Over a week, the number of cases is also at its highest since the start of the pandemic at 46,189 cases, a jump of more than 50 percent compared to the previous week, according to data from Danish health authorities compiled by AFP.
The cases were found from 185,451 PCR tests, giving a test positivity rate of 4.21 percent. That represents the highest test positivity rate the country has recorded since tests for Covid-19 became freely available.
480 people are currently hospitalised with the virus, an increase of 12 since Sunday.
As of Monday, 3,437 cases of the Omicron variant had been identified in the Nordic country. The figure grew by 966 between Sunday and Monday, 631 between Saturday and Sunday, and 560 between Friday and Saturday.
Infectious disease agency State Serum Institute said in a statement Monday that Omicron could become the dominant variant in Denmark this week.
Health authorities said on Monday a third dose of the Covid-19 vaccine would be offered sooner to everyone over 40 to curb the spread of the variant. Around 80.6 percent of the population over five years old has currently received two doses of a vaccine against the coronavirus.
“Due to the new and more contagious Omicron variant the Danish Health Authority has decided to push the third jab for everyone aged 40 and above, so they get the vaccine four and half months after the second jab,” the health authority said in a statement.
By reducing the interval of the doses, “we will be able to enter the winter with better protection for those at increased risk of severe disease and increased immunity in the population,” director Søren Brostrøm said.
A third dose is “safe and effective” as soon as three months after the initial vaccine course, the European Medicines Agency (EMA) said last week.
The Omicron variant appears to spread faster than the Delta variant, making vaccines less effective but causing less severe symptoms, the World Health Organization said Sunday, while stressing that the data remains patchy.
In response to the surge in cases, Denmark reintroduced new restrictions last week, closing schools and colleges, curtailing nightlife and promoting remote working.
