I am interested. Do you have a direct reference please, Olya?
eta: I have since found news reports of research being undertaken and experts' assessments, but nothing published yet?
Not sure how much is published, I've watched many interviews and read articles, not just in English, but other languages as well...
But it's the team around Prof Dr Hendrik Streeck (Uni of Bonn and Uni of Duisburg-Essen), he and his team went to (as some papers like to call it) "Germany's Wuhan" Heinsberg, they basically all moved there and are 24/7 with infected people and in their homes, in full hazmat suits. Prof Christian Drosten has also been doing a lot and Prof Alexander Kekulé, but most of the info I mentioned above I have from interviews and articles with Prof Dr Streeck and his still on-going research, he also rubbished the study on how long the virus allegedly survives (with his own work now showing it doesn't really survive).
He's been on a programme a few weeks ago and said even then that he goes grocery shopping normally, that the possibility of infection via goods is highly unlikely and that it is most important to keep distance and wash hands, he was at the time already in people's homes in Heinsberg and had a good number of swabs and hoovered in air with first results showing the virus doesn't survive or spread via surfaces, none could be detected on surfaces or in the air.
Frankly it's helped me personally to not be too paranoid and not fear grocery shopping, the mail and all that (though I wash my hands much longer now, take care not to touch my face..), we're all more careful, a touch paranoid, sure, but remain sane.
The virus has been found in loos and in stool(!), but all these swabs showed that the virus found in those places are dead, so again you can't catch anything.
I know there are stories where people assume they caught it via a shared pen or a handed over shopping bag, but do they really know? Are they sure? Couldn't it have been via something else? (eg talking). A shared pen is somewhat imagineable, a meeting, many sign something, hand the pen from one to the other, sweaty hands (I remember one colleague using my pen and I only knew they used my pen because when I came back to my desk it was sweaty... still grosses me out a bit!), yadda yadda, but this is literally the only scenario where I can see how one could catch the virus this way, everything else defies logic and current (known to me) research... (say sweaty hands, ie wet warm hands serving for a short time as incubator, many touching one pen within seconds, transfer of the virus and subsequent infection seems to me possible).
Anyway, I'm waffling now... Hope that helps! (incl my unnecessary babble!)
