If you will be spending a lot of time in the jungle particularly during the summer months when there is a lot of standing water due to rain, please take precautions against Dengue Fever.
Dengue fever is a mosquito-borne virus affecting more than 390 million people each year. While the disease is generally mild, it can be deadly. Recent research shows dengue is between 100 and 800 years old. It likely originated in Africa or Southeast Asia and was then carried to other parts of the world through travel and trade.
