New confirmed deaths of COVID-19 in the past week, by number of days since 10 new deaths in one week

Financial Times runs a graph for the new confirmed cases of COVID-19 in the past week, by the number of days since 200 new cases in one week. Below is the figure I reproduced based on data from a different source as of April 1st, 2020.

I have plotted a similar chart, with new deaths instead of new cases against the onset of the COVID-19 epidemic in several countries since we deem deaths more reliable than cases. It shows a similar pattern as the plot for cases. Amazingly, South Korea managed well to suppress a surge in deaths despite the rapid spread of the disease in the early phase. China is seeing a resurgence of infection but that has not resulted in a second hump of the curve for deaths.

The number of cases depends heavily on various factors such as access to health care and diagnostic tests, medical practice, and patients' behavior and complicates the interpretation of data by country. In contrast, the number of deaths is much more robust than that of cases since, in whichever developed countries, patients in severe conditions likely go through tests repeatedly not only for their treatment but to protect medical staff, leaving few deaths from COVID-19 undiagnosed.
