Just for a bit of clarification, Pneumonia is simply a symptom of a particular type of infection, of which there are a variety of causes (bacteria, viri, Fungi etc) See:

This is further clarified here:

So, infections can cause Pneumonia, but Pneumonia is not a disease in itself; it is a symptom.
The serious and critical rate is currently tracking at 11%:

The growth rate of infections is exponential:

Beware of the last value on each of these graphs, they rely on areas reporting their figures for the day, and due to time-zones this means data updates are staggered. A flat figure does not mean the virus has suddenly stopped.
In terms of cases with an outcome (cured or death) the death rate is tracking at 6%. This is higher because not all mild cases are diagnosed, and is expected to be closer to 2%.
The spread of Covid19 is quite high, with an R0 tracking from 2.4 and up (some say 3, others 6.7, it's simply bad, and much higher than the standard Flu.)
For a comparison to the Flu, see this:
