Swiss soldiers fight COVID-19 armed with Bluetooth app

Swiss army conscripts are taking the fight to the coronavirus pandemic by field-testing a Bluetooth-based smartphone app aimed at stopping a resurgence of COVID-19.

The rapidly-created app traces people who have inadvertently crossed paths with someone infected with the virus.

It uses wireless technology with each phone registering the others it has come into close proximity with for a sustained period of time.

For the field test, the infantry recruits went through a normal day: physical training, theoretical study and shooting at targets 300 metres away.

“What we did before was lab tests. Now we’re gathering data on how this app performs in real life,” Simon Rosch, a software engineer with smartphone app developers Ubique, told AFP.

The military base makes a good testing ground because, unlike civilians, soldiers are still allowed to congregate in numbers in close proximity.

Furthermore, they are isolated from the rest of the population inside their barracks at Chamblon, overlooking Lake Neuchatel in western Switzerland.

Breaking the chain

If an app user tests positive for the virus, a coded message is sent to others who might have been exposed to that person, with information as to what they should do next.

The aim is to break the chains of transmission and thereby suppress any spread of the virus as lockdown restrictions are gradually lifted.

Ubique, which developed Switzerland’s main weather app, started working on the new tool only a few weeks ago.

They then joined forces with experts from the Ecole Polytechnique Federale de Lausanne (EPFL) university, which had produced similar ideas.

EPFL does the security, research and Bluetooth tests while Ubique builds that knowledge into the app and comes up with the design and user experience.

“I’m pretty positive about this becoming operational — and it will help,” Rosch said during the test.

“It’s not a magic solution that can make the problem disappear but it’s a good thing that can support us.” (AFP)
