Maine like every state has many good epidemiologists. But, in the cases of well traveled places the CDC will give the traveler all the free advice they need. In simple terms carry a lot of DEET and know when and how to use it. Beware of any gimmick trying to take your money and your health for their profit. When in the tropics use DEET before you get there and 24/7 until you leave. Always add more when going ashore or getting out of the shower or water. DEET always goes on top of the sunscreen. When you add sunscreen add another layer of DEET.
