Why aren’t the airlines warning potential passengers to Hawaii about the increasing spread of dengue fever on the Big Island? It’s now centered around the Kona area, source unknown, but precautionary measures are being done in the Hilo area. Both residents and visitors are being affected.
Today I spoke to a worker at the post office who was leaving for Kona and she knew nothing of Kona’s spread of dengue fever.

Good question. I was very surprised while in Honokaa to get a flyer about it at the grocery store.
