A useful website, pulled together by the epidemiologist Professor Marcel Salanthe, that provides simple explanations of virus spread and measures that are effective in stopping this, together with a tool to explore modelling different results from different actions. https://ncase.me/covid-19/

"The Last Few Months (epidemiology 101, SEIR model, R & R0)"

To beat COVID-19 in a way that also protects our mental & financial health, we need optimism to create plans, and pessimism to create backup plans. As Gladys Bronwyn Stern once said, “The optimist invents the airplane and the pessimist the parachute.”
