Applying Network Theory to Epidemics: Control Measures for Mycoplasma pneumoniae Outbreaks
Figure 4

Figure 4. . Epidemic thresholds. Each line assumes a different value for μc(the average number of wards per caregiver), and graphs the combination of τc and τw(transmission parameters) above which the population crosses the epidemic threshold. From top to bottom, the lines represent μc= 1, μc= 2, μc= 3, μc= 4, and μc= 5 .
1We calculate these rates by averaging the fraction of infected patients per ward across the 15 wards and compute the error by taking the standard deviation of these fractions, divided by the square root of the sample size.
