I'm wondering why most of the cases are on the Big Island and Maui. Oahu has 75% of the state's population so with everything else being equal I'd think most of the cases would be on Oahu. I've never seen a convincing explanation for this.  Also is organically grown produce more susceptible to carrying the worms? Maybe more people eat organically or there are more carriers (slugs and snails) on the Big Island and Maui.  Despite the low total number of cases, it deserves attention because of the seriousness of the disease.
