Low, but present in certain areas

Plague is present in some rodent populations in the northern regions of Larimer County, specifically the Livermore, Red Feather and Cherokee Park areas. However, human cases are incredibly rare in Larimer County.

The last Larimer County resident infected was in 2015. Prior to that, the last confirmed case was in 1999, but a Weld County resident camping in Larimer County in 2004 was likely infected in the Red Feather Lakes area.

In recent decades, an average of seven human plague cases are reported each year nationwide according to the Centers for Disease Control and Prevention (CDC). Most human cases in the United States are scattered in rural areas and occur predominantly in two regions:

  • Northern New Mexico, northern Arizona, and southern Colorado
  • California, southern Oregon, and far western Nevada
