over the last two years this has been getting worse, with many tourists getting it everyday.There is no treatment for the illness its self, best idea is to wear mossie spray all day too, as this is when the carriers are about.
i got it in july this year and it is more than just a fever, you will feel like death and may need to be put on a drip to help you keep rehydrating once unwell.Read up on it before you go at least 5 people a day were going down with it when we were in Koh Pha Ngan.Mind you don't get done on the medical payments too or get insurance.
