What If The Outbreak Came From Underground and is The Trade Off With The Rescue Operations... Exploring all of the options and possibilities leads me to wonder about this. I know these Operations began last year and the planning itself goes back Much farther. Under the Fast Paced Nature of these Operations which are also very emotionally charged you do not have the time AT ALL to avoid the possibility of something making it to the surface, its actually inevitable.  These underground Milab and D.U.M.B bases are all dozens of levels deep and in some cases Cavernous like you would imagine for aquifors and enormous water tables. In addition they are connected globally with tunnels that are everywhere including under the sea.  If this was going to be a byproduct of the nature of the operations it would be unavoidable and you would have to plan for it in advance. And looking at the literal Circus we have going on , this scenario also fits like a glove. edit: I do have to admit, the fact of one of the earliest cases being literally a mile away from Bill Gates residence, leads me to imagine that dork going to the mall with his little vile like the cook that he is to hand pick his first victim. Either way, both plausible.
