Powassan Virus in Adult Deer Ticks Across New York State, 2009 Onward

Adult deer ticks collected across New York State are tested in pools for Powassan virus, with results providing localized infection rates from October to December each year. The dataset includes 20 columns such as Pools Tested, Pools Positive, Minimum Infection Rate, and County Location. Data is provided by health.data.ny.gov and was last updated in May 2025.

Use Cases

• Modeling Minimum Infection Rate based on Year, County, and Tick Population Density using regression on 20 available columns.
• Mapping disease risk using County Location, Counties, and NYS Senate Districts for geospatial analysis.
• Analyzing annual trends in Pools Positive and Total Ticks Collected versus Total Sites Visited for surveillance program assessment.

Strengths

• Data collection spans from 2009 onward, providing a multi-year time series.
• Includes 20 columns with specific metrics like Minimum Infection Rate and geospatial identifiers like County Location and Zip Codes.
• Last updated on 2025-05-02, indicating recent maintenance.

Limitations

• Row count is unknown, which may limit suitability assessment.
• The description explicitly warns data should not be used to broadly predict county-level disease risk due to local variation.
