Delaware RSV Wastewater Viral Activity Levels By Week

Weekly data on Respiratory Syncytial Virus (RSV) levels in wastewater, provided by the Centers for Disease Control and Prevention (CDC) via data.delaware.gov. It includes viral activity levels categorized from 'Very Low' to 'Very High' based on defined thresholds. The dataset supports public health tracking and was last updated in April 2026.

Use Cases

• Forecast future RSV activity_level using historical Week_Ending_Date and StateorTerritory_WVAL time series.
• Classify WVAL_Category (e.g., 'High', 'Moderate') from features like National_WVAL and Regional_WVAL.
• Analyze geographic disparities in RSV spread by comparing StateorTerritory_WVAL with National_WVAL.
• Assess data Coverage completeness over time to identify reporting gaps in the Data_Collection_Period.

Strengths

• Includes standardized activity_level categories with defined numerical thresholds (e.g., >8 to 11 = 'High').
• Provides multiple spatial aggregation levels via StateorTerritory_WVAL, Regional_WVAL, and National_WVAL columns.
• Data collection methodology is documented and provided by the CDC.

Limitations

• Sample size and row count are unknown, limiting assessment of statistical power.
• Geographic representation may be biased as noted in the description, with some areas having higher density of sampling sites.
• Specific license terms and data update frequency are not provided.
