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.

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 charts below show the progress based on number of cases/100,000 population.

As at 23rd November 2021, Australia has had ~33,900 local cases in the last 28 days and exceeds the size of largest previous outbreak. The number cases per 100,000 people in UK and US are rising slowly while Australia's are falling. Australia has >84% (12years+) fully vaccinated and >90% first dose. NSW has almost 91% (12years+) fully vaccinated and >93% first dose.

As can be seen from the Australia/New Zealand chart lower down, New Zealand managed to initially get on top of its Delta variant outbreak but the case are now rising, while bad decisions by the NSW and now the VIC government has let it get out of control in Australia but the outbreak is now receding. As a side note, Tasmania (an island state to the south of the Australian mainland) as not had a local COVID case in the last 17 months and has recently managed to capture an infected escapee from local quarantine who threatened to spark an outbreak.

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

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.
