Environment and health with respect to a poverty-related disease: the epidemiology of trachoma in Spain, 1925-1941

Trachoma currently represents one of the three main causes of ‘avoidable' blindness and reaches intolerable dimensions in many developing countries. It was endemic in many regions of eastern Spain until well into the twentieth century. The aim of this paper is to analyze the epidemiological development of this disease in contemporary Spain; to examine its determining factors, particularly environmental and sanitary/health factors, and, finally, to study the health care, environmental and socio-economic measures that led to its control and eradication. We believe that the historical approach not only highlights the role of environmental factors in the development of trachoma, but may also aid in understanding the current epidemiology of trachoma.

O tracoma representa hoje uma das três principais causas de cegueira ‘evitável' e tem alcance inaceitável em muitos países em desenvolvimento. Era doença endêmica em muitas regiões da Espanha oriental século XX adentro. O objetivo do presente artigo é analisar o desenvolvimento epidemiológico da doença na Espanha contemporânea; examinar seus fatores determinantes, especialmente os ambientais e sanitários, e, finalmente, estudar as medidas de assistência médica, socioeconômicas e ambientais que levaram a seu controle e erradicação. Acredita-se que a abordagem histórica revela a importância dos fatores ambientais no desenvolvimento do tracoma e ajuda a compreender o perfil epidemiológico atual da doença.
