When will you be able to use the Corona App? 

The Corona-Warn-App is available to download on smartphones now and it is scheduled to be available to use at the same time as it is presented to the public. The federal government planned to present the app on Tuesday June 16th at 10.30am.

Will it be possible to download the app to any smartphone? 

Apple and Google say the app can be downloaded to iPhones and Android devices. The iPhone requires the most up-to-date iOS system. This will not work on older iPhones 5, 5s or 6, according to RP Online. On Android devices a 6S version is required for loading the app. Google Play Services must also be running on the devices, which is not the case with the latest Huawei models.

Note that the app is only available to people using the Germany Apple and Google Play stores. So if you have another country's store on your phone you won't be able to download it.

Is there an alternative to the smartphone?

Theoretically yes. For example, key fobs could be equipped with technology. This kind of alternative has not yet been proposed by the government. However, it is quite possible these options will become available at a later date.

Given its fairly long development time, will the app be better than others? 

We have to see how it works in practice. On a positive note, the government, together with SAP and Telekom, the companies commissioned to develop the app, already published the programming data in advance to give experts the chance to test it.

According to the government, 285 suggestions for improvement have been received so far. The feedback is helping to make the app better.

How does the app work?

The Corona-Warn-App uses bluetooth technology to measure the distance and duration of the encounter between people who have installed the app. In order to be effective, the phone needs to have bluetooth turned on at all times. 

Once turned on, the app determines the distance between two phones due to signal strength.

Users will need to be within one and a half metres of each other for a period of time longer than 15 minutes. This distance and time period is used because experts believe it is the minimum required to transmit the virus.

If two phones are within proximity of each other for more than the minimum time, the devices will exchange automatically developed IDs. 

If a person tests positive for the virus, a specially generated code with the test result is sent to that person. This code then needs to be scanned into the person's smartphone.

Everyone who came into contact with them will be anonymously notified. The app also gives the user a notification of their personal ‘risk level for infection'. 

Using this information, a person will then be able to contact the health authorities and ask for a coronavirus test. If they test positive, they can then scan the QR code on their positive test into the app.

At no point in time does this procedure allow connections to be made to you or your location.

Loading the app as well as the responsible handling of your own test result and the feeding of the data is voluntary, not mandatory. The app is not automatically loaded onto phones, and the health authorities have no access to the data.

What do I do if I get a warning from my app? 

You should contact the relevant health authority or your doctor. The warning does not automatically lead to quarantine. However, it would make sense to isolate yourself if possible until you are tested.

An official quarantine can only be imposed by the public health department after talking to them but, to make clear again, they have no access to the data unless you tell them.

What about data protection? 

The government said privacy protection was a “top priority” for them. The decision to store the data collected by the app decentrally, i.e. only on the smartphone owners' phone, was an important step to protect the users' data.

The Federal Commissioner for Data Protection, Ulrich Kelber, has also given feedback into the development. “It is particularly important to me that the relevant documents on data protection, especially the data protection impact assessment, are ready when the app is launched,” he said last week.

“I am confident that the companies and authorities involved will implement our advice as quickly as possible,” said Kelber. The documentation and legal texts available so far have made a solid impression overall.

Can there be manipulation?

Despite recent improvements, IT experts see a possible gateway for abuse when using a particular hotline. The hotline is needed because not all coronavirus test laboratories have a digital connection to the app yet.

If a person using the app is tested in one of these labs and the test is positive, the lab cannot automatically and anonymously feed the result into the app, so that the user can warn other people. The infected person has to call a hotline and answer test questions from call centre staff to ensure that the person has actually tested positive.

The questions and answers must not allow any inference about the person. However, because this is the case, the questions could be answered by another person, who could then trigger a false warning message in the app.

How many people have to participate in order for the tracing app to really work?

Experts estimate that 60 percent of the population should participate for it to really be effective. Health Minister Jens Spahn is pragmatic and says that everyone who downloads the app helps. For the first few weeks, he hopes for several million people to sign up.

