You seem to have taken the value from the "14-day cumulative number of COVID-19 cases per 100 000" field on the website of the European Centre for Disease Prevention and Control. This is not the correct unit of measurement. Denmark takes all reported infections during the past 14 days and calculates the average weekly rate per 100,000 people. 37.2 is the biweekly rate, so you will have to divide this by two to get approximately the correct value. The Danish government sometimes makes adjustments to the data. For example, Luxembourg reported -1385 cases on 28 August, but Denmark decided to count this as zero cases on that date.
The UK scored 12.5 last Thursday and probably scores around 17-18 in today's assessment. A new assessment is published every Thursday at 4 PM Danish time. I'd imagine that the border will close for the Czech Republic after today's assessment (effective from Saturday). The rate seems to be between 20 and 30 in Austria, Hungary, the Netherlands and Portugal, so the border closes if more than 5% of the tests are positive but remains open if less than 5% of the tests are positive. I can't find updated information about the rate of positive tests, nor can I find updated infection rates for Switzerland or the microstates.
