In [16] the authors report initial findings on the current H1N1 Influenza pandemic, including results from data collected on a localized outbreak in La Gloria, Mexico. Data for this analysis was obtained by surveying 1575 Figure 1 Simulation results for the estimate of the reproductive number. The first boxplot (All) in each frame shows results when all the data is used. Each subsequent couplet of boxplots first shows the estimates when missingness is correctly accounted for and second, when missingness is ignored when estimating. The numbers on the × axis denote the missingness scheme applied to the data (see text of manuscript for a detailed description). For example the first couplet corresponds to constant missingness of 0.05 with the left boxplot giving the results when missingness is accounted for and the right one for estimates when missingness is ignored. The horizontal line indicates the true value of the parameter. villagers out of 2243 villagers recorded in 2005 [17] . Of those surveyed, 615 cases were reported. It was later discovered that some of these reported cases were from seasonal flu. Figure 3 shows the observed data.
