The CDC's website says that there has been no documented evidence that Covid19 can be spread through contact with a Fomite, or an object of transmission. The "Germ Guy" , Jason Tetro and an article by MIT Technology review say the same thing. Still I know these findings are not conclusive yet because this is a new virus and I assume testing is ongoing. So I will continue to be cautious about what I have touched outside my home. The Germ Guy guys says after a few hours Covid19 begins to degrade.

I would be wary about going into any places that have a characteristic smell. Odors are airborne bacteria and a smell means the air flow is not moving air out of a room or building fast enough to be safe from Covid 19 transmission.
