DENGUE FEVER UPDATE
You may never have heard of Dengue Fever. It is a viral illness transmitted by mosquitos, and it is an increasing threat to travelers. Recently there have been reported outbreaks with thousands of cases in Brazil, Venezulea, Honduras, Australia and Saudi Arabia. It also occurs at lower rates in many other countries. There are occasional cases in persons in the US who have not traveled. These are secondary cases spread from returning travelers, as we do have the mosquito vector in this country.
There is no vaccine available for dengue, so the only defense is for you to take precautions to avoid mosquito bites. These include wearing long pants and long sleeve shirts, use of a good mosquito repellant (I recommend Ultrathon which is at time release formula DEET which lasts up to 12 hours), and sleeping under a mosquito net at night if your sleeping area is not sealed against mosquito entry.
There is no specific treatment for Dengue Fever which produces an illness similar to severe influenza. The interval between mosquito bite and onset of illness is usually 3 to 7 days, but may be up to 14 days. Occasionly dengue virus infection may produce fatal dengue hemorrhagic fever.
