Due to the relatively long latent period of hepatitis A, epidemic curves generally show an irregular rate of increase in case reports, often with a low number of case notifications early in the outbreak period (e.g. [ 19, 20]), which was consistent with the simulation model output.
In 1997, for instance, Taiwan was struck by a epidemic that ended up costing it $5 billion in lost revenues, containment efforts and compensatory payments to farmers whose livestock had to be destroyed.
These ultrasound findings were helpful in distinguishing bacterial versus viral pneumonia during the H1N1 influenza A epidemic in 2009 with high inter-observer agreement [196].

Both parametric and non-parametric subtype B demographic curves looked approximately linear during the first decade of the epidemic, and experienced a sharper increase only within the next fifteen years during the same time-frame of the introduction and exponential growth of subtype A epidemic (Figure 3).
