Weekly number of new rotavirus cases among the three aggregated age groups of 0–4, 5–59, and 60–99 years of age in Germany between 2001–2008. The values we used for scaling up are the median estimates of the under-reporting parameter from the averaged posterior distribution inferred in Weidemann and others (2013), namely 4.3% in the former western federal states (WFS) and 19.0% in the former eastern federal states (EFS) between 2001 and 2004 and 6.3% in WFS and 24.1% in EFS from 2005 onward. This sudden increase in reporting behavior is due to a nationwide change in the reimbursement of hospitalized rotavirus cases from January 2005.
