Working seven days a week, 12 hours a day, Dr. Megan Coffee directs a team of volunteer doctors and Haitian and American nurses who care for a vulnerable population in a country afflicted with the highest TB infection rate in the Western hemisphere. In two portable buildings and a tent surrounded by the ruins of Port-au-Prince, Coffee treats patients diagnosed with both HIV and TB. She -- and a constantly evolving staff of volunteer doctors and physicians -- save lives for pennies a day. I shot the essay with a protective mask. All patients or their relatives granted permission to be photographed. I published this essay at socialdocumentary.net after all of the editors that he contacted at the New York Times magazine replied to his query with "out of the office" messages.
