It's a confusing situation though, isn't it?
I mean, why would you consult a doctor if you don't have any symptoms?
because the authorities and the regulations of the university said so. i get the confusion, but these measures were established for a reason, and at least i am not in position to debate them at all, so if i was returning from an infected area like northern italy or iran, i would consult a doctor and stay away from public places until the incubation period passes, no questions asked. i'd probably rent a room in a local hotel and wouldn't even return home just to avoid infecting my son, my gf, and especially my mother and stepfather (68 and 70) under any conditions. just common sense i guess.
these phd students aren't virologists themselves to question the measures. one of them followed the protocol, didn't visit the university campus (still infected his wife, they are both in quarantine), the other one went to his regular classes plus visited a language course. now the authorities are trying desperately to track down those who might have contacted this idiot.
and i repeat, i get the confusion. like 3-4 weeks ago, a well-known hungarian infectologist gave an interview about covid-19, and he speculated that the virus can be contained in china, and a pandemic can be avoided. it was a sensible, considered interview from a knowledgeable person. some weeks later, we have ~150 deaths in italy. it's not some joke, it's more serious than most expected.
