The question worth asking

What can we learn by looking at the data together?

Reported Lyme cases show part of the picture. Tick surveillance, environmental data, and community context add other perspectives. Follow the Buncombe County example to see what becomes clearer—and what questions remain.

01 / The first signal

Start with reported human illness.

Reported Lyme disease cases show where illness was recognized and recorded. They provide a starting point for understanding the county, while leaving questions about infections that were not reported and where exposure occurred.

Cases are reported by county of residence, which may differ from where exposure occurred.

Human surveillanceReported cases provide a starting point for review.
02 / The vector view

Add tick and pathogen data.

Tick surveillance records where ticks have been found. Pathogen testing adds information about what was detected in the samples tested. Together, these data add another perspective to the human case record.

Where, when, and how ticks were sampled shapes what the results can tell us.

Tick and pathogen evidenceTick observations and testing add another perspective.
03 / The shared context

Place the data in context.

Landscape, weather, and community conditions—including access to care—help frame the picture. Considering these alongside human and tick data brings the One Health approach into public health review.

County-level patterns do not establish individual risk or show that one condition caused another.

What's missing from the data matters, too.

Understanding a dataset means knowing where it came from, when it was collected, and what it can tell us. Atlas brings sources, coverage, and limitations into view so public health professionals can interpret the data in context.
