Take a look at that same CDC site now (8/16/20) and notice that it's no longer diminishing for dates more than 2 weeks ago. The death rate as shown always appears to diminish for the last 2 weeks of the chart because of the delay in reporting data. Since 6/20, we can see that the death rate is going up again. Typical flu deaths were 30k in a year. This will soon be 200k in less than a year.
Interesting.. can you provide a link to some information on the 15 contacts being counted along with positive actual tests? I'd like to learn more about that.
Here's another useful charting page that has a number of different data-viewing options. http://covid19chart.org/#/?select=CA%3BFL%3BTX&start=3%2F1%2F20&stat=7day&norm=pop&include=San%20Diego,%20CA%3BTX&series=deaths&scale=linear
