It was 11 on a Tuesday night nearly six years ago when Jean-Clair Desir's mother fell ill with cholera in the Boucan-Carre district of Haiti's central highlands.
"She started vomiting with diarrhea," Desir recalls. "I made oral rehydration for her, nothing worked. She died at 3 in the morning." She never made it to a hospital or clinic and so probably wasn't counted as a cholera victim.
After burying his mother, Desir, a third-year student at Haiti's University of Agronomy Sciences, nearly died of cholera himself.
