ABOUT THE JOHN SNOW MEMORANDUM

John Snow is considered one of the founders of modern epidemiology. He developed the water theory of transmission of cholera. In 1854, he famously persuaded authorities to remove the handle of a water pump to try to curtail transmission of cholera during an outbreak in London. He devoted much of his life to improving public health.

The John Snow Memorandum is the work of a group of international researchers with expertise spanning public health, epidemiology, medicine, paediatrics, sociology, virology, infectious disease, health systems, psychology, psychiatry, health policy, and mathematical modelling. We felt moved to deliver a clear and simple message about how best to manage the COVID-19 pandemic.

The John Snow Memorandum is a grass roots initiative that has not received any outside funding. The costs of this website and the time spent developing the memorandum were donated by signatories who are motivated by a desire to protect public health. For a full declaration of authors' interests, please see the original publication in The Lancet.

This is a collaborative, inclusive initiative and we invite colleagues from around the world to signal their support for the memorandum by becoming signatories.
