1998-2024 case counts for invasive pneumococcal disease (IPD) from the CDC's Active Bacterial Core surveillance (ABCs). The data includes counts by serotype, age group, and surveillance site, used to measure the impact of pneumococcal vaccine use in the United States. Data is provided by data.cdc.gov and was last updated in May 2026.
Use Cases
- Analyze serotype trends over time using the Year and IPD Serotype columns.
- Compare disease incidence across different age demographics using the Age Group (years) and Frequency Count columns.
- Assess geographic variation in serotype distribution using the Site column.
- Evaluate vaccine impact by tracking changes in vaccine-type serotype frequencies across the Year and Age Group (years) columns.
Strengths
- Data covers a 27-year time span from 1998 to 2024.
- Case counts are stratified by six distinct age groups and multiple surveillance sites.
- Data is sourced from the CDC's Active Bacterial Core surveillance (ABCs), a laboratory- and population-based system.
Limitations
- Row count and dataset size are unknown, which may limit suitability assessment.
- The description notes that surveillance methods and areas have changed over time, so trends should be interpreted with caution.
- License and author information are not specified in the provided metadata.
