Tri-County area sets new record for most COVID cases logged in a day

Wait times exceeded two and a half hours for COVID-19 testing, Jan 3, 2022 at the testing site at Del Mar Park. With the more easily transmissible omicron variant taking shape as the dominant strain, metro area residents flocked to testing sites after the holiday season.

AURORA | Adams, Arapahoe and Douglas counties set a grim new record this past week, with 3,193 fresh cases of COVID-19 reported Dec. 31, the largest single-day jump in cases since the pandemic began.

Health department officials say the counties also broke the previous record for the percent of the population testing positive for the virus over the past seven days. More than 1 in 100 people are said to be infected in each county.

“These next few weeks are likely to be among the most challenging we have faced over the past year,” Tri-County Health Department executive director Dr. John Douglas said this week in a news release.

In the past two weeks, case rates have rocketed by 403% in Adams County, 437% in Arapahoe County and 480% in Douglas County. More than a quarter of all COVID tests are being returned positive in each jurisdiction.

“Although hospitalization rates have not risen as much thus far, hospital capacity in our counties and region remains critically tight,” the same news release said, adding that the omicron variant is believed to be behind nearly all Colorado cases, according to data from the Colorado Department of Public Health and Environment.

More than 75% of Tri-County residents age 12 and older were said to have received initial doses of the vaccine, though only 40%-50% of eligible residents had been boosted.

The health department and the Centers for Disease Control and Prevention both encourage booster shots to protect against the omicron variant, with the CDC recommending boosters six months after receiving the Moderna shots, five months after the Pfizer shots and two months after the Johnson & Johnson vaccine.

“There has never been a more important time to get vaccinated — either your initial series if you are unvaccinated or a booster if you are eligible for one,” Douglas said.

The same news release urged those who test positive to isolate for five days and wear masks around others for another five days, and issued the same advice for exposed individuals who are either unvaccinated or are eligible for a booster shot but have not received it.

Boosted individuals don’t need to quarantine after an exposure but should wear a mask for at least 10 days and get tested within five days, if possible, according the CDC guidelines.

Hmmmm. So why do Adams and Douglas counties think it’s a good idea to disband Tri-County Health Department? With no vision for the future? I guess individuals don’t matter, just uninformed, non-medically trained elected officials who think they know best
