[One hundred years later, recalling how BMJ and JAMA reported the 1918-1919 influenza pandemic].

The influenza pandemic that ravaged the planet in 1918-1919 is, undoubtedly, the most virulent and lethal infectious disease that the human species has ever overcome. This essay was to evaluate the medical interpretation of this phenomenon and the response given by doctors in terms of diagnostic and therapeutic technology based on the data published in the medical literature of two of the most important journals of the time, BMJ (The British Medical Journal) and JAMA (The Journal of the American Medical Association). It was found that the arsenal of knowledge, diagnosis and therapeutics of the time offered very few tools to address clinical management and curb contagion and mortality.
