Historical reported cases and estimates

The following is provided for archival and historical purposes only. As noted in “Adjustments to Reported Cases” (page 16) of the DVH Surveillance Summary 2011, using new methodology for 2011 data, these estimates have wide confidence intervals and cannot be compared directly with estimates from previous years that were obtained using different calculations.
