Fighting AIDS in Cambodia: A Story of Progress and Perseverance

Introduction

Cambodia’s struggle against AIDS stands as a significant example of focused commitment and rapid progress, even in the face of considerable odds. Once among Asia’s countries most affected by HIV/AIDS, Cambodia has now become a regional leader in treatment coverage, prevention measures, and innovation in public health strategy. The nation’s story is one of collaboration between government, community organizations, and international partners—a model that provides hope not just for Southeast Asia, but for global efforts to bring the AIDS epidemic to an end.

The Early Years: Crisis and Transformation

In the mid-1990s, Cambodia faced an HIV prevalence exceeding 2% among adults—a rate considered a grave public health emergency. Epidemic spread was driven by high-risk behaviors within certain populations, including sex workers, men who have sex with men, and intravenous drug users. Efforts by the Royal Government of Cambodia, supported by partners such as UNAIDS and community NGOs like KHANA, began to turn the tide through targeted prevention campaigns, education, and increased access to antiretroviral therapy (ART).

Achievements: Meeting Global Targets and Beyond

95-95-95 Goals

Cambodia is on track to achieve the UNAIDS 95-95-95 targets, a global framework meaning 95% of people living with HIV know their status, 95% of those diagnosed are on ART, and 95% of those on treatment are virally suppressed (meaning the virus is undetectable and untransmissible). As of mid-2025:

92% of Cambodians living with HIV are aware of their status.
Nearly 100% of those diagnosed are receiving antiretroviral treatment.
Over 98% of treated individuals achieve viral suppression.

Sharp Reduction in New Infections

Since 2010, Cambodia’s annual rate of new HIV infections has fallen by 45%, with numbers dropping from 15,000 in the 1990s to around 1,400 by 2022 and 1,200 estimated in 2024. This decline is more than three times faster than the Asia-Pacific average, illustrating the country’s prevention strategies’ effectiveness.

Innovation in Prevention

Cambodia leads the region in offering a diverse range of HIV prevention options, making prevention more accessible and reducing stigma.

Pre-Exposure Prophylaxis (PrEP): Daily oral PrEP has long been available, but the recent rollout of long-acting injectable Cabotegravir (CAB-LA) offers two months’ protection with a single injection. This new option, the first in Asia-Pacific, helps people at high risk—like sex workers, men who have sex with men, and transgender individuals—access convenient, private protection.
Upcoming Innovations: The coming introduction of the Dapivirine Vaginal Ring will expand options for women seeking prevention, further supporting Cambodia’s drive toward zero transmissions.

Community-Led Approaches and Social Protection

Community engagement is central to Cambodia’s strategy:

Peer-led voluntary counseling, testing, and treatment support ensures that even marginalized groups are reached.
Integrated clinics provide HIV services alongside mental health and other social needs, promoting holistic care.
The National Social Security Fund (NSSF) supports impoverished people living with HIV/AIDS, guaranteeing consistent ART access and basic needs.

Ongoing Challenges

Despite Cambodia’s achievements, the fight is not over:

New infections remain concentrated in key populations, with young people (15–24), men who have sex with men, and transgender women at highest risk.
Stigma, discrimination, and poverty continue to affect vulnerable communities.
Sustaining progress requires ongoing financial commitment, including increased domestic funding and continued partnership with international donors.

Government Leadership and International Support

Top-level support, including leadership from the Prime Minister and ministries of health and social affairs, has underpinned Cambodia’s AIDS response. Recent agreements with UNAIDS included a $100,000 commitment for 2025—both a symbolic and practical gesture reinforcing Cambodia’s willingness to fund and lead its own response.

International organizations—such as UNAIDS, WHO, and CDC—continue to provide technical, financial, and operational support, ensuring that Cambodia remains on a trajectory towards elimination.

Lessons for the Region and the World

Cambodia’s example shows that even low- and middle-income countries can control major epidemics through a combination of:

Political will and decisive policy.
Community leadership and involvement.
Access to innovative treatments and prevention tools.
Addressing the broader needs of affected communities through social protection and health systems strengthening.

Looking Forward: The Last Mile

The final phase of AIDS control in Cambodia will require deeper inclusion of at-risk groups, ongoing innovation in services, and breaking down the remaining barriers of stigma and discrimination. Scaling up long-acting PrEP and introducing new prevention technologies will be crucial. Continued investment, both from authorities and international partners, is essential to ensure the gains made are not lost and that Cambodia reaches the point where new infections and AIDS-related deaths become truly rare.

Conclusion

From crisis to near control, Cambodia’s fight against AIDS embodies resilience, innovation, and human solidarity. As Cambodia inches closer to its goal of ending AIDS as a public health threat, it offers inspiration and practical lessons for communities and nations everywhere committed to ending the epidemic.
