NNDSS Table II: U.S. Acute Viral Hepatitis Surveillance Data, 2013-2014

Provisional 2014 data on acute viral hepatitis cases in the United States, reported weekly to the National Notifiable Diseases Surveillance System (NNDSS). The dataset includes case counts for hepatitis A, B, and C, broken down by reporting area and featuring current week, year-to-date cumulative, and 52-week summary statistics. Data is collated by the CDC from reports submitted by 50 states, New York City, the District of Columbia, and U.S. territories.

Use Cases

• Analyze weekly case trends for hepatitis A, B, and C by Reporting Area using the 'Current week' columns.
• Compare annual disease burden across states for 2013 and 2014 using the 'Cum 2013' and 'Cum 2014' columns.
• Assess the variability of weekly reports over a year using the 'Previous 52 weeks Med' and 'Previous 52 weeks Max' columns for each hepatitis type.
• Map state-level hepatitis incidence by joining on the 'Location 1 (state)' column with geographic data.

Strengths

• Includes data for three major types of acute viral hepatitis (A, B, C) across multiple temporal dimensions (current week, year-to-date, 52-week summaries).
• Provides geographic granularity down to the state level via the 'Reporting Area' and 'Location 1 (state)' columns.
• Data is sourced from the authoritative CDC National Notifiable Diseases Surveillance System (NNDSS).

Limitations

• Data is provisional and subject to revision, as noted in the description.
• Last updated 2015-08-27 22:44:43; freshness should be verified.
• Row count is unknown, which may limit suitability assessment.
