CPW has had ongoing surveillance for the disease throughout the state since it was identified in April of 2020. Garfield and Saguache are new counties identified as having RHDV-2. The new discoveries mean that 15 Colorado counties have had positive tests for RHDV-2. The positive case from Garfield County was discovered just south of the town of Silt. The cottontail was submitted to a CPW wildlife officer by a landowner whose dog had found the carcasses and brought them home over a period of a few weeks.
