My husbands blood tests for Dengue Fever have just been confirmed positive, 2 tests, no treatment. He's well now but was unwell on our return from Bali 4 weeks ago, flu like symptoms. The first case our Dr. has seen, he's a regular to Bali.
Please be vigilant with the spray, and get tested if you are unwell, although I'm not sure what you can do once tested positive, because all we know is that if the same strain bites he's immune but if another strain bites then he could be more unwell next time, I suppose if symptoms get worse then you would get yourself tested earlier rather than later in case complications arise.
