Again, the timing of disease is accounted for to some degree in all investigations - meaning that a study investigating the worldwide incidence of Rinderpest in 1900 would give very different results from that in 2010. However, some studies may further investigate and quantify the temporal pattern of disease. One example of this is outbreak investigation, where the number of cases of disease within a population over time may be plotted in the form of an 'epidemic curve'. This can provide useful information regarding trends of disease, and may advise upon the effectiveness of any control measures instigated.<br>
