BERLIN (Reuters) - Germany’s public health authority launched a smartwatch app on Tuesday in partnership with healthtech startup Thryve to help monitor the spread of COVID-19 and analyse whether measures to contain the novel coronavirus pandemic are working.

The Corona-Datenspende corona-datenspende.de (Corona Data Donation) app gathers vital signs from volunteers wearing smartwatches or fitness trackers - including pulse, temperature and sleep - to analyse whether they are symptomatic of the flu-like illness.

Results will be represented in an interactive online map that would make it possible - together with other data inputs - for the health authorities and the general public to assess the prevalence of infections down to postcode level.

“If the sample is big enough to capture enough symptomatic patients, that would help us to draw conclusions on how infections are spreading and whether containment measures are working,” said Lothar Wieler, head of the Robert Koch Institute that is coordinating Germany’s coronavirus response.

Germany has the fourth highest COVID-19 caseload behind the United States, Spain and Italy at nearly 100,000 but has kept fatalities down to a relatively low 1,600 thanks to early and extensive testing.

The German authorities have been more cautious than some Asian countries in using digital technology to fight the coronavirus, restrained by Europe’s strict data privacy laws and mindful of public scepticism towards any surveillance reminiscent of Nazi- or communist-era rule.

But a similar approach has been used here to model the spread of influenza while, in the United States, connected 'smart' thermometers distributed by Kinsa Health have offered early insights into how quickly COVID-19 is spreading, the New York Times reported here last month.

READY TO GO

The Corona Data Donation app, available for download in the Google GOOGL.O Play Store and Apple AAPL.O App Store, is voluntary and data would be processed anonymously. To register, users should enter their postcode, age, sex, height and weight.

Data shared by their connected devices would be monitored on an ongoing basis, with telltale readings such as a high temperature or disturbed sleep indicating whether an individual may have come down with COVID-19.

Project leader Dirk Brockmann said he hoped 100,000 people - or 10% of Germany’s smartwatch and fitness tracker users - would sign up. Even 10,000 would be analytically useful, he added.

The Corona Data Donation app was developed in four weeks in partnership with Berlin-based startup Thryve thryve.health, a data-driven 'wearable health' startup which realised earlier this year that its approach could be adapted to detect COVID-19.

Thryve approached the Robert Koch Institute with its findings, said spokesman Sebastian Wochnik. “Their epidemiologists really liked this unique solution. With more data, their models obviously work better,” he said.

Thryve was founded in 2017 as a commercial spin-off from the Fraunhofer Institute for Computer Graphics Research, one of 72 applied research groups under the umbrella of Germany’s Fraunhofer Society.

Another branch of the Fraunhofer Society is involved in developing a European technology platform to support smartphone apps that would use Bluetooth connections between devices to help trace and warn those at risk. [nL8N2BP1OQ]
