Detailed explanation-1: -Snow was skeptical of the predominant Miasma Theory, and theorized that the cause of cholera was due to contaminated water as the main form of transmission. In 1854, a cholera epidemic broke out, affecting resident families of tailors and clerks from the shops of nearby Regent Street.

Detailed explanation-2: -In miasma theory, it was believed that diseases were caused by the presence in the air of a miasma, a poisonous vapour in which were suspended particles of decaying matter that was characterised by its foul smell. The theory originated in the Middle Ages and endured for several centuries.

Detailed explanation-3: -A person can get cholera by drinking water or eating food contaminated with cholera bacteria. In an epidemic, the source of the contamination is usually the feces of an infected person that contaminates water or food. The disease can spread rapidly in areas with inadequate treatment of sewage and drinking water.

Detailed explanation-4: -Snow believed sewage dumped into the river or into cesspools near town wells could contaminate the water supply, leading to a rapid spread of disease. In August of 1854 Soho, a suburb of London, was hit hard by a terrible outbreak of cholera.

Detailed explanation-5: -Snow recorded cholera attacks in this area, alongside information about the water supply to the houses affected. He showed that the Southwark and Vauxhall Waterworks Company was taking water from sewage-polluted sections of the Thames and delivering the water to homes, leading to an increased incidence of cholera.
