LONDON — Greater than half of individuals in Europe could possibly be contaminated with the Omicron variant of the coronavirus within the subsequent six to eight weeks, the World Well being Group warned on Tuesday, amid “a brand new west-to-east tidal wave sweeping throughout the area.”
“The area noticed over seven million circumstances of Covid-19 within the first week of 2022, greater than doubling over a two-week interval,” Dr. Hans Kluge, the company’s regional director for Europe, stated at a information convention.
Whereas coronavirus vaccines stay remarkably efficient at stopping extreme sickness and dying, the company cautioned in opposition to treating the virus just like the seasonal flu, since a lot stays unknown — significantly concerning the severity of the illness in areas with decrease vaccination charges, resembling Japanese Europe.
The W.H.O. has cautioned for months that booster photographs might worsen vaccine inequality world wide, however Dr. Kluge stated on Tuesday that they’d play a vital position in defending essentially the most susceptible folks from extreme illness and must also be used to guard well being employees and different important workers, together with lecturers.
Since Omicron was first detected in late November, it has torn throughout the planet at a tempo unseen throughout two years of the pandemic. As mates, co-workers and relations check optimistic, the truth that the virus is shifting shortly and extensively has been a defining function of this wave of an infection.
However the steep rise that Dr. Kluge cited, based mostly on forecasts by the Institute for Well being Metrics and Analysis, is a stark paradigm shift. Though the institute’s fashions have steadily been criticized by specialists, it’s clear that the virus is spreading shortly. Even when many individuals keep away from extreme sickness, the virus guarantees to trigger societal disruption throughout the continent.
Whereas a lot of the general public dialogue has revolved round whether or not this was the second when governments ought to shift insurance policies and restrictions to deal with the coronavirus as an endemic illness — eradicating most restrictions and permitting folks to handle danger in a approach just like the best way they do with influenza — the W.H.O. stated it was too early to name this virus endemic.
Catherine Smallwood, a W.H.O. senior emergencies officer, stated that one of many key elements in declaring the virus to be endemic was some sense of predictability.
“We’re nonetheless methods off,” she stated. “We nonetheless have an enormous quantity of uncertainty.”
Dr. Kluge added that there have been just too many unknown elements, together with precisely how extreme Omicron is for unvaccinated folks and the way excessive the chance is of an infection resulting in “lengthy Covid” signs.
“I’m additionally deeply involved that because the variant strikes east, we’ve but to see its full affect in nations the place ranges of vaccination uptake are decrease, and the place we are going to see extra extreme illness within the unvaccinated,” he stated.
Nations within the Balkans and Japanese Europe, the place Omicron is simply beginning to unfold extensively, have a lot decrease charges of vaccination than these in Western Europe.
Regardless of the widespread stage of an infection, Dr. Kluge cited knowledge from Denmark suggesting how efficient vaccines stay. The hospitalization rate for unvaccinated people within the newest wave was “sixfold greater than for individuals who had been absolutely vaccinated within the week over Christmas,” he stated.
“Permit me to reiterate that the at present permitted vaccines do proceed to supply good safety in opposition to extreme illness and dying, together with for Omicron,” he stated. “However due to the unprecedented scale of transmission, we at the moment are seeing rising Covid-19 hospitalizations. It’s difficult well being techniques and repair supply in lots of nations the place Omicron has unfold at velocity and threatens to overwhelm in lots of extra.”
The Coronavirus Pandemic: Key Issues to Know
He added: “For nations not but hit with the Omicron surge, there’s a closing window to behave now and plan for contingencies.”
One of many central struggles of governments throughout Europe has been making an attempt to maintain faculties open, and Dr. Kluge described these efforts as important.
“Faculties must be the final locations to shut and the primary to reopen,” he stated, though he added that “the numbers of contaminated individuals are going to be so excessive in lots of locations that faculties in lots of nations are going to be unable to maintain all lessons open” due to sickness and employees shortages.
An instance of that strain was obvious this week in France, the place 10,452 lessons had been canceled on Monday, based on the federal government. Prime Minister Jean Castex stated that going ahead, schoolchildren within the nation could be allowed to do self-tests as an alternative of P.C.R. assessments if one among their classmates examined optimistic, in an try and hold the schooling system functioning.
“If we had been to close down lessons as quickly as there’s one first case, taking into account the explosion of Omicron, all French faculties could be closed in a matter of days,” Mr. Castex advised France 2 tv.
However as nations think about shortening isolation intervals for individuals who check optimistic to restrict the impact on important providers, Dr. Kluge stated that “any choice to shorten really helpful quarantine or isolation intervals must be taken together with detrimental Covid-19 assessments and solely when thought of important to protect crucial service continuity.”
