Thanks, you too. My friends at other hospitals and in other cities/countries are in much more precarious situations.
Mate, no. With a dangerous droplet-borne viral pandemic developing, you shouldn't need your CSO to tell you whether or not you should shake hands with a few dozen people a day—you should decide not to, on your own, and if your CSO encourages you to shake hands, you should question their judgement and disregard their recommendation wrt handshaking. The cost of not shaking hands is, in this context, essentially zero.
