Is the Delta Variant Making Younger Adults ‘Sicker, Quicker’?
Fri 06 Aug 2021
Recently, a 28-year-old patient died of Covid-19 at CoxHealth Medical
Center in Springfield, Mo. Last week, a 21-year-old college student was
admitted to intensive care.
Many of the patients with Covid-19
now arriving at the hospital are not just unvaccinated — they are much
younger than 50, a stark departure from the frail, older patients seen
when the pandemic first surged last year.
In Baton Rouge, La.,
young adults with none of the usual risk factors for severe forms of the
disease — such as obesity or diabetes — are also arriving in E.R.s,
desperately ill. It isn’t clear why they are so sick.
working in Covid hot spots across the nation say that the patients in
their hospitals are not like the patients they saw last year. Almost
always unvaccinated, the new arrivals tend to be younger, many in their
20s or 30s. And they seem sicker than younger patients were last year,
deteriorating more rapidly.
Doctors have coined a new phrase to
describe them: “younger, sicker, quicker.” Many physicians treating them
suspect that the Delta variant of the coronavirus, which now accounts
for more than 80 percent of new infections nationwide, is playing a
Studies done in a handful of other countries suggest that
the variant may cause more severe disease, but there is no definitive
data showing that the new variant is somehow worse for young adults.
Some experts believe the shift in patient demographics is strictly a result of lower vaccination rates in this group.
of Sunday, more than 80 percent of Americans ages 65 to 74 were fully
vaccinated, compared with fewer than half of those ages 18 to 39,
according to figures from the Centers for Disease Control and
The vaccines are powerfully effective against severe
illness and death after infection with any variant of the virus,
including Delta. A vast majority of hospitalized patients nationwide —
roughly 97 percent — are unvaccinated. Editors’ Picks A Marriage Stressed by Obsessions and Compulsions Paging Dr. Samantha Boardman, for My Mental Health Why Is It So Hard to Say Goodbye to New York City? Continue reading the main story
don’t think there’s good evidence yet about whether it causes more
severe disease,” Dr. Adam Ratner, associate professor of pediatrics and
microbiology at the New York University Grossman School of Medicine,
said of the Delta variant.
“This may be behavioral — a combination
of the fact that we’re opening things up, and in some places they’re
wide open and there are no masks, which is different from a year or 15,
16 months ago,” he added.
But recently the Delta variant has
offered up a series of unpleasant surprises to scientists, and questions
about the variant’s virulence and capacity to cause more severe disease
are taking on new urgency.
An internal C.D.C. document obtained
last week by The New York Times described the Delta variant as being as
contagious as chickenpox and said it “may cause more severe disease than
Alpha or ancestral strains.”
ages 65 and over represented half of all hospitalized patients at the
end of January, while adults under 50 represented 22 percent, according
to the C.D.C. Now, older people make up just over a quarter of
hospitalized patients, while those ages 18 to 49 account for 41 percent.
about this virus is different in this age group,” said Dr. Catherine
O’Neal, chief medical officer at Our Lady of the Lake Regional Medical
Center in Baton Rouge, La. “We always saw some people who we just said,
‘Why the heck did this get them?’ But that was rare. Now we’re seeing it
“I think it is a new Covid,” she added.
Cam Patterson, chancellor of the University of Arkansas for Medical
Sciences, said the average age of patients admitted to UAMS Medical
Center during the winter was 60; now, it’s 40.
“Our sense is that
younger, healthier people are more susceptible to the Delta variant
than those that were circulating earlier,” Dr. Patterson said.
first Delta variant case was detected at the university hospital on May
1, and by June 17 almost all of the infections were caused by the
variant. “The transition we saw toward younger patients and toward
people getting sick more quickly coincided almost precisely with the
emergence of Delta here in Arkansas,” Dr. Patterson said. “This to us
feels like an entirely different disease.”
Donald McAvoy, 33, a
bodybuilder known as Frue who manages a gym in Jacksonville, Fla.,
didn’t bother to get the Covid vaccine because he thought the virus
affected only older people with health problems.
But toward the
end of June, he had a runny nose, which he thought was a cold or
allergies. His girlfriend insisted he get a coronavirus test. It was
positive, and he was sent home with a small device called a pulse
oximeter to monitor his blood oxygen levels.
Within days, his
condition deteriorated, and he collapsed on the floor of the bedroom.
His blood oxygen levels were at rock bottom: 56. A normal reading is 95
At Baptist Medical Center Beaches, he was put on
oxygen and admitted to the intensive care unit, where he spent 11 days,
an ordeal that he described as “the scariest thing I ever went through,
not only physically but mentally.” His doctor told Mr. McAvoy that he
had been infected with the Delta variant.
He was discharged on
July 8, tethered to an oxygen tank. He has lost 25 pounds, and has been
warned it will take four to six weeks of rest and respiratory therapy
before he can return to work. He fears it may be longer.
