I haven't posted US numbers graphs in a little while. I've got four to share today. These are US numbers as of yesterday.
Logarithmic Growth of COVID-19
In a logarithmic graph, a straight line shows exponential growth. The red line shows that we saw exponential growth for a pretty long while. As you can see, over the past month or so, this graph has been flattening considerably. While our daily growth numbers have remained stable over the past few days (as a future graph will show), exponential growth is simply not happening on a national scale any longer. This can, of course, change with a hypothetical second wave, but for now it is encouraging.
Percent Growth
This graph illustrates just how small the growth is becoming on the whole. While new sick people are certainly always a problem, as a representation of growth we are narrowing into a range of 4%. Growth at this level has a doubling time of 18 days. The worst we saw in the numbers was a doubling time approaching once every 2 days. Obviously this is a huge benefit. The red line is a 5 day rolling average.
Actual Daily Growth
The actual daily growth has simply stopped growing. Let me show you this same graph zoomed in.
By only looking at the past 14 days, we can see that our daily growth is actually just barely trending down (green line is a linear trend line of this time period). Again, 30,000 new sick people a day is certainly tragic, but seeing a trend downwards certainly offers a glimmer of hope to us all.
Conclusion
Yes some of this data is limited by testing, but this is less of a problem compared to even a short time ago. I've seen several counties in my state offering free testing to anyone that is willing to come through a drive through whether or not you have shown symptoms. On top of that, deaths are beginning to trend downwards in some of the states that states that were hardest hit by this virus. New York has gotten a good enough hold of their situation that they have begun offering their resources to other states. While we will never know the true number of people that were affected by this illness, we can have confidence that things are beginning to look a little better. Testing is becoming far more available while deaths are leveling off and even dropping.
