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

United States provisional weekly case counts for nationally notifiable diseases from Hansen's disease to hantavirus pulmonary syndrome. The data is published by the National Notifiable Diseases Surveillance System (NNDSS) and includes counts for 2019 and 2020, with year-to-date cumulative totals and previous 52-week maximums. Cases are reported by U.S. states, territories, and include a category for non-U.S. residents.

Use Cases

• Track weekly disease incidence trends using the 'Current week' and 'MMWR Week' columns for specific conditions like 'Hansen's Disease'.
• Analyze year-over-year changes in disease burden by comparing 'Cum 2019†' and 'Cum 2020†' columns for each disease.
• Identify reporting anomalies or data quality flags by examining the 'flag' columns associated with case counts.
• Map disease reports by jurisdiction using the 'Reporting Area' and potentially georeferenced location columns.

Strengths

• Data is sourced from the authoritative National Notifiable Diseases Surveillance System (NNDSS).
• Includes multiple temporal aggregations: current week, year-to-date cumulative, and previous 52-week maximum counts.
• Provides data quality flags (e.g., 'U' for unavailable, '-' for no cases) to aid in interpretation.

Limitations

• Case counts for 2019 and 2020 are provisional and subject to change as follow-up information becomes available.
• Row count and total data volume are unknown, which may limit suitability assessment for large-scale analysis.
• Country of usual residence, used to assign the 'Non-U.S. Residents' category, is not reported by all jurisdictions.
