The time-series of new Covid-19 cases detected every day might suggest that a peak has been passed.
However, it is very difficult on the exponential growth section to be able to tell when the curve begins to flatten off. The growth of Covid-19 cases is better looked at, I think, in terms of new cases against the cumulative number of cases rather than just the traditional time-series. A caveat is that the number of positive cases depends upon the testing strategy. Nevertheless plotting the daily new cases against the cumulative cases on logarithmic scales is a better guide as to whether exponential growth is still occurring.
There are indications that the growth may just be getting off the exponential growth rate but it is not clear yet.
In any event I prefer this plot to the simple time-series.
Sweden’s voluntary lock-down may be able to flatten the curve
