On February 10, 2021, Colorado noted that a temporary technical issue occurring on February 9, 2021, caused their dashboard to show incomplete case counts, while testing and percent positivity data did not update. As a result, we were unable to update testing data on February 10, 2021. A full update for all affected metrics is anticipated on February 11, 2021.

On January 26, 2021, Colorado reported that it would be adding over 3,000 past-dated cases from last year, particularly November and December 2020, reported by email and fax to its cumulative figures. This will cause larger than normal case counts over the next few days. We urge caution when using data from this period.

As of December 11, 2020, we are switching our deaths source for Colorado from deaths due to COVID to deaths among cases. Colorado's deaths due to COVID-19 metric is lagging its deaths among cases metric. On September 1, 2020, there was only a 97 difference between the two figures: 1946 deaths among cases, vs. 1849 deaths due to COVID. On December 11, 2020, there is now a 759 difference—3759 deaths among cases, as opposed to 3005 deaths due to COVID. This means 20% of deaths among cases do not have death certificate data, vs. 5% in September, indicating a lag.

We are also capturing a confirmed/probable breakdown from May 15, 2020 onward, which we did not capture previously since it was not provided for due to COVID.
