telegraph | The omicron epidemic is being driven by young, vaccinated people, according to mounting data from countries as diverse as the UK, Denmark and South Africa.
The new variant has now been detected in more than 60 countries, including 24 in Europe, with a similar pattern of infection and characteristics being reported across the globe.
But while the speed and the vaccine evading properties of the virus are now established, there is as yet no firm verdict on its virulence or severity.
“Generally those first cases are in relatively young, relatively healthy and – in the context of Europe – in relatively highly vaccinated groups,” Dr Catherine Smallwood, a senior emergency officer at the World Health Organization’s Europe office, told the Telegraph.
Data from Denmark – a world leader in genetic sequencing – shows that, of 3,437 omicron cases detected, just over 70 per cent have been among those younger than 40, according to the breakdown from the Statens Serum Institut published on Monday.
Some 75 per cent of these cases were in fully vaccinated individuals, the institute added, confirming that even the double jabbed can carry the virus.
Daily cases in Denmark have surged by a third since early December, despite almost 80 per cent of the population being double vaccinated.
The country tightened restrictions at the end of last week – introducing a midnight curfew on bars and restaurants and closing schools early for the Christmas holidays – but experts estimate omicron could become the dominant variant as soon as Wednesday.
Neighbouring Norway, which has so far reported 958 cases, also introduced new Covid control measures on Monday, with the Prime Minister warning that the situation is “serious”.
Preliminary data suggests the pattern of spread is, so far, similar worldwide.
Analysis from the European Centre for Disease Control found 72 per cent of early cases were in those under 40, while the US said the majority of the 43 infections detected so far were in this same age bracket. American authorities also revealed that 79 per cent of people infected were vaccinated.
Prof Emmanuel Andre, head of the national reference lab for Covid-19 in Belgium, said the country is two weeks behind the UK, where omicron cases jumped by 50 per cent on Monday and the first death with the variant was confirmed.
“Most infections documented at this early stage are among younger age groups,” he told the Telegraph, citing work, travel, sports competitions and schools as possible explanations. But Prof Andre added that Christmas celebrations could “amplify” omicron’s spread.
