node

After mapping deaths in the Soho cholera outbreak against the pumps that served the households, John Snow persuades the Board of Guardians of St James parish to remove the handle from the Broad Street pump. The outbreak was already in decline, so the action did not end it; its importance is as the first use of spatial epidemiology to identify a source.
