DENVER (KDVR) — After seeing a slight drop in the state’s COVID-19 levels last week, rates are rising again. Incidence rates and overall positivity are up over the last seven days.

The Centers for Disease Control and Prevention has moved 14 counties into the high level for community transmission:

  1. Adams County
  2. Arapahoe County
  3. Boulder County
  4. Broomfield County

As of Monday, the state’s seven-day positivity rate was 12.61%, which is up from 11.13% one week ago. Positivity rate measures the amount of COVID positive tests to the total amount of tests taken.

Overall, 32 counties saw an increase in COVID-19 positivity, 25 counties saw a decrease, two counties stayed the same, and five counties administered fewer than 10 tests.

According to the Colorado Department of Public Health and Environment, incidence rates 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:

  • What is the current level of SARS-CoV-2 (coronavirus) transmission in the community?
  • Are we doing enough testing for the amount 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.
