History of the discovery of the mode of transmission of yellow fever virus.

This essay documents and examines the historical circumstances and events surrounding the discovery of the mode of transmission of yellow fever virus in Cuba. Close scrutiny of the articles published by Walter Reed and his colleagues in 1900, 1901 and 1902 reveals their limitations as historic documents. Fortunately, other sources of information from that period survive in letters and documents written by individuals involved in the quest for the mode of transmission. Examination and comparison of those sources of information unveiled a fascinating story which reveals that misunderstandings engendered by published articles accorded merit where it was not fully due.

Carlos J Finlay (1833-1915) Su impronta en el Canal de Panamá en el centenario de su muerte / The mark he left in the Panama Canal in the centenary of his death

El médico cubano Carlos Finlay dedicó su vida al estudio de la fiebre amarilla y descubrió que su agente transmisor era el mosquito Aedes aegypti. Si bien durante veinte años su descubrimiento no fue tenido en cuenta por el mundo académico de la época, su teoría fue confirmada y permitió el saneamiento de la isla de Cuba, que fue liberada de nuevas epidemias. A fines del siglo XIX, la fiebre amarilla fue una de las causas del fracaso de la compañía francesa que intentó construir sin éxito un canal interoceánico en Panamá. En 1904, los estadounidenses, teniendo en cuenta estos antecedentes y llevando a la práctica lo aprendido con Finlay en el saneamiento de Cuba, lograron con éxito la construcción del Canal de Panamá.

Carlos J Finlay was a Cuban phisician that devoted his life to the study of yellow fever and discovered that the Aedes aegypti mosquito was its transmitting agent. Even though his discovery was not taken into account by the academic world of the time for twenty years, his theory was confirmed and allowed the cleaning of Cuba, freeing the island from new epidemics. At the end of the 19th century, a French company tried and failed to build an inter-oceanic canal in Panama, and one of the reasons of the failure was yellow fever. In 1904, Americans managed successfully to build the Panama Canal considering this background and putting into practice Finlay’s lessons regarding the sanity in Cuba.
