I scratched numbers from the WHO situation reports, and created a shiny app to show the time-series movement of the newly confirmed cases by each area, as I would like to know whether coronavirus is being contained in Japan, or other areas.
The sites, like Coronavirus Situation Dashboard by WHO and Coronavirus Update by worldometer, utilize the WHO situation report numbers, but so far I could not find any API or csv files I can use. Scratching numbers from pdf files is a dirty work. I would like to update frequently, but I am not sure.
