The Good and the Bad on New COVID Cases

Bad new: U.S. had a record number of new cases yesterday. Good news: It’s because testing is improving. Conclusion: If governors stick to their rules, still a few weeks of stay at home.

California (my home state) is also near record high new cases.

One criteria is testing, which we still need more of. We also don’t have the capacity to test and trace. We don’t have a 14 day decline of cases. In fact, in theory, we now need 13 days of declining positives to meet the reopening criteria nationwide.

Regardless of what you think about the ‘rules,’ we don’t set them – Elected officials do. My predictions are based on their laid out criteria. I still see an opening of May 15th or later for the major population areas of the U.S.

U.S. Falling Behind Italy Recovery

For weeks, I’ve expected the U.S. to largely follow the path of Italy – and so far it has. Unfortunately, the last few days, U.S. cases have not been declining as fast as Italy.

Italy (+ 14 days) vs. US Covid-19 Cases

As seen in the graph, the cases matched well until about April 11th when the US has started staying much higher than Italy.

If we calculate a 5 day average of cases to remove testing variability, we can see the US is now close to 80% of peak cases while Italy was only 60% at this time.

It seems rather – and probably naturally – that we are now closer on the EU path. Like the EU, we have different ‘countries’ (i.e. states) with different restrictions. This is expanding our plateau period

EU (+9 Days) vs. US Covid-19 Cases

Note, however, that both Italy and the EU graphs suggest about 60% of peak cases in the US on May 1st. Thus, it is possible we end up converging still.

A good reason for the increase in cases yesterday is better testing – so that is a good thing.
