Looking at the infected population chart as published on C|Net, I have to
say that the dramatic increase looks exactly like the classical "knee" in a
exponential growth curve. In fact, the entire curve looks like a standard
infection "population vs. time" graph, with the upper end fall-off due to
the saturation of the available uninfected population. No nefarious
modifications are needed here to explain the sudden surge.

For entertainment value, try creating a chart (I used Excel), plotting
y=x^9. Then look at the curve. The knee starts around x=20 or 21, and the
value takes off from there. No modifications needed.
