While this may seem like a risky move while Omicron continues to infect tens of thousands of people each day, a number of Swiss experts believe quarantines and, in some cases testing, are useless.

As nearly 215,000 people in Switzerland are currently confined to their homes because they either tested positive or were in contact with an infected person, some health experts are calling for the end to quarantines.

They question the usefulness of quarantines for preventive purposes, as well as mass testing, in curbing the spread of the Omicron variant.

“Currently, counting undeclared cases, we have between 50,000 and 100,000 infections per day. One can wonder if someone who is in quarantine because he is a contact case still represents a greater risk than others who move around freely in society”, said Jürg Utzinger, director of the Tropical and Public Health Institute.

Under these circumstances, and given the economic costs of home confinements, it would be better to abolish quarantines and widespread testing until the number of cases drops to a much lower level, he said.

And once the numbers return to a lower threshold and become more manageable and easier to trace, both testing and quarantines could return to prevent infections from soaring again, Utzinger pointed out.

At the moment, however, it is necessary to establish priorities by reserving PCR tests for symptomatic people or those who work in exposed sectors, such as healthcare, according to Utzinger.

In the meantime, “we must temporarily suspend mass testing so as not to overload the laboratories”, he noted.

Philipp Walter, president of the Swiss Union for Laboratory Medicine, agrees. “You have to ask yourself how much screening still makes sense. Testing does not cure. And if so many people are infected, it is better to assume that everyone can be positive”, he said.

As for immunologist Daniel Speiser, quarantines are not very useful, but screening remains important.

“Even if the results of the PCR tests arrive late, they still have the effect of curbing contamination,” he noted.

On the positive note, and echoing the view of many other health experts, Speiser believes that Omicron will put an end to the pandemic, as this variant will not be supplanted by another in the foreseeable future.

“Omicron is so successful that it is difficult to beat it,” he quipped.

Utzinger agrees: “We will very soon experience the peak of this wave and the number of cases will then decrease as quickly as it has increased”.

What other, looser measures are being proposed in Switzerland?

After Spain has proclaimed it wants to stop counting daily infection rates and instead treat Covid the same way as a seasonal flu — that is, with selective surveillance — some Swiss experts said they support this approach.

Valérie D’Acremont, an infectious disease specialist at the University of Lausanne, believes Switzerland should follow the Spanish strategy and adopt the same monitoring system as it already has in place for counting flu cases.

This new approach would signal the transition from a pandemic mode to an endemic one, meaning the disease is commonly found among the population and its evolution has become predictable.

Health Minister Alain Berset has recently mentioned this transition “from a pandemic to an endemic phase with high levels of immunity already reached” in Switzerland.

Even so, it is too early to end quarantine and testing, Berset pointed out.

“We can’t say that this week, or the next, it will be possible to remove all the measures that are currently in place”.
