2011 Viral Hepatitis Data

This report provides an analysis of the viral hepatitis cases reported in North Dakota for the year 2011. It highlights the limitations of the data, including under-reporting of infections, reliance on positive lab results, and CDC case definitions. It distinguishes between acute and chronic infections, but does not separate resolved from active cases. The report includes demographics, gender, age group, and racial data for hepatitis C and B cases. Additionally, it discusses the baseline year for data collection and the impact of the new electronic reporting system (DREAMS).
