3,628 further Covid-19 cases as 35% now Omicron variant

Further restrictions to curb the spread of the Omicron variant are to be announced this evening.

A further 3,628 cases of Covid-19  have been confirmed as tighter restrictions on hospitality and events are expected to be outlined this evening. 

The Health Protection Surveillance Centre has estimated that 35% of reported cases are now due to the Omicron variant.

As of 8am today, 420 Covid-19 patients are hospitalised, down 23 from yesterday's figures.

Meanwhile, 105 people with Covid-19 are in ICU, a decrease of three from yesterday. 

Chief medical officer Tony Holohan has said that the Omicron variant it is expected to dominate by Christmas at a special briefing this Friday afternoon.

Modelling for potential scenarios shows between 8,000 and 20,000 new cases per day depending on the restrictions and reductions in contact in place.

The Omicron variant is estimated to be up to four times more contagious than the Delta variant.

Professor Philip Nolan, chair of the epidemiological modelling group, said it also shows “our most optimistic projection would be for between 650 and 1000 people in hospital in early January.” 

He said the “more pessimistic” scenarios could see over 2,000 people in hospitals.

Analysis shows cases are dropping among children aged five to 12, but rising among those aged 19 to 24 and 24 to 34. Dr Holohan said these are “likely” to be Omicron.

The variant's growth rate is estimated at between 20% and 40% meaning it is up to four times more contagious than the Delta variant.
