Header Banner: Snow was a British physician who is considered one of the founders of epidemiology for his work identifying the source of a cholera outbreak in 1854. After careful investigation, including plotting cases of cholera on a map of the area, Snow was able to identify a water pump in Broad (now Broadwick) Street as the source of the disease. He had the handle of the pump removed, and cases of cholera immediately began to diminish. However, Snow’s ‘germ’ theory of disease was not widely accepted until the 1860s. The DarkDrug Logo shows the small pox virus, eradicated from the wild through effective vaccination after Edward Jenner’s discovery in 1798. The last naturally occurring case was diagnosed in October 1977 and the World Health Organization certified the global eradication of the disease in 1980.
