The number of new infected with the corona virus has once again dropped drastically. Why so? Virologist Andreas Cerny classifies.
in short needed
- BAG reported about 23,300 new corona infections this week.
- Still more than 37,738 new infections were confirmed in the past week.
- Reason: The wave with the BA.5 variant is over – but the next one may come.
This week, there has been a significant drop in confirmed infections with the coronavirus in Switzerland: while there were 37,738 cases last week, BAG reported only 23,348 on Tuesday.
But why are the numbers diving so high at the moment? Until recently, did more people get tested just because they wanted to go on vacation?
No, says virologist Andreas Cerny. “We know the number of unreported cases was very high,” he tells Nau.ch. But he does not believe that summer vacations have anything to do with the development of confirmed corona infections.
The reason for the number diver is different: the number is an indication that the wave is over with the last major Omicron variant in Switzerland.
new form of corona virus is coming
Cerny explains: “The BA.5 variant has increased in the last few weeks. Now it’s closing because a lot of people have already been sick. At the moment, the corona virus hardly finds people who have no defense. ,
He compares this to the earlier ommicron waves. “If you look at the curve, you can see that the first peak was in January with the emergence of omicron. The second peak came when BA.2 omicron variants dominated.
In short: “The wave is blowing.” The BA.4 variant is making itself felt now, but Cerny doesn’t expect a big hike here.
Have you ever been infected with Corona?
One wave is over – but the next one may already be around the corner: “It is possible that the Centaurus Omicron variant will rise again here as well. The mutation first appeared in India and is spreading there.”
In Switzerland, however, we may not be as sensitive to this: “In India, Omicron variants were not as common as they are here. He already had several. So maybe we’re better protected.”
