The US health care system, already straining to contain a Delta spike, must now deal with Omicron. One expert predicts that Omicron will infect 20% to 30% of health care workers.
This is what exponential growth looks like.
When President Joe Biden addresses the nation tonight about the danger the Omicron variant of COVID-19 poses to public health, he will be armed with data to bolster his warning that “we are looking at a winter of severe illness and death for the unvaccinated—for themselves, their families and the hospitals they’ll soon overwhelm.”
The first case of Omicron in the United States surfaced on November 29. In the first week of December, according to the Centers for Disease Control and Prevention (CDC), Omicron accounted for 1% of new cases in the US. For the week ending December 11, the variant comprised 12.6% of new cases. As of yesterday, according to the CDC, Omicron made up 73% of new cases of COVID-19—all of that growth happening in about 20 days.
The data streaming in from state health departments include a long list—states where Omicron has been diagnosed—and a short list, states where is has not yet appeared. The latter list comprises 2 states: Oklahoma and South Dakota. As of this update.
Health care officials in the US and with World Health Organization warned that this would happen, noting that Omicron cases double every 1.5 to 3 days. Tedros Adhanom Ghebreyesus, WHO general director, said at a press conference last week that “Omicron is spreading at a rate we have not seen with any previous variant.”
He urged that people again utilize the nonpharmaceutical mitigation efforts that had been so relied upon before the launch of COVID-19 vaccines. “It’s not vaccines instead of masks,” Tedros said. “It’s not vaccines instead of distancing. It’s not vaccines instead of ventilation or hand hygiene. Do it all. Do it consistently. Do it well.”
Health officials worry that initial clinical investigations of Omicron that indicate that it has much milder symptoms than Delta might have made individuals unaware that the variant’s hyper infectivity will further strain health care systems already battling a surge in Delta cases.
“Even if Omicron does cause less severe disease, the sheer number of cases could once again overwhelm unprepared health systems,” Tedros said last week.
Linda Spaulding, RN-BC, CIC, CHEC, CHOP, and a member of Infection Control Today®’s Editorial Advisory Board, yesterday laid out just how much strain health care professionals in the US feel in a Viewpoint ominously headlined: “Health Care System on Verge of Collapse.” In it, Spaulding asserts: “I feel disaster coming our way. I think we are about to experience something that will knock the breath out of people very soon.”
Spaulding said that the portion of the public that remains unvaccinated puts health care workers in jeopardy and forces them to work nonstop. “There is no one left to cover sick calls and vacations now. There are no vacations for nurses and doctors. There are no Christmas celebrations or New Year celebrations for these workers.”
Spaulding’s concerns were echoed yesterday by Michael Osterholm, PhD, MPH, director of the Center for Infectious Disease Research and Policy and the University of Minnesota, who told CNN that even if Omicron proves to be less severe “we are going to see 20%, 30% of health care workers getting infected, who will then be off of work in a health care system right now that is already stretched to the point of breaking.”
Some states, universities and businesses have implemented lockdowns in response to Omicron’s spread. Vaccinated individuals who want to gather for the holidays have been urged to rely on COVID-19 testing to ensure that they don’t endanger those most vulnerable. However, there doesn’t seem to be enough COVID-19 tests to meet a surging demand.
As Axios reports this morning: “Less than a week before Christmas, walk-up testing lines are hours long in cities across the country, pharmacies are running out of testing appointments and rapid at-home tests are frequently nowhere to be found.”
In his speech tonight, Biden is expected to announce that the US will buy a billion rapid tests, and start mailing them to American households next month.
The desire of many Americans to gather over the holidays in part spurs this increased demand for rapid tests. Anthony Fauci, MD, the director of the National Institute of Allergy and Infectious Diseases and the top White House medical advisor, said on This Week Sunday that individuals who’ve been vaccinated and have gotten a booster should be able to travel and gather for the holidays safely.
Fauci said that “if you are vaccinated and boosted and are prudent when you travel, when you're in an airport, to be wearing a mask all the time. You have to be wearing a mask on a plane. Do not do things like go to gatherings where there are people who you do not know what their vaccination status is.”
