Hover, tap, or search a state to see an educational risk summary. Tick presence does not equal personal disease risk.

What the awareness levels mean

Low

Few or no Lone Star tick reports (limited public data).

Emerging

Reports growing; awareness recommended.

Established

Within the documented Lone Star tick range.

High Awareness

Frequently reported and high alpha-gal awareness.

Tick presence does not equal disease risk

The presence of Lone Star ticks in an area does not mean a bite will transmit disease or cause alpha-gal syndrome. This map is a reminder to take prevention steps where ticks are active. For region-specific guidance, open your state page or contact your state health department.

Disclaimer: Awareness levels on this map are educational and based on publicly reported tick surveillance information. They should not replace official public health guidance from agencies like the CDC or your state health department, and they do not represent any individual's personal medical risk.
