Chia Samuen, was 36 years old and severely ill with AIDS when this picture was taken. His wife who was caring for him said that Chia Samuen, had been a very powerful and brave man who worked as a deminer of landmines. When the CHC Team met him he also had TB of the lungs and abdomen and a diffuse and very itchy skin condition associated with AIDS. While MSF (Medicines sans Fronteires)-France had begun a pioneering HIV treatment program offering HIV/AIDS treatment in Phnom Penh, early-on they did not accept patients who also had TB, so Chia Samuen had been transferred to the Pulmonary Ward of the Khmer-Soviet Friendship Hospital. He received TB treatment and palliative care and died shortly after this picture was taken. Chia Samouen and his wife gave permission for his photo to be shown and his story to be shared.

Bringing Life-Saving HIV Treatment to Cambodia

In the early 2000s, AIDS was a death sentence in Cambodia. While lifesaving antiretroviral therapy (ART) had been available in the U.S. and Europe since 1996, it remained out of reach in Cambodia for nearly a decade more—even as HIV rapidly spread, especially in Phnom Penh.

CHC recognized the warning signs early. Knowing the link between rising TB and HIV, CHC began screening all TB patients for HIV in Svay Rieng and launched HIV prevention programs in the late 1990s.

In 2003, with support from Joe and Jeanne Sullivan, CHC brought the first HIV medications to rural Cambodia, providing access to care for 100 patients and opening the first HIV clinic at Svay Rieng Hospital. In 2005, this expanded to Kompong Trach Hospital in Kompot, in partnership with the Cambodian National AIDS Program.

In parallel, CHC helped bring lifesaving HIV treatment and improved HIV and TB/HIV care to 661 people living with HIV/AIDS and TB co-infection at 5 major sites throughout Cambodia through training and care from the CAMELIA Trial (see below).

CHC’s HIV/AIDS Impact: 2003–2024

  1. Over 6,000 patients living with HIV/AIDS have been treated in the CHC rural HIV programs in Svay Rieng and Kompot between 2003-2024.

  2. In 2025, CHC cares for 6,217 patients living with HIV/AIDS: 2,481 adults and children who continue treatment in the Svay Rieng and Kompot clinics (1,299 in Svay Rieng; 1,182 in Kompot), and 3,736 patients at Phnom Penh’s National AIDS Program (NCHADS) HIV clinic.

  3. CHC renovated the Pulmonary Ward at Khmer Soviet Friendship Hospital (KFSH) in Phnom Penh and established HIV/TB care there—and created of the Sullivan Pediatric HIV Clinic (add hyperlink).

  1. CHC was a leader of the CAMELIA trial, which proved that early treatment of HIV improves survival by 34% in TB/HIV co-infected patients. These results, published in the New England Journal of Medicine, shaped global WHO guidelines and have saved an estimated 150,000 lives per year worldwide since 2011 or +1 million lives.

  2. In 2003, CHC partnered with photojournalist James Nachtwey to document the human toll of TB/HIV. These images brought global attention to the crisis of TB/HIV co-infection and catalyzed scientific focus on TB/HIV .

Initiating treatment for HIV and TB/HIV in rural Cambodia:

Phuern

Sarady

Pheurn was the first patient to receive antiretroviral therapy in rural Cambodia in December 2003, shown with his wife in the photos above left and middle. Pheurn presented to the CHC team with TB and was found to be HIV positive. He was cured of TB and has been faithfully taking HIV treatment for the past 21 years and was able to work until his recent retirement at age 63.

Sarady, pictured above (photo above left) at age 33 in 2004 with Dr. Didier Laureillard, CHC and CAMELIA medical Coordinator at the time. She was in the first group of patients to receive antiretroviral HIV treatment from CHC in 2003/2004. She came to CHC with severe painful itching and was found to have a skin condition called PPE (Painful Pruritic Eruption) that is a sign of advanced AIDS (photos above left and right). She told us that she had lost her husband and baby to AIDS the previous year when there were no HIV drugs available to treat them in Cambodia.

Photo to the right shows Sarady, now 55 years old, on Oct. 31, 2024 with Dr. Sun Sath who is CHC’s Manager of the Svay Rieng ART Clinic where access to HIV drugs was initiated in 2003 by CHC. Saraday recently retired from her work as a secretary and now volunteers at the Buddhist Temple in Svay Rieng. Dr. Sun Sath, was trained as a TB medic in the American Refugee Committee TB program on the Thai-Cambodian border when he was a refugee and has been working with CHC since its founding in 1994.

A match made in hell: TB and HIV/AIDS together

Tuberculosis (TB) is the leading cause of death among people living with HIV/AIDS. Although it is curable—even in advanced AIDS—TB has caused up to half of all AIDS-related deaths, accounting for tens of millions of lives lost.

As HIV weakens the immune system, TB is more easily reactivated in those who may have been infected with TB decades before or it can be transmitted much easier to a person living with HIV/AIDS because their immune system is weak. TB aggressively spreads in someone with a weak immune system and the intense inflammation that TB causes also promotes HIV progression and AIDS. Yet with timely diagnosis and treatment, TB can be cured—even in the sickest patients.

While there is still no cure for HIV it can be treated, but TB is curable. Too many people with HIV die from TB, a disease we know how to cure. CHC sought to change that.

The Pulmonary Ward at the Khmer-Soviet Friendship Hospital, the largest public hospital in Cambodia. TB was and continues to be the largest cause of death in patients who have HIV/AIDS around the world.

