NNDSS - TABLE 1O. Hansen's disease to Hantavirus pulmonary syndrome

United States provisional weekly case counts for Hansen's disease and hantavirus infections, reported through the National Notifiable Diseases Surveillance System (NNDSS) in 2022. The data is collated by the CDC from reports submitted by 50 states, New York City, the District of Columbia, and U.S. territories. Case counts are subject to revision and delayed reporting, as noted in the accompanying guide.

Use Cases

• Tracking weekly case trends for Hansen's Disease and Hantavirus pulmonary syndrome using the Current week, MMWR Week, and MMWR Year columns.
• Comparing current year-to-date totals to previous periods using the Cum 2022† and Cum 2021† columns for each disease.
• Identifying reporting jurisdictions with unusually high activity by analyzing the Previous 52 weeks Max† and Current week columns alongside the Reporting Area and States columns.
• Mapping case reports by jurisdiction using the geocode, Reporting Area, and case count columns to visualize geographic distribution.

Strengths

• Data originates from the authoritative National Notifiable Diseases Surveillance System (NNDSS) managed by the CDC.
• Includes multiple temporal aggregations: current week, year-to-date cumulative (2021 and 2022), and previous 52-week maximum for trend analysis.
• Contains geographic identifiers like Reporting Area, States, Counties, and geocode for spatial analysis.

Limitations

• Case counts for 2021 and 2022 are provisional and subject to change due to delayed reporting and revisions.
• Row count and total dataset size are unknown, which may limit suitability assessment for large-scale analysis.
• Some data may be marked as unavailable (U), not reportable (N), or not calculated (NC), requiring careful filtering.
