DENVER (KDVR) — COVID-19 rates remain low in Colorado, even with the arrival of fall.

The new omicron booster shot has been available in our state for about three weeks, and so far, about 157,000 people have received it. State health officials said about 3 million people are eligible.

The Centers for Disease Control and Prevention said there are no counties in our state with a high community level over the last week.

As of Monday, the state’s seven-day positivity rate was 5.86%, which is up slightly from 5.13% one week ago. The positivity rate measures the amount of COVID positive tests compared to the total amount of tests taken.

Overall, 22 Colorado counties saw a decrease in COVID-19 positivity, 35 counties saw an increase, six counties administered fewer than 10 tests, and one county stayed the same. The state has 35 counties below 5% positivity as of Monday.

According to the Colorado Department of Public Health and Environment, incidence rates are down over the last seven days.

What is the positivity percentage?

According to Johns Hopkins Bloomberg School of Public Health, the percent positive is exactly what it sounds like: the percentage of all coronavirus tests performed that are actually positive, or: (positive tests)/(total tests) x 100%. The percent positive (sometimes called the “percent positive rate” or “positivity rate”) helps public health officials answer questions such as:

  • What is the current level of SARS-CoV-2 (coronavirus) transmission in the community?
  • Are we doing enough testing for the number of people who are getting infected?

The percent positive will be high if the number of positive tests is too high, or if the number of total tests is too low. A higher percent positive suggests higher transmission and that there are likely more people with coronavirus in the community who haven’t been tested yet, Johns Hopkins shared.
