As I started to say, every human can pass bacteria and virus to anyone during normal daily interaction in the marketplace. I am sorry your wife acquired an infexction from a healthcare facility but it cvould have just as easily been a store, resturant or bakery. If that is the best anyone can do to criticise me for how I go through life in my work, I think you are reaching pretty low for criticism. Does the patient have any obligation to not pass disease to me? SOrry, pretty lame premise.
