Influenza A Wastewater Surveillance Metrics from US Locations

Weekly updated time history of Influenza A wastewater sample data and calculated metrics from US sampling locations. The dataset is compiled by the CDC's National Wastewater Surveillance System (NWSS) from state health departments, a CDC contract with Verily, and the WastewaterSCAN partnership. Data includes sample collection dates, PCR target concentrations, and population served metrics.

Use Cases

• Model influenza A trends over time using `sample_collect_date` and `pcr_target_avg_conc_lin`.
• Analyze geographic disparities in virus concentration across `state_territory` and `county_fips`.
• Correlate wastewater signals with population density using `population_served` and `counties_served`.
• Assess data quality and methodology differences by comparing results from different `source` designations.
• Track detection rates and viral load via the `pcr_target_detect` and `lod_sewage` columns.

Strengths

• Weekly update frequency ensures current surveillance data.
• Includes data from multiple authoritative sources (CDC, state health departments, WastewaterSCAN).
• Contains over 30 columns detailing sample metrics, location, and laboratory methods.

Limitations

• Exact row count and historical time range are not specified.
• Limited to Influenza A, excluding other respiratory viruses.
• Data completeness may vary by reporting jurisdiction and `source`.
