--- Quote ---The most likely route of infection for most people is hand to mucosa contact (hand to face) after touching a contaminated surface.

Right. But if you would wear a selfmade mask, then you could not touch your mouth. I still think wearing a mask would be good. Here in germany/europe it's winter and cold, it is flu-season. so there are many people coughing and sneezing who think it it just flue and who do not wear masks.

Yes, there is a mask shortage, build them for you own.

Even if wearing the mask only makes a minor difference, i think in this situation we should at least try ist. look at china/southkorea, threre they wear masks and may be have succeded.

No. They just wear masks for the placebo effect / false sense of security. Cerebus already described in detail why generic / self made masks don't work at all. The only thing which helps is to physically seperate people by keeping distance and keeping your hands clean. You are way too panicky. Just follow the advice from the experts.

When things go hairy, the last thing people should be doing is listening to "advice from the experts".

They do like my town , blew up a "low density ethylene" plant and  release petrochemistry smoke to atmosphere.  You will see that few cases are detect of coronavirus.  :-DD :-DD

New study investigating stability of HCoV-19 and SARS-CoV-1 in aerosols and on different surfaces and estimating their decay rates using a Bayesian regression model.

Cerebus:
TL;DR on the above:

SARS-Covid-2 exhibits shortest half-lives on copper and cardboard. So by the time your PCB and its packaging get to you from China it's going to be safe.  >:D


--- Quote ---No viable virus could be measured after 4 hours on copper for HCoV-19 [SARS-Covid-2] and 8 hours for SARS-CoV-1, or after 24 hours on cardboard for HCoV-19 and 8 hours for SARS-CoV-1.

Longest half-lives are on stainless steel and plastic - watch those hand rails and door knobs.


--- Quote ---HCoV-19 was most stable on plastic and stainless steel and viable virus could be detected up to 72 hours post application (Figure 1A), though the virus titer was greatly reduced (plastic from 103.7 to 100.6 TCID50/mL after 72 hours, stainless steel from 103.7 to 100.6 TCID50/mL after 48 hours). SARS-CoV-1 had similar stability kinetics (polypropylene from 103.4 to 100.7 TCID50/mL after 72 hours, stainless steel from 103.6 to 100.6 TCID50/mL after 48 hours).

--- End quote ---

Aerosol half-lives are long enough to be concerning:-


--- Quote ---HCoV-19 and SARS-CoV-1 exhibited similar half-lives in aerosols, with median estimates around 1.1-1.2 hours, and 95% credible intervals of [0.64, 2.64] hours for HCoV-19 and [0.78 , 2.43] hours for SARS-CoV-1.
