Top 30 Bacterial Serotypes from U.S. Enteric Disease Surveillance

Quarterly data from 2024 onward tracks the 30 most common serotypes for pathogens like Salmonella and E. coli, including isolate counts and trend comparisons. The dataset is produced by the CDC's SEDRIC system and visualized via the BEAM Dashboard. It supports the monitoring of foodborne and animal-contact illness trends.

Use Cases

• Analyze temporal trends in pathogen prevalence by grouping data by Year and Quarter.
• Identify serotypes with significant increases using the % Change and Past two years average columns.
• Compare the current Number of isolates for a Serotype/Species/Subgroup against its historical baseline.
• Monitor specific Pathogen groups (e.g., Salmonella, Escherichia) for emerging public health concerns.

Strengths

• Data is updated quarterly, providing timely surveillance information.
• Includes calculated metrics like % Change and Past two years average for trend analysis.
• Focuses on the top 30 serotypes, highlighting the most significant public health threats.

Limitations

• Unknown total row count and sample size limit detailed statistical analysis.
• Geographic coverage is not specified, potentially limiting generalizability.
• Data is limited to the top 30 serotypes, excluding less common but potentially important variants.
