, deep-rooted stigma and discrimination hinder access to healthcare, prevent individuals from seeking testing, and contribute to underreporting of cases. Furthermore, the rapid urbanization, labor migration, and insufficient sex education in several countries have exacerbated HIV vulnerability among youth populations.

This study aims to provide an in-depth overview of HIV infection prevalence in Asia, focusing on patterns, determinants, and policy responses. The analysis also explores progress toward global targets such as the UNAIDS 95-95-95 initiative, which envisions 95% of people living with HIV knowing their status, 95% of those diagnosed on treatment, and 95% of those on treatment achieving viral suppression.

Methodology

This study adopted a mixed-methods research design, utilizing both quantitative and qualitative analyses. Epidemiological data were obtained from UNAIDS Global AIDS Reports (2023–2024), WHO HIV Surveillance Reports, and peer-reviewed articles published between 2018 and 2024. The research also integrated case studies from India, Thailand, Indonesia, China, and Pakistan to reflect regional variations. Literature was sourced through databases including PubMed, Scopus, and Google Scholar, using keywords such as ‘HIV prevalence Asia,’ ‘ART coverage,’ ‘HIV key populations,’ and ‘epidemiology of HIV in Asia.’

Data were analyzed descriptively to identify trends in prevalence, incidence, and mortality. Comparative analysis was performed between subregions (South, Southeast, East, and Central Asia) to highlight disparities. Qualitative synthesis focused on socio-economic and policy-related factors influencing HIV transmission and healthcare access. Limitations included inconsistent surveillance systems, underreporting, and lack of uniform testing coverage across countries. Nevertheless, triangulation of multiple data sources enhanced validity.

Results

The analysis revealed significant heterogeneity in HIV prevalence across Asia. India remains the country with the highest number of people living with HIV—approximately 2.4 million individuals, representing around 35% of the regional total. Adult prevalence stands at 0.2%, with new infections declining due to sustained prevention and treatment efforts. Thailand, once the epicenter of Asia’s epidemic, has reduced prevalence to 1.1% through comprehensive prevention programs, widespread ART access, and strong political leadership. Indonesia, on the other hand, continues to report rising infection rates—particularly among PWID and youth populations—due to fragmented healthcare infrastructure and inadequate harm-reduction measures.

China’s epidemic, though relatively smaller in proportion, has shifted toward MSM communities and urban youth. Nationwide ART coverage has increased substantially; however, stigma and fear of social discrimination persist as major deterrents to testing. In Pakistan, the epidemic is concentrated among key populations, particularly PWID, where HIV prevalence exceeds 25% in some provinces. Limited awareness, inadequate testing, and underfunded harm-reduction programs have contributed to this alarming trend.

According to WHO data (2024), sexual transmission accounts for roughly 78% of all HIV infections across Asia, followed by transmission through injecting drug use (15%) and mother-to-child transmission (5%). Over the past decade, regional ART coverage has improved dramatically, with countries such as Thailand and Cambodia achieving over 80% ART coverage. However, other nations—like Indonesia and Pakistan—remain below 50%, highlighting the persistent inequalities in healthcare access.

Discussion

The HIV epidemic in Asia reflects the intricate interplay of biomedical, socio-cultural, and structural factors. The success of HIV control strategies depends not only on clinical interventions but also on addressing underlying social determinants of health. Societal stigma, gender inequality, and restrictive legal frameworks remain barriers to universal testing and treatment coverage. Countries with supportive policy environments and community-driven programs—such as Thailand and Cambodia—have shown significant progress in reducing new infections and AIDS-related deaths.

The emergence of the COVID-19 pandemic also disrupted HIV service delivery across many Asian countries. Lockdowns and health system strain led to temporary declines in ART adherence and HIV testing rates. In response, several governments and NGOs introduced telemedicine, community dispensing models, and home-based testing to mitigate these effects. This shift demonstrated the resilience of healthcare systems and the potential for digital health solutions in sustaining HIV care continuity.

Gender inequality remains another major factor influencing HIV transmission. Women, especially in South and Southeast Asia, face biological and socio-economic vulnerabilities that increase their risk. Gender-based violence, lack of negotiation power, and limited access to reproductive health services exacerbate this issue. Adolescent girls and young women account for nearly 25% of new infections in some regions. Programs such as the Global Fund’s gender-sensitive initiatives have been pivotal in addressing these disparities.

Youth populations also represent a growing concern. With increased exposure to social media, urban migration, and limited sexual health education, young people are at risk of acquiring HIV. Integrating HIV awareness into school curricula, expanding peer-education networks, and promoting online campaigns can significantly improve awareness and prevention outcomes.

Community-based organizations (CBOs) and NGOs play a crucial role in HIV prevention and treatment across Asia. In India, networks such as the National AIDS Control Organisation (NACO) have effectively mobilized grassroots interventions. In Thailand, the collaboration between civil society and government institutions has been instrumental in ensuring ART accessibility and reducing stigma. Conversely, in countries like Pakistan and Indonesia, restrictive policies limit the operational scope of NGOs, thereby impeding progress.

The 95-95-95 targets remain a global benchmark for evaluating progress. As of 2023, Thailand had achieved approximately 94-93-90, while India reached 88-86-82, and Indonesia lagged at 70-60-55. Closing these gaps requires not only medical interventions but also the strengthening of community systems, financing, and data-driven monitoring.

Conclusion

In conclusion, HIV/AIDS in Asia presents a mosaic of progress and persistent challenges. While remarkable gains have been made in reducing new infections and expanding ART coverage, inequalities in access, stigma, and health infrastructure remain major obstacles. Achieving the goal of ending AIDS by 2030 requires a multidimensional strategy—one that integrates biomedical, behavioral, and structural interventions. Governments must continue to prioritize HIV funding within national budgets, strengthen surveillance systems, and ensure the inclusion of marginalized groups in all health programs.

Moreover, expanding youth and gender-sensitive education, leveraging digital technologies for outreach, and fostering cross-border collaboration will be essential to sustaining momentum. Only through sustained political will, evidence-based policy, and community engagement can Asia move closer to eliminating HIV/AIDS as a public health threat in the coming decade.
