Drive-up testing for the novel coronavirus in Denver closed early on Saturday because of high volume, as the state announced it has 101 positive cases of the highly contagious respiratory disease.

The drive-thru testing at the Denver Coliseum was supposed to be open until 2 p.m., but health officials cut the line off after 200 cars. The Colorado Department of Public Health and Environment said it will post next week’s schedule and locations on its website when they are available.

State health officials announced Saturday that 24 more people have tested positive for COVID-19. The new cases include people from:

Adams County – 3

Arapahoe County – 3

Denver County – 5

Eagle County – 4

El Paso County – 1

Gunnison County – 2

Jefferson County – 2

Mesa County – 1

Pitkin County – 1

Weld County – 1

Out of state – 1 (currently in Denver County)

Test results include 20 from the state lab and four from private testing facilities as health officials ramp up testing. About 800 people have been tested since Feb. 28, health officials said.

Public health officials urged people who have symptoms or believe they have may have been exposed to COVID-19 to call or email their doctor first for guidance.

“Any medical provider with a relationship with LabCorp or Quest Diagnostics can test, but be sure to contact your provider ahead of time because many providers have centralized sites for testing due to safety precautions,” state health officials said in a news release.

The state on Saturday announced it was restricting visitation to skilled nursing, assisted living and intermediate care facilities to protect health care workers and those most vulnerable to the novel coronavirus.
