if (of course, if and only if) the problem is to save Western civilization from autocatalytic noise (and subsequent psychic, behavioral, political, economical, cultural catapulting collapse) caused by 1,2 sneezing of Wuhan, here a funky, immediate approach;
you have to get it:
(1) thiny film (e.g. one piece of a thin film roll, made by polyethylene, used to wrap food);
(2) pocket cotton handkerchief (like the ones used by cowboys, like those popping out of the pocket of the jackets that italian Prime Minister wears, perhaps wider);
(3) scotch tape (transparent adhesive tape);
below the assembly (1-3 minutes to compose it, two or 'n' times a day);
This device is relatively safe even if your interlocutor spits in your mouth (in that case, to protect the eyes you remember that you also need protective glasses and any earplugs, disposable gloves ...);
you can get more security by spraying - on the outside of the handkerchief - a mixture of alcohol, hydrogen peroxide (H2O2) and distilled water (the composition indicated by the WHO, without glycerol); cfr Guide to Local Production: WHO-recommended Handrub Formulations (reagents for formulation 1) Revised April 2010

With this device you can travel around the city, on buses, on trains, ... in relative safety, yours and your neighbors;
instead of film roll for food you could use a waterproofing spray but the cost is high and the chemical one is probably toxic for human
