Public health and social medicine are dynamic and evolving concepts directed towards increasing health and preventing disease in the framework of their so cietal and economical determinants1,2. These determinants include poverty and lack of political representation1,2,3. Latin American public health and social medi cine have a rich and vital tradition from colonial times that is often overlooked4,5. For example, the so-called smallpox vaccine expedition or Balmis’ expedition, which lasted from 1803 to 1811, was one of the first organized public health activities in the Americas.6,7) This expedition, sponsored by the Spanish crown and organized by the Spanish physician F. J. Balmis, transported smallpox vaccine virus across the Atlantic by inoculating the virus into the arms of consecutive children.6,7 The expedition was a success because the vaccine was transported and distributed from Spain to Mexico, South America, Philippines and China.6,7) Public health contents and ideas about hygiene were also found in writings of Latin American physicians such as Eugenio Espejo (1747-1795), a forerunner of Ecuadorian Independence8 and Francisco J. de Caldas (1768-1816) the martyr of Colombia’s Independence. The latter participated in a botanical expedition called the Mutis’ expedition to look for medicinal plants, spe cifically varieties of the antimalarial and anti-inflam matory cinchona9,10.
It was not until the twentieth century that public health and social medicine in Latin America developed sufficiently to permit elaboration of original contribu tions. These were accompanied by the emergence of political and social movements that drove and facilita ted their implementation4,5,11,12. Thus, Salvador Allen de of Chile, influenced by the work of Rudolf Virchow of the previous century, elaborated on the social and economic determinants of health in the 1930s.13-15) Allende, elected president in 1970, attempted to implement policies to improve the health of the Chilean population.13,14 Important nuclei of people working on public health and social medicine emerged similarly in Brazil, Ecuador, Cuba, and Mexico4,5,16. In Mexico, for example, hygienic policies began to be elaborated at the end of the dictatorship of Porfirio Diaz at the turn of the twentieth century17. This process was ac celerated by the Mexican Revolution in 1917 and the creation of a Department of Public Health in charge of vaccination and control of food and drug safety17. The politics of the Mexican Revolution also stimula ted creation of Mexican Social Security, development of rural medicine, implementation of industrial health policies, writing of a Sanitary Code and evolution of environmental sanitation17. The Mexican Institute of Social Security (MISS) was the culmination of these policies which were accompanied by a measurable de crease in morbidity and mortality17.
In this context, it was not unusual that two of the most renowned Mexican artists of the Mexican Revolution, Diego Rivera and David A. Siqueiros, were as ked to paint two murals in the newly constructed Hospital de La Raza belonging to the Mexican Institute of Social Security (MISS) in 195118-21. Rivera’s mural, The History of Medicine in Mexico: The People’s Demand for Better Health, finished in 1953, adopted objects and symbols of the past and adapted them for the modern viewer to tell the history of the evolution of medicine in Mexico (Figure 1). Throughout the mural certain figures and scenes are borrowed from colonial sources18,20 and from the modern present18,20. The main na rrative of the mural was not in the consistent portrayal of factual evidence, in terms of the representation of native healing practices, but rather the representation of Mexican indigenous and modern peoples deman ding medical care and its technology as well as sear ching and implementing community involvement18,21. The mural comprises two well defined sections repre senting modern medicine to the left, and Pre-Colum bian indigenous healing practices to the right which are connected by middle section representing the Aztec deity Tlazolteotl-Ixcuina18,21. For reasons of space, the present analysis of the mural will concentrate on the modern left half.
In the top left-hand corner of this section, the re presentation of the collective force that laid the foundation for the creation of the MISS is portrayed (Figure 2). The group of people who make up the diverse ur ban community of Mexico City is shown gathering for action, demanding access to primary health care18,20. At the head of the line is an anonymous industrial worker dressed in a coral red shirt, blue overalls, and with a bandaged arm leading this group. This grouping can be interpreted as the most compelling piece of commentary about the concept of an institutionalized health care system and the people’s role as participant and conductor of the process to fulfill the essential human right of social security and medical care. Below figures that represent MISS and private business interests, Rivera displayed a family unit participating in the so cial security system. This ‘industrial family’ consists of the father as the laborer, the pregnant wife and mother in the yellow dress, and their two children -a young girl who suffers from polio and a boy dressed in blue overalls holding a toy rifle (Figure 3). Interestingly, the depiction of children expressed Rivera’s connection and loyalty to the dynamic essence of modernization through familiar symbols related to peace and health.
Inclusion of the daughter dressed in a rose-colored dress struggling with polio refers to two important realities that occurred in Rivera’s life. First, the little girl reminds the viewer of the tragic polio epidemic of the 1950s in the United States and Mexico that lead to the introduction of the Salk polio vaccine and its widespread use by 1955. Second, her thinner left leg subtly connects the scene with Rivera’s wife, Frida Kahlo, who suffered all her life with the disease22. Coincidently, the young girl’s brother also incorporates a cautious ges ture, for the boy is drawn facing away from the viewer dressed in the familiar blue overalls that his father wears, as well as what Rivera wore as he worked. The little boy with a toy rifle evokes the spirit of rebellion of the Mexican Revolution, with the gun and blue ove ralls as his symbols of revolt, warning the viewer that one must probably not allow a centralized authority take advantage of the people.
The brother and sister duo represent the presence of the culture and traditions of the present and past rooted in their parents ancestry that will someday be manifested by new traditions due to their own participation in modernity. Rivera’s depiction of the in dustrial family is the embodiment of the struggle for equilibrium between public, private, and institutional forces that demand social healthcare as well as participate in the modern system. Both children of the past and present interacting and becoming part of the es tablished social security system embody the fact that demand for primary healthcare will perpetually be a challenge faced by all. It is the responsibility of a uni ted populace to become aware of centralized entities elected, or selected, that deserve constant monitoring and input from the community. In this manner, the left section of the mural depicting the family unit and the people in need of medical assistance demonstrates a cautiously optimistic portrayal of the fruits of medical technology. Rivera’s commentary to the public appears to propose both an acknowledgement of and critique on the idea of a social security system as a cen tralized institution and the role the citizen, political movements, and community organizations.
The strong historical visual narrative that Rivera used in this mural, specifically in its left half, expresses to the viewer the notion that the people as a collecti ve force are the most significant element of the enti re healthcare system that benefits all. The mural also tells us that the populace and its organizations must be aware of the modern entrenched bureaucracies and political groups that (for different reasons) attempt to block access to widely needed medical care and social security. The focus on the depiction of adults and children as part of the struggle for better health stimulates the notion that for the youth something has to be done in the present to secure their future and that those children are the group most vulnerable to failures in health systems. The portrayal of children also suggests regeneration and that with time, new generations will have the choice to physically manifest what is created in the present. There is no doubt that the message of Rivera in this mural regarding health care for all conti nues to be relevant today in Mexico and the rest of La tin America. In these countries, more than 200 million people are currently without access to medical care, and in coming years, 80 million retirees will increase the numbers of people with limited access to this hu man right23.
