We got those phone calls from the local authorities about the test results yesterday/Thursday, and they couldn't really tell us about any medical details or what will happen. Will get in touch (haha!) with our local doctor on Monday, maybe he has some more info on the test results themselves, or if they could still be in the incubation period, what the next steps will be, etc.
For now anybody infected or anybody who was in direct contact for more than 15 minutes with them is in isolation at home, as per official order by the local authorities.
