Covid: Half of Europe to be infected with Omicron within weeks - WHO
The World Health Organization has warned that half of Europe will have been infected with the Omicron variant of Covid-19 within six to eight weeks.
Dr Hans Kluge said a "west-to-east tidal wave" of Omicron was sweeping across the region, on top of the surge of the Delta variant already present.
The projection was based on the seven million new cases reported across Europe in the first week of 2022.
The number of infections has more than doubled in a two-week period.
"Today the Omicron variant represents a new west-to-east tidal wave, sweeping across the region on top of the Delta surge that all countries were managing until late 2021," Dr Kluge told a news conference.
He quoted the Seattle-based Institute for Health Metrics and Evaluation as forecasting that "more than 50 percent of the population in the region will be infected with Omicron in the next six to eight weeks".
He said European and Central Asian countries remained under "intense pressure" as the virus spread from western countries into the Balkans.
"How each country now responds must be informed by its epidemiological situation, available resources, vaccination uptake status and socio-economic context", he added.
Recent studies suggest that Omicron is less likely to make people seriously ill than previous Covid variants. But Omicron is still highly contagious and can infect people even if they are fully vaccinated.
The record number of people catching it has left health systems under severe strain.
On Monday, the UK reported a further 142,224 confirmed cases of the virus and 77 deaths. A number of hospitals have declared "critical" incidents due to staff absences and rising pressures caused by Covid.
