Latest COVID-19 numbers: Omicron surge continues in Colorado

Here are the numbers for how many vaccines have been distributed in Colorado, how many new cases of COVID have been reported, and current hospitalizations.

DENVER — A total of 72.6% of Colorado's population has received at least one dose of the COVID-19 vaccine, and 65.4% is fully vaccinated, according to the latest data from the Colorado Department of Public Health and Environment (CDPHE). 

Statewide, there are 1,488 patients currently hospitalized with COVID-19 as of Jan. 11, and there have been an average of 13,083 new cases of the virus per day over the last seven days.

Hospitalizations are a key metric for health officials since they indicate whether the healthcare system is being overwhelmed by the virus. Since vaccines have become widely available, doctors have said the vast majority of new COVID-19 hospitalizations are people who have not received a shot.

Variants

Over the last week that data was collected, 100% of tested COVID-19 samples in Colorado were the omicron variant.

See more data from CDPHE about variants here.

The omicron variant was detected in November in the region of southern Africa.

On Dec. 2, Colorado's first case of the omicron variant was detected in Arapahoe County. 

Colorado was the third state to detect the omicron variant.

The delta variant, first detected in India, is more contagious and may cause more severe illness than the original strain of COVID-19.

Public health officials said while there is a slight decrease in vaccine efficacy with the delta variant, there is still a lot of protection since the level of protection was so high to start with.

Infectious disease specialists also said for the smaller number of breakthrough cases, that most of them are asymptomatic or mild symptoms.

Vaccines

Everyone in Colorado who is 5 years old or older is now eligible to receive a COVID-19 vaccine.

Of those who are currently eligible, 78.48% have received at least one dose of the vaccine and 70.68% are fully vaccinated, according to CDPHE data. 

An estimated 429,801 Coloradans are younger than 5 and are currently not eligible to receive a vaccine.

About 28.5% of Coloradans have received an additional booster dose of the vaccine.

The pie chart below shows Colorado's vaccination progress: 

Colorado received its first shipment of the COVID-19 vaccine on Dec. 14, 2020. The U.S. Food & Drug Administration (FDA) in December authorized emergency use for both the Pfizer vaccine and the Moderna vaccine. Both were shown to be around 95% effective in clinical trials and require two doses. Johnson & Johnson's vaccine was granted emergency use authorization on Feb. 27, 2021. It was shown to be 86% effective at preventing severe disease and requires one dose.

The Pfizer vaccine is the one shot that has been approved for children between 5 and 17. 

Hospitalizations 

The graph below, which is updated weekly, shows the number of people currently hospitalized with a COVID-19 diagnosis. 

This is a key metric because it can be an indicator of whether or not Colorado’s hospital system is being overwhelmed by the virus.

In the week of Dec. 12, the hospitalization rate among people who are fully vaccinated was 4.0 COVID-19 hospitalizations per 100,000 people, according to CDPHE. The case hospitalization rate among people who are not vaccinated was 51.5 COVID-19 cases per 100,000 people during the same week.

Cases

This chart is updated weekly.  

In the week of Dec. 19, the the case incidence rate among people who are fully vaccinated was 233.6 COVID-19 cases per 100,000 people, according to CDPHE. The case incidence rate among people who are not vaccinated was 582.6 COVID-19 cases per 100,000 people during the same week.

The number of new cases reported in a single day previously peaked on Nov. 12, 2020 with 6,801 Coloradans testing positive for COVID-19. That was surpassed on Dec. 28, 2021 when 7,072 cases were reported. Daily case counts have continued to climb dramatically since then.

Positivity  

See Colorado's latest positivity rate in the graphic below.

This chart is updated weekly.

Positivity is the number of tests that come back with a COVID-19 result. Above 10% could be an indicator that not enough testing is being done and that only people likely to have COVID are getting tested. The World Health Organization recommended in May 2020 that the positivity rate should be even lower, 5%, to contain the virus.

Fatalities 

CDPHE reports there have been: 

  • 10,528 deaths among people with COVID-19
  • 10,965 deaths due to COVID-19

It's worth mentioning that deaths are a lagging metric, meaning that there are often multiple days between when someone dies and when that information is distributed to health officials.
