While working on my book Nurse: A World of Care, which is about the connections between nurses and global health issues, I visited the Phu Trung Clinic in Saigon, Vietnam. Nurses at the clinic, which is underwritten by the Catholic church, work with AIDS patients and administer tests for the condition. This picture shows the moment when one of the clients I photographed received the news that she was HIV positive. I usually ask permission before photographing, especially in sensitive situations. I am both grateful and amazed that people are willing to share their stories, even painful ones like this.