In Cambodia’s capital city of Phnom Penh The Pulmonary Ward of the Khmer Soviet Hospital was where patients very sick with AIDS and TB were sent in the early 2000s, which had few resources. There were no medications for HIV in 2001 in Cambodia, which is critical to survive TB and HIV co-infection. Left photo: A 17 year old commercial sex worker with AIDS hospitalized on the Pulmonary Ward at the Khmer Soviet Friendship Hospital (KSFH) in 2001. Orphaned and living with her aunt’s family, she had been sold at the age of 12. There were no HIV medications in Cambodia in 2001 and the ward was poorly maintained with few medical services. Maryknoll was providing pain medications, social and food support and helping to clean the ward. Right Photo: A view of the Pulmonary Ward in 2004 after it had been cleaned, prior to its renovation.

Access to Treatment, Treatment Through Science

To bring lifesaving HIV treatment to Cambodia, CHC also turned to science.

In partnership with Cambodian, French, and U.S. researchers—and backed by the NIH, French AIDS Agency, and Institut Pasteur du Cambodge—CHC co-led a clinical trial, asking a question with global stakes: could starting HIV treatment earlier during TB care save more lives? At the same time, the team knew that this study would bring life-saving HIV treatment for each of the 661 participants in the trial at a time when HIV treatment was still not available in Cambodia.

At that time, global norms delayed starting HIV treatment for 2 months after starting TB medicines, even though many patients died from TB while waiting; in fact, 20% of patients who had AIDS and TB, died in that 2 month window.

CHC helped design and run a randomized trial clinical proving that just by starting the AIDS drugs at 2 weeks after TB treatment started compared to the recommended delay of 2 months, survival was dramatically increased (by 34%!)—a result that changed World Health Organization guidelines and to have saved over 150,000 lives globally each year, or +1 million lives since 2011. This trial was called the CAMELIA trial for Cambodian Early vs Late Introduction of Antivirals and the results were published in the New England Journal of Medicine in 2011.

CHC also recognized the trial’s potential to unlock deeper scientific insight. Working with Institut Pasteur (Cambodia and Paris) and Harvard Medical School, and funded by the Annenberg Foundation, John Moores, the NIH and French AIDS Agency, CHC helped uncover how specific immune cells shape outcomes in TB/HIV patients—discoveries that are now guiding new approaches to diagnosis and care.

To conduct the trial, CHC built six Centers of Excellence across Cambodia, including the Pulmonary Ward at the Khmer Soviet Friendship Hospital and the HIV service at Svay Rieng Provincial Hospital, and not only delivered life-saving care to 661 patients during the trial, but also laid the foundation for nationwide HIV and TB/HIV treatment. These efforts brought cutting-edge medicine to patients who had been left behind—and ultimately reshaped global standards of care.

With support from the Japanese Embassy Grass Roots Fund, CHC renovated the Pulmonary Ward of the Khmer Soviet Friendship Hospital (KFSH), which would ultimately serve as the major clinical site of the CAMELIA trial. The ward became a Center of Excellence for TB and HIV Care and Research in the country and became a teaching ward for Cambodian medical students, nurses, and residents-in-training for TB, HIV/AIDS, and TB/HIV co-infection.

Chouet Sarun, the CHC manager of the Pulmonary Ward at KFSH during the CAMELIA trial (2006-2010). is pictured on the renovated ward in 2006. Sarun was also a graduate of the ARC Refugee Camp medical training program on the Thai-Cambodian border when he was a refugee. Right photo: A mother cares for her daughter suffering from advanced AIDS and TB on the newly renovated Pulmonary Ward.

This 28 year old woman who was in the CAMELIA trial had advanced HIV disease and TB (Left photo above). She was started on TB and HIV treatment on Dec 4, 2007. After cure of her TB and successful treatment of her HIV, she was hired to patient supporter working for the CAMELIA trial on the Pulmonary Ward at the Khmer-Soviet Friendship Hospital (see photo above right). She is pictured on Oct. 17, 2008 with Dr. Sarin Chan who was a medical coordinator of the CAMELIA trial feeling well again on stable HIV medications looking at her picture on teh computer from when she was ill.

Showing the toll of TB/HIV through photography: healing access to care

TB is the leading cause of death among people living with HIV, responsible for up to half of all AIDS deaths since the start of the pandemic. To raise global awareness and push for access to life-saving TB, DR-TB, and HIV treatments, we partnered with Time Magazine war photographer James Nachtwey beginning in 2003 to document the human toll of these diseases in Cambodia displayed in his series, which won Photographer of the Year for his photo essay entitled Defying the Dynamic of Neglect-TB in Cambodia. The collaboration led to publication of Nachtwey’s photos showing the human face of TB, DR-TB and AIDS twice in Time Magazine, and to their display in major exhibits at the United Nations (New York), Le Laboratoire (Paris), the Max Planck Institute (Berlin), the Gates Grand Challenge Conference (Bangkok), the U.S. Capitol, and for Nachtwey’s TED Prize, all of which elevated the public and scientific consciousness of TB and HIV and TB/HIV co-infection as a humanitarian emergency.

In parallel, CHC helped initiate the first combined TB/HIV sessions at the International AIDS Society Meeting (2004), which are still ongoing and the TB/HIV Keystone Symposium in Tanzania linked with the Gates Grand Challenges Meeting—all of which bridged previous gaps in the global scientific collaborative response to TB/HIV co-infection and highlighted the necessity of collaboration between the TB and HIV fields in both research and care.