How much is the app costing the government?

The development of the app has cost about €20 million. The operation will cost between €2.5 and €3.5 million per month. A large part of the operating costs are accounted for by the hotline, which not only releases positive test results for uploading in the app, but is also available to answer any other questions.

Will the app also be of use to me abroad?

The app is not yet compatible with other European countries but the government says it will work on that in future after introducing it successfully in Germany.

“Through the bluetooth protocol as well as the standards of Google and Apple, there is a means to connect the appropriate roaming functionality,” says the German government.

“We are already in close exchange with other countries, for example with Switzerland, the Netherlands and France, in order to be able to establish interoperability across national borders.”

The government has published more information on the app here.

  1. The store claims that “the app is not available in my country”. I live in Berlin and the phone was bought in MediaMarkt. So yeah, not too good.

Could there be a new wave of Covid-19 in Germany this autumn?

It’s back again: amid sinking temperatures, the incidence of Covid-19 has been slowly rising in Germany. But is this enough to merit worrying about the virus?

Could there be a new wave of Covid-19 in Germany this autumn?

More people donning face masks in supermarkets, friends cancelling plans last minute due to getting sick with Covid-19. We might have seen some of those familiar reminders recently that the coronavirus is still around, but could there really be a resurgence of the virus like we experienced during the pandemic years?

According to virologists, the answer seems to be ‘maybe’: since July, the number of people newly infected with Covid-19 has been slowly rising from a very low level.

According to the Robert Koch Institute (RKI), nine people per 100,000 inhabitants became newly infected in Germany last week. A year ago, there were only around 270 reported cases.

Various Corona variants are currently on the loose in the country. According to the RKI,  the EG.5 (also called Eris) and XBB.1.16 lines were each detected in the week ending September 3rd with a share of just under 23 percent. 

The highly mutated variant BA.2.86 (Pirola), which is currently under observation by the World Health Organisation (WHO), also arrived in the country this week, according to RKI. 

High number of unreported case

The RKI epidemiologists also warned about a high number of unreported cases since hardly any testing is done. They pointed out that almost half of all registered sewage treatment plants report an increasing viral load in wastewater tests.

The number of hospital admissions has also increased slightly, but are still a far cry from the occupation rate amid the pandemic. Last week it was two per 100,000 inhabitants. In the intensive care units, only 1.2 percent of all beds are occupied by Covid-19 patients.

Still, a good three-quarters (76.4 percent) of people in Germany have been vaccinated at least twice and thus have basic immunity, reported RKI. 

Since Monday, doctors’ offices have been vaccinating with the adapted vaccine from Biontech/Pfizer, available to anyone over 12 years old, with a vaccine for small children set to be released the following week and one for those between 5 and 11 to come out October 2nd.

But Health Minister Karl Lauterbach has so far only recommended that people over 60 and those with pre-existing conditions get vaccinated.

“The pandemic is over, the virus remains,” he said. “We cannot predict the course of coming waves of corona, but it is clear that older people and people with pre-existing conditions remain at higher risk of becoming severely ill from Covid-19”

The RKI also recommended that people with a cold voluntarily wear a mask. Anyone exhibiting cough, cold, sore throat or other symptoms of a respiratory illness should voluntarily stay at home for three to five days and take regular corona self-tests. 

However, further measures such as contact restrictions are not necessary, he said.

One of many diseases

As of this autumn, Covid-19 could be one of many respiratory diseases. As with influenza, there are no longer absolute infection figures for coronavirus.

Saarbrücken pharmacist Thorsten Lehr told German broadcaster ZDF that self-protection through vaccinations, wearing a mask and getting tested when symptoms appear are prerequisites for surviving the Covid autumn well. 

Only a new, more aggressive mutation could completely turn the game around, he added.

On April 7th of this year, Germany removed the last of its over two-year long coronavirus restrictions, including mask-wearing in some public places.
