Delaware COVID-19 Wastewater Viral Activity Levels with CDC Methodology

The Delaware COVID-19 Wastewater Viral Activity Levels dataset is provided for public use by the Centers for Disease Control (CDC). It contains weekly viral activity levels for Delaware, categorized from 'Very Low' to 'Very High', based on wastewater monitoring. The data includes columns for Data_Collection_Period, National_WVAL, Regional_WVAL, Week_Ending_Date, StateOrTerritory, Coverage, StateOrTerritory_WVAL, and WVAL_Category.

Use Cases

• Track state-level viral trends over time using StateOrTerritory_WVAL and Week_Ending_Date.
• Compare state activity against regional and national baselines using Regional_WVAL and National_WVAL.
• Classify weekly public health risk levels using WVAL_Category and Data_Collection_Period.
• Assess geographic data coverage for a state or territory using the Coverage column.

Strengths

• Data is provided by the CDC, an authoritative public health institution.
• Includes multiple granularity levels for viral activity: state, regional, and national.
• WVAL_Category provides an interpretable risk scale from 'Very Low' to 'Very High'.

Limitations

• Row count is unknown, which may limit suitability assessment.
• The median wastewater viral activity level may not represent every community, as noted in the description.
