Coronavirus live news: Oxford vaccine trial on hold; climate change 'unabated by lockdowns'


AFP has this interesting assessment of the success – or otherwise – of the various coronavirus tracing apps in Europe:

Germany: no cure-all

Launched in June, the German track and trace app is seen as “an important additional tool for keeping infection rates down” but “no cure-all” according to government spokesman Steffen Seibert.

In a country whose population jealously guards security and control over their personal data, the app has generally been well-received, even by staunch privacy advocates like the Chaos Computer Club.

As of 1 September, the app had been downloaded 17.8m times – compared with an overall population of around 83m – and at the start of July, it had alerted several hundreds of cases of infections.

Iceland: keeping tracks on tourists

Downloads of Iceland’s app peaked shortly after its launch – at an estimated 40% of the population, the user rate is high – but rose again with the start of the tourist season.

Visitors to the volcanic island are encouraged to download the app, not only for its good functionality, but also because it contains links to important Covid-19-related documents and even has an online chat function.

Unlike other tracing apps in use in Europe, the Icelandic app can track an individual’s movements in the case of infection or suspected infection. And, with the individual’s permission, it uses GPS to geo-locate the phone.

Portugal: compatibility issues

Portugal only launched its tracing app this month and it has come under fire from consumer rights groups for perceived loopholes in personal data usage and the dominant role played by tech giants in drawing up health protocols.

In addition, media reports suggest around 800,000 mobile phones – out of an overall population of 10 million – cannot install the app because of incompatible software, ultimately rendering it useless.

France: a flop

The French government launched its StopCovid app at the beginning of June, but by mid-August it had only been downloaded 2.3m times, compared with an overall population of 67 million. So far, only 72 possible risk contacts have been flagged up by the app, while 1,169 users have declared themselves positive.

StopCovid has been criticised by IT specialists with regard to data privacy.

Based on a so-called “centralised” protocol, the French app is incompatible with the majority of its European peers which are “decentralised”.

Under the centralised model, the anonymised data gathered are uploaded to a remote server where matches are made with other contacts, should a person start to develop Covid-19 symptoms.

The decentralised model gives users more control over their information by keeping it on the phone. It is there that matches are made with people who may have contracted the virus. This is the model promoted by Google, Apple and an international consortium.

Favourable marks for Switzerland and Italy

SwissCovid, developed by the EPFL university of Lausanne and based on the decentralised protocol, began testing on 25 May.

Nearly 1.6 million people now actively use the app, which has been downloaded 2.3m times out of a population of 8.5 million.

At the beginning of September, the app was signalling an average 56 infections every day and seems to be generally well accepted by the population.

In Italy, the Immuni app was downloaded 5.4m times, equivalent to 14% of the overall number of potential users (excluding anyone under the age of 14 and people without mobile phones). According to official data, 155 users have declared themselves positive between 1 June and 31 August.

Damp squibs in Norway and Britain

In June, the Norwegian health authorities suspended the locally developed app after the Nordic country’s national data protection agency found it too intrusive.

Authorities are working on a solution which they hope to launch before Christmas and do not rule out resorting to Google and Apple technology.

In Britain, the government revealed its first attempt at a contact-tracing app in May. But in a major U-turn in June, it abandoned the app, based on the centralised model and seen as flawed.

The government, which blamed the problems on restrictions imposed by Apple, has since switched to the decentralised approach. But, as yet, no track and trace app is widely available in much of the UK.

Northern Ireland, however, rolled out its own app at the end of July and it has been downloaded more than 300,000 times by 26 August.
