JOBURE DE GUAYO, Venezuela – After the other villagers had drifted away to do chores, Rafael Pequeño found himself alone with the headman and opened his notebook.
It had been two years since Pequeño, a nurse, had visited this poor indigenous village in Venezuela's remote Orinoco Delta region. His notebook contained a registry of patients in an HIV treatment program that, like the rest of the nation's public health system, had fallen apart. Pequeño took a roll call.
"Armando Beria," he said.
"Still here," replied the headman, Ramón Quintín.
"Ebelio Quinino," the nurse said.
"Still here."
"Mario Navarro."
"Dead."
