While I am not the Medical Clinic, we have not heard of any cases of it or Dengue in the last month. There seem to be fewer mosquitoes (and more flies) this year and I have seen and heard the truck spraying for mosquitoes several times.
That said, I keep a can of Raid on hand and spray around the house from time to time, especially if I see a mosquito. We also put bug spray on, especially our legs, when we go out in the evening.
I don't know Craig B., but if I understand the tone of his reply correctly I would hazard a guess that he, nor anyone close to him, has been afflicted by either of these maladies. It is very prudent to ask the question and take some precautions.
