Infected Blacklegged Tick Nymph Risk in New York, 2008 Onward

Over 10,000 individuals in New York are impacted by tick-borne diseases yearly. The New York State Department of Health (NYSDOH) monitors pathogens through active tick surveillance, which began statewide in 2008. This dataset records nymph tick density and infection prevalence across NY regions from May to September.

Use Cases

• Model regional tick-borne disease risk using Tick RIsk Score and Prevalence of infected ticks.
• Analyze spatial patterns of nymph density using NY Region and The_geom columns.
• Correlate surveillance effort with findings using Total Sites Visited and Total Tested.
• Categorize risk levels or site types using the Category column alongside Site Total.

Strengths

• Statewide active surveillance data collected since 2008 by the New York State Department of Health.
• Includes geospatial data (The_geom) for mapping and regional (NY Region) analysis.
• Provides multiple calculated metrics like Average Nymph Density and Tick RIsk Score.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Data is limited to nymph ticks from May to September, excluding other life stages and seasons.
• Excludes New York City (NYC), limiting geographic completeness for the state.
