Show date of Low-Risk encounters

[Ein-Tim]

NEWS

This has been introduced with version 1.13: corona-warn-app/cwa-app-ios#1882

Current Implementation

Currently, when you had a Low-Risk encounter you just see that you had one (and that the app says it is Low-Risk) and no more information about the encounter.

Suggested Enhancement

Please inlcude the information when the encounter happend ("dd.mm.yy"), how it is done by High-Risk encounters.

Expected Benefits

The user would know what he/she has done on this day and so know if there is anything special to do. (had I many or just a few contacts on that day/were I on a train this day (where the distance measurement is not that good), etc.)

Additional Inforamtion

I know that the RKI denied to show more information about Low-Risk encounters, but could you please bring up exactly this suggestion and let us know what they are thinking?

Hello @Ein-Tim,

thanks for sharing your idea. I have created a JIRA ticket and assigned it to @hermesmar .

Thanks,

Pls. also note issue >Display of "Tage seit letzter Risiko-Begegnung" is irritating< at corona-warn-app/cwa-documentation#433.

Another reason why cwa should show this to the user:
a user that gets such a warning without any details is worried, and trying to find out more details about the time of encounter, he finds the EN log file, and misunderstands these timestamps.

I have seen several such misunderstandings here in the discussions and questions again and again; we may assume that it happens quite often.

cwa showing the times (with day granularity) should prevent such misunderstanding.

I agree with what @ndegendogo wrote: I was in that very situation of misinterpreting log data, even going so far to write a little app that takes that log-json and puts the dates of what I thought were matches in a calendar view. When I discussed this idea and the prototype with friends and other people many of them wanted to have this app.

It was only later (luckily - being a responsable person - before providing this app to anybody) that I checked my assumptions more thoroughly. I realized that propably identified the date when an infected person uploaded the keys to the CWA server and not the date of encounter - essentially rendering my app useless.

The takeaway from this little story for me is that people also want to know when they had low risk encounters.

For me personally for example this could be useful to avoid places in which I repeatedly encountered people who later reported an infection even if previous encounters didnt put me at risk (i.e. they were low risk encounters).

This is only worthwhile if you can see days since last encounter for each of the risk categories.

Currently you might have High Risk 7 days ago, then a day later you have still High Risk but 3 days ago. Was that three days ago now High Risk or Low Risk? Super confusing.

While waiting for this change to be implemented. Is my logic correct when saying that the day the "low-risk" warning disappears from the app, is 14 days after the "low-risk" exposure happened?
Since the day the warning disappears is when data from 14 days ago is deleted, hence there is no data there to match the exposure anymore.

[Ein-Tim]

Yes your assumption is correct if the Encounter is more than 14 days old the App will not show the Encounter anymore

Regarding OP: a possible extension of this in form of a graph which shows contacts over time has been proposed here: #205 🙂.

[ohobby]

From my own experience, I can report that reporting that you have had one or more low risk encounters, but you don't know when it happened, causes many people to panic and/or brood a lot about when and where it happened.
My partner and some friends are such candidates.
For this reason it would be very important that the date of the encounter is mentioned very quickly, even in the case of low risk encounters. This would help some users not to panic or brood. And prevent many requests to the health department and/or doctor.

[daimpi]

@ohobby

I agree, that displaying this information would be really helpful.

Btw: if you have an Android device you can get this functionality (+more) already now by using @mh-'s corona-warn-companion. You don't even need root, you can simply run it in RaMBLE mode (for future encounters) 🙂.

[vaggelisdouros]

Trying to balance privacy vs. revealing some meaningful information, may I suggest/re-iterate that, as a minimum, the app should display whether a low-risk was "old" or it is a "new" one?

Motivation: imagine that today the app shows 1 low-risk encounter, meaning that, during the last 14 days, I had a contact with someone who tested positive.

If the next day the app shows again 1 exposure with low risk, can we at least know whether it corresponds to the previous case (the "old" encounter) or whether that encounter disappeared but a new encounter appeared?

[daimpi]

@vaggelisdouros currently as a workaround you can check the EN log to find out whether this is a new encounter (as log as you're under iOS).
But the situation will improve significantly once the exposure history gets implemented 🙂.

[Ein-Tim]

Starting with v 1.12.0 there will be the exposure history shown in the App (corona-warn-app/cwa-app-ios#1801). This will be shown for "High"- and "Low-Risk" encounters.
This would indirect introduce this too - maybe @dsarkar could update us about this Issue.
Why won't you show the date of "Low-Risk" encounters directly, but only in the exposure history?

[GisoSchroederSAP]

Let me quickly give an answer on-first-shot: When the concept of "red and green only" was established in the very beginning of the CWA, is was quite obvious: Once a warning with "red" risk appears, the user has to take action. A dedicated function was implemented to support this "red" state.
In contrast to the red card, the "green" status doe not require special attention - therefore (with respect to the limited time and resources), there the function to grab the date of the last green encounter was not implemented yet.
Yes, it seems to be inconsistent. Yes the the exposure history will show both types, still it will require two different methods to gather the respective information for red versus green encounters.

I hope, this explains the "Why?" at the current stage.

[Ein-Tim]

Thank you so much for answering @GisoSchroederSAP.❤️

Just btw:
You could get the membership of the Corona-Warn-App Organization here on GitHub (or make it public) so that it is clearer that you are a member (yes your Name is kinda telling this, but I also saw other users with SAP in their names here and it seemed like they had nothing to do with the CWA project at all). 🙂
