Fomite-based transmission was the hypothesis after observing infection patterns aboard cruise ships, iirc.  I see no reason to doubt that fomites can be the method of transmission based on those observations, unfortunately.  

The case of the isolated/distanced woman contracting the virus from her grocery deliverer is worrisome as people have been echoing the theory that outdoor air circulates and dilutes aerosol risk down to negligible amounts (and that sunlight kills the virus, yay /s).  I have refrained from jumping into that fray.

Anyway, although patients are generally poor historians, examples like this serve to remind everyone to be vigilant about who is near you and who may be asymptomatically contagious.

The thing is that something being rare doesn't mean it's impossible. The thing about fomite transfer is that degrees matter, shaking hands is obviously stupid, but how much does it matter if you touch an object someone else touched? Touch sometime that someone else touched, then touch a different object, then wash your hands, then touch the second object again? At some point the transfers start to be immaterial.

Same thing with outdoor exposure, it obviously could happen if that jogger who just ran by is sick, but I'd be far more worried about just standing in the grocery store for an hour.
