Outbreaks of COVID-19 are back on the rise in Larimer County. For the first time in nearly two months, new outbreaks were reported to the state. Four newly reported outbreaks push the county s total to seven active outbreaks, with a least one case confirmed to be the highly transmissible Delta variant, the main strain circulating in Colorado. In most instances, the Colorado Department of Public Health and Environment considers an outbreak to be five or more cases within a 14-day window, but two or more cases in health care settings also constitute an outbreak. Given the link between cases, it s safe to say the Delta variant accounts for a significant portion of these cases, said Katie O Donnell, spokesperson for the Larimer County Department of Health and Environment.
