Covid-19 tracker for busy people :) - tracks the trend of increasing/decreasing in new cases in the two most recent periods of N days.
We consider the ratio: (new cases in the last N days) / (new cases in the second last N-day-period)
For example: N = 7 => (this week's new cases)/ (last week's new cases).

The ratio > 1.0: virus not slowing down, new cases grow over time (countries above the red line in the chart).
The ratio < 1.0: the number of newly detected cases is decreasing (countries below the red line)

Choose N:

Countries with > 500k confirmed cases in total, data automatically refreshed daily from Johns Hopkins CSSE : Reference

For countries with less than 500k confirmed cases: Tracker for countries < 500k cases
