Recently, prairie dogs found at the Arizona Game and Fish Department Garland Prairie research plot tested positive for plague. Additional testing is pending and a treatment response is being determined.

After fleas tested positive for plague last month near the Red Lake area north of Williams, the Arizona Game and Fish Department (AZGFD), together with Kaibab National Forest, recently applied insecticidal dust to prairie dog holes for fleas. The areas that were treated with dust are near Williams and in the Flagstaff-area.

Coconino County Public Health Services District (CCPHSD) officials confirmed that fleas collected in the Red Lake area, approximately five miles northeast of Williams, tested positive for plague (Yersinia pestis).
