Drawing on hospital and cemetery records, censuses, diagnoses, newspaper accounts, and interviews, Zulawski describes the major medical problems that Bolivia faced during the first half of the twentieth century, their social and economic causes, and efforts at their amelioration. Her analysis encompasses the Rockefeller Foundation’s campaign against yellow fever, the almost total collapse of Bolivia’s health care system during the disastrous Chaco War with Paraguay (1932–35), an assessment of women’s health in light of their socioeconomic realities, and a look at Manicomio Pacheco, the national mental hospital.
