Technical details

• App version: 2.24.1

Describe the bug

The advice given to users with a red tile (increased risk) is:

"Please get tested, for example, with a rapid antigen test, or use self-tests - preferably several times, taking a test every two days. If a test is positive, take a PCR test to confirm the result."

According to the dictionary several means "more than one or two, but not a great many". If no test returns a positive result, it is left to the user to decide how often they should test.

Expected behavior

• If the app advises a user to repeat an antigen test every two days, it should also advise when to stop testing. The current wording suggests that tests should be repeated for an unclear number of times if no test returns a positive result. It would be better if more concrete advice could be given about when to stop testing.

Related questions, although not in the focus of this ticket:

1) the current "test verordnung" covers a RAT at a test center (where I contribute 3 EUR on my own) when I have a red cwa warning. Question: does it cover also these recommended multiple / several tests, or do I get one (the first) for three EUR, and do the following as self-tests?

2) the current "test verordnung" covers a PCR for free after a positive RAT. Question: Do I get this free PCR also after a positive self-test?

[ndegendogo]

Note: my above questions show that the current test verordnung is very ambiguous. Please be aware that it is very hard (if not impossible) to give clear, specific advice based on such an ambiguous Verordnung ...

Still no feedback about how long to continue testing after a red tile?
