RESUMENEn la Academia Nacional de Medicina para conmemorar el bicentenario del nacimiento del médico inglés John Snow, se llevó a cabo el foro: “Desarrollos Metodológicos en Epidemiología”. Médico británico es conocido como el padre de la epidemiología, al vincular en 1854 el agua contaminada procedente de una bomba de agua, como agente vector del brote de cólera que ocurrió en Londres, en Broad Street. Su contribución a la epidemiología matemática fue también destacada, por su aporte en el cálculo de tasas de infección y estimación de la probabilidad de infección. Se hizo un recuento de las enfermedades infecciosas en la historia y los aportes de los modelos epidemiológicos. También presentó ingeniosos instrumentos y procedimientos quirúrgicos en la Sociedad Médica de Westminster, descritos en la Gaceta Médica, una revista londinense. Fue pionero en anestesiología por sus estudios con el cloroformo, y diseñó un vaporizador para administrarlo adecuadamente a miles de pacientes, incluyendo anestesia obstétrica en dos partos de la Reina Victoria.

JOHN SNOW: METHODOLOGICAL DEVELOPMENT OF EPIDEMIOLOGYABSTRACTA workshop on the legacy of English physician John Snow took place at the National Academy of Medicine, on occasion of his bicentennial. This British doctor is remembered as the father of epidemiology, since he was able to link contaminated water coming out of a pump in Broad Street (London) and the cholera outbreak that happened in the same place. He did not know the bacteria, but he realized that an infectious agent present in the water they were using was the cause of disease spread, causing many casualties in 1854. He gave hints for recent developments in molecular epidemiology. His contribution to mathematical epidemiology included infections´ rate calculation, making estimates on probability of disease. A summary of burden of infectious diseases throughout history and contributions to epidemiology models was made. Furthermore, Snow cleverly designed devices and surgical procedures in meetings of the Westminster Medical Society, some of the published in Medical Gazette, a London journal. He did pioneering studies on chloroform, designing an evaporator to deliver adequate doses, giving the drug to several thousand patients, including obstetric anesthesia for Queen Victoria in two instances.
Key words: John Snow, epidemiology, mathematical epidemiology, rate of infections, cholera, contaminated water, chloroform, anesthesia
