With respect, scientific evidence and peer review are very different things. The Grand Cayman experience just noted surely stands as more-thanb-anecdotal evidence that human activity can't be ruled out. It seems pretty clear that finding a diver who didn't decontaminate, who dove on a particular site on a certain date, and SCTLD then followed, is not a reasonable ask when the stakes are so high. If the spread can be slowed, there is surely hope that it can be mitigated.I stand by my statement there is no scientific basis for any of the precautions being recommended and will gladly stand corrected when referenced a peer reviewed article.
