The figure eclipses the previous record of 16,164, which was set on Monday.
In capital Copenhagen, the seven-day incidence for the virus is 2,465 per 100,000 residents.
Even before the towering figures posted on Wednesday, Denmark was this week to be reported to have the highest reported Covid-19 infection rates in the world.
“The high infection rate today (Wednesday) can be attributed to a higher PCR test activity just after Christmas,” the national infectious disease agency State Serum Institute (SSI) said in a statement as it issued the latest numbers.
The 23,228 new cases were found amongst 189,512 PCR tests, giving a positivity rate of 12.26 percent. That is considerably higher than earlier in the pandemic but in line with data from Monday and Tuesday this week.
High demand means that authorities are currently giving priority for PCR tests to people with symptoms of the virus or who are close contacts to confirmed cases.
An expert said in response to Wednesday’s figures that “we should all expect to be infected (in Denmark)”.
“When infection numbers are so high, that reflects widespread community transmission,” Henrik Nielsen, professor and senior medical consultant at Aalborg University Hospital’s infectious diseases department, told news wire Ritzau.
“In my view, that means we should all expect to be infected,” Nielsen said.
The total number of persons in hospital with Covid-19 increased by 9 on Wednesday and is now 675. The peak number of admitted patients from the winter 2020 wave reached 964 on January 4th this year, amid far lower infection numbers.
At that time, only a very low percentage of the population had been vaccinated against the coronavirus.
“We find a little bit of hope in hospitals not seeing a parallel increase in hospitalisations. But we are starting to get to the level where it begins to hurt,” Nielsen said.
“When you look at the total of admitted patients with and without the vaccine respectively, the risk (of hospitalisation) is five times higher if you don’t have the vaccine,” the senior medical consultant added.
