COPENHAGEN, Feb 16. (Xinhua) -- Wastewater monitoring shows an alarming increase in the number of coronavirus infections in Denmark, even though the number of positive PCR (polymerase chain reaction) tests, hospitalizations and deaths appears unchanged, the Statens Serum Institute (SSI) said in a weekly report released on Thursday.
According to the SSI, the new COVID-19 Omicron subvariant XBB.1.5, which was spreading rapidly in the United States at the end of last year, is now the most common strain in Denmark, accounting for " approximately 26 percent of all cases."
