1) The forecast appears to be "200 new cases per month" (i.e. Month 1 is 200 cases, Month 3 is 600 cases (3200) and Month 4 is 1200 cases (6200)). This is far too simplistic, and should probably follow an exponential/logistic curve if r>1.
2) The graph has simple stats failures like plotting a line between a bar chart.
Doesn't give me too much hope for the other 15 slides...
(The above isn't to say that it isn't a scary situation - clearly this is an awful situation which needs a huge amount of support. But the apparent quality of analysis does worry me that decision makers might not be working on great information)
