The wave began three weeks earlier. At the same time, the number of reported Covid-19 cases fell steadily from 7.74 to 5.42 cases per 100,000 people in the last three weeks of December. The Covid-19 wave seems to have passed its peak. In absolute figures, more than twice as many cases of influenza as Covid-19 were recorded in the last week of December. These trends have also been observed for respiratory viruses, including influenza and Covid-19, in wastewater in most regions of Switzerland. Around 26.4% of viruses detected at the end of December were influenza viruses, and 10.9% were coronaviruses. The SARS-CoV-2 coronavirus variant most frequently detected in wastewater is XEC.
