Coronavirus restrictions are disappearing by the week in a lot of the world, as extra Western international locations cut back their remaining restrictions and inch towards a coverage of dwelling with COVID-19.
The extra transmissible however much less extreme Omicron variant, and its sub-variant, BA.2, have performed a big function in that calculation, convincing many leaders that endemic COVID-19 is in sight.
However what does that imply? Some prime scientists are involved that our understanding of "endemic" is huge of the mark.
"I believe we have executed an enormous disservice utilizing the phrase 'endemic,' frankly," Michael Fraser, govt director of the US Affiliation of State and Territorial Well being Officers, instructed an viewers of largely public well being officers throughout a panel dialogue on the 2022 Preparedness Summit in Atlanta at present.
"It isn't well-understood. It isn't exact," he mentioned.
"There are endemic illnesses that kill 400,000 individuals a yr, like malaria ... and there are endemic illnesses like herpes or HSV-1 which are in half the inhabitants and perhaps you get a chilly sore."
Endemic refers back to the fixed presence or "regular prevalence of a illness or infectious agent" amongst a inhabitants inside a geographic space, in line with the US Centres for Illness Management and Prevention.
Nevertheless it is likely to be too simplistic a time period to use to COVID-19 proper now.
"It does not appear to suit," Lori Tremmel Freeman, chief govt officer of the Nationwide Affiliation of County and Metropolis Well being Officers, instructed CNN on the occasion.
"No time period actually can simply be plugged and performed.
"We do not have all of the items to this puzzle of COVID.
"It looks like a false narrative to speak in regards to the finish. We will plan for it, however we've got to be prepared to return to measures if we see one other variant or one other wave."
It is a urgent dialogue, on condition that the Western world is transferring, albeit at completely different speeds, towards a pre-pandemic set of measures and guidelines.
European international locations "brutally" ended their restrictions within the early a part of this yr, the World Well being Organisation mentioned, and April has seen Germany cut back masks guidelines and the UK scrap all of its prevention measures.
The US, in the meantime, might let its masks mandate in airports and on flights lapse on Monday.
So what is the reply, in line with the consultants?
As an alternative of utilizing "endemic," Mr Fraser mentioned, public well being leaders ought to give attention to what "sustained administration" of COVID-19 may appear like.
Meaning exploring choices like annual booster pictures, retaining some prevention measures in reserve for future outbreaks, and fixed monitoring of the place, when and the way the virus is spreading.
"We have a tendency to think about endemic as actually simply an anticipated illness that is on the market circulating," Janet Hamilton, govt director of the Council of State and Territorial Epidemiologists, mentioned throughout the panel.
"That is positively what COVID goes to be, however the 'anticipated' half continues to be, I believe, such an enormous query on the desk," she mentioned.
