There is a “very high” risk the Omicron variant of COVID-19 will become dominant in Europe by early next year and lead to a growing number of hospital admissions and deaths, according to the European Union’s public health body.
The European Centre for Disease Prevention and Control (ECDC) said in a report that the Omicron variant of concern (VOC) was likely to overtake Delta within the first two months of 2022.
The news came as the United Kingdom recorded its most daily coronavirus cases since the start of the pandemic on Wednesday (15 December) as a senior British health chief said there could be a “staggering” rise over the next few days.
A further 78,610 COVID-19 infections were reported yesterday in the UK, about 10,000 more than the previous high reported in January.
ECDC said its latest data was not yet sufficient to assess the severity of disease caused by the Omicron variant. However, even if the severity of COVID-19 it caused was lower than that caused by Delta, the increased transmissibility would rapidly outweigh any potential benefits.
“It is therefore considered very likely that the Omicron VOC will cause additional hospitalisations and fatalities, in addition to those already expected in previous forecasts that only take into account the Delta VOC,” ECDC said.
The ECDC said that, without further measures to reduce social contact or increased booster vaccinations, the levels of transmission could overwhelm healthcare systems.
European Health Commissioner Stella Kyriakides said EU countries should immediately plan for increased health care capacity.
“As Europeans we prepare for the end of the year festivities, we cannot throw caution to the wind,” she said in a statement.
ECDC said booster doses would increase protection, according to current evidence, with a higher impact if doses were given to the adult population within a short interval.
Kyriakides said the coming months would be difficult, with Omicron likely to come in a big wave, but with boosters as a “wave-breaker”.
Over 66% of Europeans have received initial vaccinations, but Kyriakides said it was “very worrying” that some countries were lagging, such as Bulgaria, Romania and Slovakia with uptake below 50%.
