These charts will be updated on an approximately weekly basis. Dates are in year/month/day format. See here for How to read these charts.

Most of the charts here are total cases charted on a log/log scale. You would expect countries with larger populations to have (on average) more cases.
So to get a better feel for relative response of a few countries, the first 2 charts below show the progress based on number of cases/10000 population, for the US, UK and Australia.

As at 24th Nov 2020, Australia has had a (very) few more cases, the UK's lock down is starting to show results and US continues its uncontrolled increase in cases.

This is the same chart as above but on a log/log scale

Another set of plots on a log/log scale.
Here the plots are of total case numbers where the US is much higher than the UK and France.

How to read these charts

There is a dot per day with the last dot being the chart's date. These charts show the pandemic's progression in more detail than alternative charts which loose detail as the number of cases increases.

The charts plot the number of cases in the previous 7 days against the number of case in the last 35 days on log scales. That is the approximate new cases versus the currently active infective cases. Cases that are more then 35 days old have resolved. That is the people have either recovered, or died, and are not infective any more. (Previously the charts were 5 days / 30 days, but using weekly multiples (7/35) gives smoother charts).

Countries with plots moving up are getting more new cases. Countries with plot moving right have more active infective cases. Plots going down or to the left are countries that are getting better.

There are two diagonal lines on the chart. Countries with plots near the upper lines are experiencing rapidly increasing numbers of cases. Countries with plots on the lower line have stabilized the number of new cases. Countries with plots below the lower line are reducing their cases.

If the country name has a date associated with it. That date is the start of its lock down and is shown on the charts with a small cross.

All these charts are in-accurate to the extent that the countries are not conducting wide spread testing to determine the true extent of the virus in asymptomatic carriers who can infect other people.
