COVID-19 Info  COVID Dashboard


Larimer County, CO (December 22, 2021) - State and local health officials are notifying the Larimer County community that the COVID-19 omicron variant was recently detected at multiple wastewater treatment facilities throughout the county.

Municipal sewersheds throughout the county are monitored to detect whether the COVID-19 virus and its variants are present. Many people who have COVID-19 also shed the virus in their stool. This means that wastewater coming from businesses and places of residence can serve as an early warning signal that COVID-19 is present in a specific area.

Scientists are still learning about the omicron variant, however it is clear that it has a significantly greater ability to transmit from person to person than previous variants. LCDHE reminds residents that vaccination and booster doses against COVID-19 remains the most important step that individuals can do for their own health and the health of the community.

In addition to getting vaccinated and wearing a mask, LCDHE recommends that anyone having symptoms of COVID-19 get tested right away. Anyone who tests positive for COVID-19 should isolate themselves from others and contact their healthcare provider to ask about treatment options. There are free drive-thru COVID-19 testing sites in Larimer County, with results returned in 2-3 days:

  • Foundations Church, 1380 N. Denver Ave, Loveland, open 8:00-6:00 M-F
  • Timberline Church, 2908 S Timberline Rd, Fort Collins, open 8:00-6:00 M-F (closed 12/24)
  • Estes Park Event Complex, 1125 Rooftop Way, Estes Park, open 8:00-5:00 M-F

LCDHE also recommends rapid at-home testing, even without symptoms, immediately before gathering with others over the holidays. Testing right before gathering can reduce the likelihood that someone at the gathering is in their infectious period. Rapid tests can be purchased locally in drugstores and Colorado provides no cost rapid tests that can be shipped straight to someone’s home.
