Statistics and Epidemiology supports WRAIR's efforts to understand and solve the medical threats to Soldiers through timely, relevant, and high-quality statistical support to a diverse array of research endeavors including infectious diseases, chronic diseases, behavioral health concerns, and battlefield and non-battle injuries. These techniques are used to identify emerging and existing threats to Soldier readiness and lethality as well as evaluate the impact and efficacy of developed products.

Statistics and Epidemiology aims to continue the work of Dr. John Snow (1813-1858), a legendary figure in the history of public health, epidemiology and anesthesiology. Considered one of the founders of modern epidemiology, he traced the source of the 1854 source of a cholera outbreak to a water pump in Broad (now Broadwick) Street in the SoHo district of London, England by applying statistical mapping methods to what might have been thought of as 'anecdotal' evidence from groups of people near the outbreak. His discovery that cholera was water borne revolutionized the study and investigation of disease transmission.
