COVID-19 Cases Confirmed Summary
In the daily COVID-19 cases confirmed table, there is a surprising finding. The number of new cases in 03Jun 2020 and 24July 2021 is Negative. This situation may be caused by an error in the previous test result, or other reasons. The data is limited, so that no in-depth analysis will be done in this blog.
COVID-19 Deaths Summary
In the COVID-19 Deaths table, there is the same finding as well. The number of new death in the 24July 2020 is negative. This may be a duplicate record when the new death cases were counted previously, or the cause of death was not COVID-19.
COVID-19 Cases Confirmed and Death Summary
In order to show the trend of the COVID-19 Cases Confirmed and Death in China from 22Jan 2020 to 30Aug 2021, we do the plot in this blog.
