These 14 counties have 0% COVID-19 positivity; incidence rates rose slightly

DENVER (KDVR) — After stealth omicron was detected in Denver last week, where do COVID-19 rates stand in Colorado?

As of Monday, the state’s seven-day positivity rate was 2.56%, which is down from 2.93% seven days ago. Positivity rate measures the amount of COVID positive tests to the total amount of tests taken.

Over the last week, 14 counties dropped to 0% positivity. Overall, 29 counties saw a decrease in COVID-19 positivity, 23 counties saw a slight rise, seven counties stayed the same, and five counties administered fewer than 10 tests.

According to the Colorado Department of Public Health and Environment, incidence are up slightly over the last week.

What is the positivity percent?

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:

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.
