Eh? "Epidemiology is the science that studies the patterns, causes, and effects of health and disease conditions in defined populations" :?
nowadays the term exponential function is almost exclusively used as a shortcut for the natural exponential function ex, where e is Euler's number, a number (approximately 2.718281828) such that the function ex is its own derivative.[1][2] The exponential function is used to model a relationship in which a constant change in the independent variable gives the same proportional change (i.e. percentage increase or decrease) in the dependent variable. The function is often written as exp(x), especially when it is impractical to write the independent variable as a superscript. The exponential function is widely used in physics, chemistry, engineering, mathematical biology, economics and mathematics.
Exponential function
Representation e^x \,
Inverse \ln x \,
Derivative e^x \,
Indefinite Integral e^x + C \,
The graph of y = ex is upward-sloping, and increases faster as x increases. The graph always lies above the x-axis but can get arbitrarily close to it for negative x; thus, the x-axis is a horizontal asymptote. The slope of the tangent to the graph at each point is equal to its y coordinate at that point. The inverse function is the natural logarithm ln(x); because of this, some old texts[3] refer to the exponential function as the antilogarithm.
In general, the variable x can be any real or complex number or even an entirely different kind of mathematical object; see the formal definition below.

Problem is, exponential decay is just as possible as exponential growth unless we get our collective finger out! Analysis of linear rate (above) has shown it will take 8 years to achieve the target.
I've just posted the link to the petition on LinkedIn, everybody do the same with their social networking sites (Facebook etc, whatever).

Exactly - epidemiologists are likely in a frenzy fretting about the exponential growth of Ebola even as we type... Here's hoping this petition has the government as worried
By the seaside...
I think you'll find that epidemiology also covers the rate of spread of infectious disease - such as the current ebola outbreak. Some quite complex maths can be involved as there are a lot of factors to account for, each of which can vary over a range causing growth estimates to lose precision as they are projected further ahead
I agree, it can be fascinating - I'm not much of a mathematician anymore (not since A level days), but I can appreciate the intellect behind such things. Now biomechanics and orthopaedic engineering on the other hand, they are elements of basic science that I really do enjoy.
