Inform people carefully
This application needs a more careful information support for the users. I see too many people studying each and every of the new encounters and analyzing where it could have happened, how risky it could be, etc. People are getting extra nervous and stressed out of nothing. It shouldn't be too hard to add an occasional reminder for the users to stay possibly calm and follow the recommended safety measures. Unless they faced tooany risky encounters within a relatively short period of time. Then the reminder could be different.
