Just be sure to understand that fitting data like you have plotted there is only good for interpolation, not extrapolation. So this doesn’t infer anything about where we will be next week.
Extrapolation is the mistake made by so called climate change experts that show the hockey stick, exponential growth based on an interpolation fit. The higher order the fit, yours are second order, the more rapid the extrapolation will run away.
In this case, the data is very good for extrapolation. Disease outbreaks always follow a classical growth curve. Until the outbreak starts to pass, we will continue to see this kind of growth.
The problem with the “climate change” modeling is that it is based on incorrect assumptions. The rate of spread of disease is a topic that is very well studied.
