One good thing about this disease is that it will peak and then burn out. As the population of immune people goes up the chance of a mosquito biting an infected person eventually drops to at or very near zero. At that point the virus dies out.
I wouldn't (am not going to) cancel any trips. A couple of years back Bonaire experienced very unusual weather - heavy daily rain from September to January. The mosquito population exploded. I was there for two weeks in January. Having prepared 2 sets of clothes with Sawyer's Permethrin and using Sawyer's 20% Picaridin I didn't get bit. People staying at the same place as I looked like they had chicken pox or measles. Better living through chemistry.
I'm going to St. John soon, am in the process of planning a trip to Coco View (Roatan) and Glover's Atol (Belize), and will continue to go to Bonaire. It's not like I'm all that safe at home (Upstate NY). Lyme is rampant, equine enchephalitis, West Nile, and guess what Chikungunya on Long Island. Planet warming is spreading the "tropical hot zone" ever wider. Sea level rise is probably the least of our problems.
