@SnapdragonQ I think you're overdoing it. If I remembered correctly this virus lives only a hour or so on paper and wood. And up to 3 hours on metals and and plastic.
Washing hands is only necessary if you touch surfaces shortly after a contaminated person touched it.
I wish you less fear. Please stay healthy in a more relaxed way.
In the US, doctors are warning several hours on paper and cardboard. Putting 2 + 2 together means that the mail carrier or delivery person could be a source. And, up to 2 to 3 days on stainless steel, hard surfaces, tyvec envelopes, and plastics.
We are an at risk family so I'd rather be over cautious, especially because I understand more than most the vectors of spread and how viruses behave.
I think part of what is causing so many to feel so uncomfortable is that there is much conflicting information. For instance, here in the US we (collective we) were initially told this is primarily a risk for the elder population or those with underlying conditions.
However now, data is showing middle age people are filling up the hospitals in New York. When I look at the stats for various places here (US) where there is a break down by age, in some places it's the middle aged folks who are getting hit the worst.
Of course we don't fully know what we need to know because this is so new.
Ergo, I'm following the latest info, but also using my own experiences and knowledge and understand fully there is still so much the experts just can't know. Concrete knowledge takes time, experience, and data.
If my heightened sense of urgency saves my kiddo's life, then I have done my job.
ETA: Doctors here (US) are recommending that incoming packages or items be wiped or sanitized whenever possible before bringing into the home. This includes food packages that many people are having delivered.
I'm not having food delivered as I live too far out for such things, but can use the no touch rule as much as possible, hence leaving things outside and not touching the mail.
