Colorado coronavirus latest numbers, Oct. 17

The number of people currently hospitalized is 337, and the state's seven-day, moving average positivity rate is 5.21%.

COLORADO, USA — There are 337 patients currently hospitalized in Colorado as of Oct. 17, and the seven-day, moving average positivity rate increased to 5.21%, according to the latest data from the Colorado Department of Public Health and Environment (CDPHE).

Positivity is an important indicator of the status of COVID-19 in the state. The World Health Organization (WHO) in May 2020 recommended that the positivity rate be at or below 5% to contain the virus.

Current hospitalization data are also a key metric because they can be an indicator of whether Colorado’s hospital system is being overwhelmed by the virus. In April, hospitalizations peaked at 888 in one day, indicating the state is on a safer track now to ensure medical centers aren't overwhelmed.

Data are released each day at 4 p.m. Numbers will be updated each day at that time.

Coronavirus data breakdown

CDPHE reports 84,369 people have tested positive for the disease caused by the novel coronavirus, COVID-19. That's up from 82,230 the day prior.  

The graphic below shows case growth, which comes from subtracting the total number of cases from the previous day. A moving average helps capture a trend over a period of time. This removes some noise from the day-to-day numbers. The line on the graph is the seven-day moving average of case growth.


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.


CDPHE reports:

  • 2,176 deaths among people with COVID-19
  • 2,042 deaths due to COVID-19

The majority of deaths — 53% — are among people over age 80; 23% of deaths occurred in people between ages 70-79, and 12% were in people ages 60-69.

The graph below shows the number of people who have died from COVID-19 based on the date of their death.

On May 15, CDPHE shifted to a death documentation difference that divided into "deaths among cases" and "deaths due to COVID-19." Dr. Rachel Herlihy, state epidemiologist at CDPHE, said on May 18 that deaths in the "among" category are from those that tested positive for COVID-19 either before or after death. This is done by medical workers on the front line. Deaths in the "due to" category lag and stem from death certificates that the Centers for Disease Control codes and then sends to CDPHE. On the CDPHE website, it explains the two categories should not be on the same timeline because of reporting differences.


Of those who tested positive for the disease, a total of 8,217 cumulative hospitalizations have been reported.

As of Oct. 17, 337 patients were hospitalized with the disease, according to the most recent data from the Colorado Hospital Association. Within the last 24 hours, 40 patients had been transferred or discharged.

(Note: 78% of facilities reported data as of Oct. 17)

The graph below shows the number of people currently hospitalized with a COVID-19 diagnosis and the number of people who have been discharged within 24 hours. 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.


According to CDPHE, 1,069,977 people have been tested, up from 1,059,831 the day prior, and all 64 counties are reporting cases.
