In the update from Monday, 24.01.2022, the matrix that shows the infection rate by age group was a particularly brilliant crimson. <img src="{att_link}infectionsbyagegroupmatrix.jpg" href="{att_link}infectionsbyagegroupmatrix.jpg" align="none" caption="Matrix of Infections by Age Group" scale="35%"> If I'm reading this chart correctly, 4.5% of 10 to 19-year-olds were infected with COVID in the week from 10.01 to 17.01. That seems like quite a lot. Switzerland has a 7-day rolling average of about 32,300 cases per day. That makes about 226,000 per week. The latest <a href="https://en.wikipedia.org/wiki/Switzerland" source="Wikipedia">population estimate from 2019</a> is about 8,570,000. That's about 2.64% of the population infected per week at this pace. So, wow. And the positivity rate is a stratospheric, completely out-of-control 41%. <img src="{att_link}positivityrateisover41_.jpg" href="{att_link}positivityrateisover41_.jpg" align="none" caption="Positivity Rate Is Over 41%" scale="35%"> I've heard news that contact tracing is "starting to fall apart a bit". No wonder. On the very positive side, the ICUs are below 80% occupied and holding. The daily average number of deaths is at 12.7. These numbers are much more reassuring than other countries, like the U.S. They indicate that, while a lot of people are being infected at once in Switzerland, the system seems to be able to handle it. Long Covid is still a question mark, but this wave, enormous as it is, is hitting Switzerland fundamentally differently than the others before it.
