Infections and Inequalities

Paul Farmer, a physician and anthropologist who divides his time between Boston and rural Haiti, argues that social inequalities determine who falls ill with infectious diseases and who dies from them. Drawing on fieldwork, clinical practice, and critical reanalysis of published research, he contends that poverty, racism, and gender inequality function as pathogenic forces, shaping the distribution and outcomes of AIDS and tuberculosis far more powerfully than the cultural beliefs or personal behaviors of the afflicted. The book builds its case through patient narratives, epidemiological data, and a sustained critique of the scholarly and policy frameworks that obscure these dynamics.

In a preface written for the paperback edition, Farmer contrasts responses to real and hypothetical epidemics. A young Haitian man died because he lacked four dollars for transportation to a clinic during an anthrax outbreak, while billions were spent in the United States on theoretical bioterrorism preparedness. He details the Joseph family in Port-au-Prince, where Jean Joseph, a 21-year-old student, contracted tuberculosis and failed repeated courses of first-line drugs. His family sold assets to buy second-line medications but could not sustain the cost, and four of Jean's siblings subsequently fell ill with drug-resistant tuberculosis transmitted in their cramped household. Farmer advances five assertions: Treatment cannot remain exclusive to wealthy countries; cost-effectiveness cannot be the sole gauge for public health interventions; AIDS research must include a social-justice component; more effective prevention strategies are needed; and claims about "limited resources" must be challenged.

The book opens with Annette Jean, a young Haitian woman who died of massive hemoptysis, the coughing up of blood caused by tuberculosis, before reaching the clinic. Farmer states the core thesis: Social inequalities shape the distribution and outcome of infectious diseases, and these inequalities are biological in their expression but largely socially determined. He introduces the concept of "immodest claims of causality," explanations that are wrong or misleading and that divert attention from interventions that could save lives. He critiques both anthropology and medicine: anthropology's tendency to mistake structural violence, the historically given and economically driven processes that constrain individual agency, for cultural difference, and medicine's narrow focus on individual patients at the expense of the social forces that generate sickness.

Farmer recounts arriving in Haiti in 1983 at age 20, where preventable deaths led him to specialize in infectious disease. A Haitian priest directed him to conduct a community needs assessment; villagers wanted a hospital, not the "appropriate technology" favored by development experts, which the priest denounced as "good things for rich people and shit for the poor" (21). Farmer helped found the Clinique Bon Sauveur in 1985, along with Zanmi Lasante, a community-based organization in Haiti, and Partners in Health, a Massachusetts-based nongovernmental organization. A colleague's death from multidrug-resistant tuberculosis (MDRTB), a form of the disease resistant to the most effective first-line drugs, acquired in a Peruvian slum drew Partners in Health to Lima, where they documented over a hundred untreated cases. Both Peruvian authorities and the World Health Organization initially declared MDRTB treatment "not cost-effective" in developing countries, but subsequent results proved significantly better than early efforts in U.S. cities.

Farmer develops an analytic framework arguing that diseases long afflicting the poor are considered "new" only when they reach more visible populations. He critiques "tropical medicine" for implying geographic rather than socioeconomic topography and nation-state-based analyses for failing to capture transnational disease dynamics. Using Ebola, tuberculosis, and HIV as case studies, he shows that outbreaks were amplified by poverty, that tuberculosis never disappeared among the poor, and that HIV's early misattribution to Haiti reflected North American folk models rather than sound epidemiology.

Turning to AIDS among women, Farmer notes that a database search combining "AIDS," "women," and "poverty" returned zero results. He presents three cases illustrating structural violence behind women's HIV risk: Darlene Johnson, an African American woman in Harlem who experienced cascading losses when her stepbrother died of AIDS, her stepfather died of a heart attack though found to be HIV-infected, and her husband died of AIDS, followed later by two friends and her infant son; Guylène Adrien, a Haitian peasant driven by poverty into sexual unions that exposed her to HIV; and Lata, an Indian girl sold into prostitution in Bombay at age 15. All three were born into poverty, and their attempts to escape it led to HIV infection.

Farmer traces how the Haitian AIDS epidemic was shaped by transnational economic forces and distorted by exoticizing narratives. The CDC's 1982 classification of Haitians as a risk group devastated Haiti's tourist industry, with annual visitors dropping from 75,000 to under 10,000. Exotic theories persisted in U.S. medical literature, including claims that voodoo rituals or "necromantic zombiists" transmitted HIV. Farmer argues the Caribbean pandemic is best understood as a "West Atlantic pandemic" shaped by trade and labor migration, noting that Cuba, outside this economic system, had negligible HIV prevalence. A case-control study of 25 HIV-positive women in rural Haiti reveals that the chief risk factors were having a partner who was a soldier or truck driver and having worked in Port-au-Prince as a domestic servant, not number of sexual partners or cultural beliefs. In an ethnographic interlude, Farmer reflects on two clinical encounters in which routine biomedical interventions appeared miraculous only because of grossly unequal access to care, arguing that such "miracles" are really reflections of misery. He also traces how villagers in the settlement of Do Kay developed a collective understanding of AIDS between 1983 and 1990, moving from no shared model to a framework incorporating both natural transmission and supernatural causation, with associations linking the disease to North American imperialism and lack of class solidarity.

The book's second half addresses tuberculosis. Farmer presents three cases: Jean Dubuisson, a Haitian peasant whose family sold livestock and land for care he ultimately received too late, leaving him with a destroyed left lung; Corina Bayona, a Peruvian woman with drug-resistant tuberculosis who was shuttled between clinics for six years, branded noncompliant, and died in 1996; and Calvin Loach, an African American Vietnam veteran in Boston whose physician-directed treatment errors led to treatment failure. Farmer shows that tuberculosis has always disproportionately affected the poor and that effective therapy after 1943 only widened the gap between those with and without access.

Results from a community-based program in rural Haiti reinforce this argument. Patients receiving daily home visits, financial aid, and nutritional supplements achieved a 100 percent cure rate after 18 months, while a comparison group receiving the same medications without community supports had a cure rate of at best 48 percent. Whether patients believed sorcery caused their illness showed no correlation with outcomes, contradicting the hypothesis that cultural beliefs drive noncompliance. Farmer's most polemical chapter extends this critique, presenting cases from Haiti and Peru where patients received inappropriate regimens and identifying six myths about MDRTB, including that it is untreatable and primarily caused by patient noncompliance rather than structural barriers and physician error.

The concluding chapter argues that widening inequalities of access to effective therapies constitute the defining moral challenge of modern medicine. Farmer cites research showing that when barriers to care were removed, survival differences between races and genders disappeared. He critiques "compliance screening," in which physicians withheld therapy from poor patients on the grounds that noncompliance might breed resistant strains. He contrasts Gloria, a woman denied a drug trial because of past noncompliance with AZT (which had caused her headaches and anemia), with David Sanford, a Wall Street Journal editor who was himself noncompliant with AZT but adhered to combination therapy. Farmer closes by arguing that inequality itself is the modern plague, noting that Peru spent $350 million on fighter jets while declaring MDRTB treatment unaffordable. The growing gap between rich and poor, both within and between nations, drives the persistence of diseases fully treatable with existing technology.
