english: So you're not causing disruption to the wider population, you have a case that comes in, you isolate them, you work out who they've come into contact with, who's potentially these opportunities for exposure and then you can follow up those people, maybe quarantine them, to make sure that no further transmission happens.
non_english: Znači ne remeti se šira populacija, novi slučaj se primi, stavi se u izolaciju, sazna se s kim je došao u dodir, ko je potencijalno bio izložen, onda se stanje tih osoba može pratiti, možda se stave u karantin, kako bi bili sigurni da neće doći do daljeg prenosa.
