you said “ A more contagious strain ...” do you have anything other than “store managers knew about the strain” to support this claim? I work with health experts and none of them have heard of this.
You “work with health experts” who reportedly imply that there is no single strain that is more contagious than another. No one can argue with or inform an “expert,” who is fully knowledgeable in “health.” Silenced by “experts,” I’ll keep the bookmarks to myself.
