I believe it has been known for about 15 years now, that ACE2 positive epithelial cells are a potential vector for the coronavirus family of viruses. I think with SARS-CoV-2 the pathogenesis is still not properly understood. For e.g. if you take a look at the ACE-2 expressing cell distribution, the tongue and oral cavity are very high on the list. And yet, there is no current guidance on disinfecting food before eating it, even though its a potentially high-risk route of infection. https://www.ncbi.nlm.nih.gov/pubmed/16690935 https://www.ncbi.nlm.nih.gov/pubmed/16690935
